COG-MHEAR: Towards cognitively-inspired 5G-IoT enabled, multi-modal Hearing Aids

Lead Research Organisation: Edinburgh Napier University
Department Name: School of Computing

Abstract

Currently, only 40% of people who could benefit from Hearing Aids (HAs) have them, and most people who have HA devices don't use them often enough. There is social stigma around using visible HAs ('fear of looking old'), they require a lot of conscious effort to concentrate on different sounds and speakers, and only limited use is made of speech enhancement - making the spoken words (which are often the most important aspect of hearing to people) easier to distinguish. It is not enough just to make everything louder!

To transform hearing care by 2050, we aim to completely re-think the way HAs are designed. Our transformative approach - for the first time - draws on the cognitive principles of normal hearing. Listeners naturally combine information from both their ears and eyes: we use our eyes to help us hear. We will create "multi-modal" aids which not only amplify sounds but contextually use simultaneously collected information from a range of sensors to improve speech intelligibility. For example, a large amount of information about the words said by a person is conveyed in visual information, in the movements of the speaker's lips, hand gestures, and similar. This is ignored by current commercial HAs and could be fed into the speech enhancement process. We can also use wearable sensors (embedded within the HA itself) to estimate listening effort and its impact on the person, and use this to tell whether the speech enhancement process is actually helping or not.

Creating these multi-modal "audio-visual" HAs raises many formidable technical challenges which need to be tackled holistically. Making use of lip movements traditionally requires a video camera filming the speaker, which introduces privacy questions. We can overcome some of these questions by encrypting the data as soon as it is collected, and we will pioneer new approaches for processing and understanding the video data while it stays encrypted. We aim to never access the raw video data, but still to use it as a useful source of information. To complement this, we will also investigate methods for remote lip reading without using a video feed, instead exploring the use of radio signals for remote monitoring.

Adding in these new sensors and the processing that is required to make sense of the data produced will place a significant additional power and miniaturization burden on the HA device. We will need to make our sophisticated visual and sound processing algorithms operate with minimum power and minimum delay, and will achieve this by making dedicated hardware implementations, accelerating the key processing steps. In the long term, we aim for all processing to be done in the HA itself - keeping data local to the person for privacy. In the shorter term, some processing will need to be done in the cloud (as it is too power intensive) and we will create new very low latency (<10ms) interfaces to cloud infrastructure to avoid delays between when a word is "seen" being spoken and when it is heard. We also plan to utilize advances in flexible electronics (e-skin) and antenna design to make the overall unit as small, discreet and usable as possible.

Participatory design and co-production with HA manufacturers, clinicians and end-users will be central to all of the above, guiding all of the decisions made in terms of design, prioritisation and form factor. Our strong User Group, which includes Sonova, Nokia/Bell Labs, Deaf Scotland and Action on Hearing Loss will serve to maximise the impact of our ambitious research programme. The outcomes of our work will be fully integrated, software and hardware prototypes, that will be clinically evaluated using listening and intelligibility tests with hearing-impaired volunteers in a range of modern noisy reverberant environments. The success of our ambitious vision will be measured in terms of how the fundamental advancements posited by our demonstrator programme will reshape the HA landscape over the next decade.

Planned Impact

Significant impact beyond the academic environment is envisaged through this multi-disciplinary programme:

*Impact on people with hearing loss*
Over 10 million people in the UK (~350 million worldwide) currently suffer from debilitating hearing loss, at a cost of ~£450M/year to the NHS, and this figure is expected to rise to 14.5 million by 2031. People with serious hearing loss often find themselves socially isolated with a range of adverse health consequences. Even a modest improvement in hearing however, can have a significant impact on an individual's social and work life. Our proposed technologies will transform real-time, privacy-preserving and domain-independent learning capabilities, to deliver robust speech intelligibility enhancement and end-user cognitive load management, in the hearing aids (HAs) of 2050. Our technical work programme is focused on this contribution, and the wide number of released societal and individual benefits that follow from it. For example, the data we can obtain from our pilot (on/off-chip) HA fitting and clinical validation, in smart assistive care homes and other real-life environments, could potentially enable: remote fitting, and usage training of HAs for end-users and audiologists - resulting in resource savings and relevance in developing countries. In care homes, where hearing loss affects ~90%, a well-functioning communication channel (even by remote communication) in which the emotional state can be securely sensed and transported, would be an ambitious clinically relevant use case. This would also benefit the visually impaired as it complements the visual processing in speech perception.

*Hearing aid industry*
Our proposed audio-visual (AV) HAs can have a considerable impact on the HA industry, as demand for future AV aids should rapidly complement inferior Audio-only devices. The UK's global reputation in hearing research could thus be transformed simulating major global HA manufacturing. There are clear precedents for hearing science rapidly transforming hearing technology, e.g. multiple microphone processing and frequency compression have been commercialised to great effect. COG-MHEAR foresees AV processing as the next timely step forward, as previous barriers to AV processing are being overcome: wireless 5G and Internet of Things (IoT) technologies can free computation from having to be performed on the device itself, and wearable computing devices are becoming powerful enough to perform real-time face tracking and feature extraction. AV HAs will also impact on industry standards for HA evaluation and clinical standards for hearing loss assessment. Plans for realising industrial impacts are detailed in the Pathways to Impact and Workplan.

*Applications beyond hearing aids*
We foresee impact in several areas (see Impact Pathways), including cochlear implant signal processing, automatic speech recognition systems, multisensory integration, general auditory systems engineering, and clinical, computational, cognitive and auditory neuroscience. Beyond HAs, novel multimodal ecological momentary assessment tools could be developed, transforming existing sparse, unimodal commercial systems of our User Group members, e.g. Sonova. These could be exploited to personalise the design and usability of other medical instruments to enhance personal product experience. Our proposed wireless-based emotion detection system could extend to emotion-sensitive robotic assistants/companions, that could be of interest to smart care homes. Beyond health, our research will deliver a step change in the critical mass of UK engineering and physical science skills to tackle emerging challenges in signal processing. The potential of our disruptive technology can be exploited in teleconferencing and extremely noisy environments e.g. dynamic environments and situations where ear defenders are worn, such as emergency and disaster response and battlefield environments.

Description Key findings and achievements of the COG-MHEAR Award to date include:
(1) Participatory co-design with end users and ongoing evaluation of the world's first real-time multimodal hearing assistive technology demonstrators, including hardware and software implementations, that autonomously adapt to the nature and quality of their visual and acoustic environmental inputs. This has led to significantly enhanced intelligibility in noise, with reduced listening effort or cognitive load. A software prototype of the MVP has also been optimised for use in web-based video communication, which has been shown to transform the listening and conversational experience for both normal and hearing-impaired individuals.
(2) The developed software and hardware prototypes have been evaluated through integration with commercial hearing aids. In pilot clinical testing with hearing aid users, our prototypes have shown the potential to transform the performance of current state-of-the-art commercial aids, delivering a statistically significant improvement in listening and intelligibility experiences in real-world, noisy environments. Prototype demonstrations have been regularly showcased both nationally and globally, including by organising international workshops and challenges as part of leading international conferences, such as the premier 2022 IEEE EMBC, the 2023 IEEE ICASSP, ISCA's flagship 2023 Interspeech and 2024 Interspeech conferences, the biennial 2024 IHCON, the 2024 WCA, and in supplements to the journal JASA. Patent applications have been submitted for developed prototype technologies, and funding applications are in progress for spinout formation.
(3) Development of the world's first web-based multi-modal speech enhancement demonstrator tool, which has been made openly available as a benchmark resource for research and innovation. This tool shows how recordings of speech in noisy environments can be multi-modally processed, both locally and in the cloud, to remove background noise and make the speech easier to hear.
(4) The disruptive development of a robust privacy-preserving radio frequency (RF)-based lip-reading framework to address user privacy concerns associated with the use of conventional (e.g., video camera-based) sensing approaches in future multi-modal hearing aids. The innovative framework has demonstrated a unique ability to read lips under face masks by employing Wi-Fi and radar as enablers of RF sensing technology. The pioneering study has been published in Nature Communications, and datasets have been made openly available.
(5) In a user group-prioritised use case, a novel privacy-preserving radio-frequency-based approach has been developed for British Sign Language (BSL) detection, to aid communication for hearing-aid users who use sign language.
(6) COG-MHEAR has pioneered user and environmentally context-aware solutions for multimodal hearing-aid users, leveraging off-the-shelf Wi-Fi networks for contextual activity monitoring and indoor localisation via intelligent wireless walls. Key findings were published in Nature Light, and associated datasets have been made openly available as new benchmarks for the global research community.
(7) Organisation of the world's first large-scale audio-visual speech enhancement (AVSEC) Challenge, utilising real-world TED Talks. The Challenge was organised as part of the leading IEEE Spoken Language Technology (SLT) Workshop, Qatar, 9-12 Jan 2023. Our team developed a new baseline pre-trained deep neural network model, which was made openly available to participants, along with raw and pre-processed audio-visual datasets-derived from real-world TED talk videos-for training and development of new audio-visual models to perform speech enhancement and speaker separation at signal-to-noise ratio (SNR) levels that were significantly more challenging than typically used in audio-only scenarios. The Challenge evaluation utilised established objective measures (such as STOI and PESQ, for which scripts were provided to participants), as well as a new audio-visual intelligibility evaluation method developed by the COG-MHEAR teams for subjective evaluation with human subjects. The new baseline model, real-world datasets, and subjective audio-visual intelligibility testing method are continuing to be exploited by researchers in speech and natural language communication and hearing assistive technology applications. Our COG-MHEAR team, based at Edinburgh Napier University, won first place in the Challenge, based on an independent subjective audio-visual evaluation carried out by researchers at the University of Edinburgh. This demonstrated the efficacy of our novel audio-visual speech enhancement models compared to global benchmark models.
(8) Organisation of the 2nd COG-MHEAR International Audio-Visual Speech Enhancement Challenge (AVSEC-2), which featured as an approved Challenge at IEEE ASRU 2023, 16-20 Dec 2023. AVSEC-2 received a higher number of submissions compared to the first challenge, and we were pleased to see high-profile companies, such as Mitsubishi, among the participants. Moreover, there was an increase in the performance of the best-performing systems.
(9) Organisation of the 3rd COG-MHEAR International Audio-Visual Speech Enhancement Challenge (AVSEC-3), which featured as a Satellite Workshop at 2024 Interspeech. AVSEC-3 featured a first-of-its-kind low-latency AVSEC track and continued to see an increase in the performance of the best-performing systems. The data produced from the challenges has enabled us to gain further understanding about the role that features of the audio and visual components play in intelligibility; we also investigated how intelligibility is affected when audio-only and audio-visual stimuli are presented, leading to important findings about the efficacy of speech enhancement in in-person settings. The annual challenges have provided excellent global advocacy for COG-MHEAR, bringing opportunities to strengthen the audio-visual speech enhancement community and bringing together interdisciplinary researchers to work towards improving future speech and hearing technologies. Challenge prizes for winners and runners-up are sponsored by Sonova.
(10) Our ongoing workshops with hearing aid (HA) users included an in-depth workshop organised in November 2023. The pilot testing in a range of realistic, challenging noisy environments found that our current WP1 technology assisted with clarity of speech in noise across all participants with hearing loss. However, user feedback also guided us to make several improvements to the tests. These included: minimising unnecessary noise that quickly causes fatigue; simplifying questions; ensuring that tests are 'double blind' for both the talker whose voice is to be identified and the participant; and making participants aware that some of the tests are by design very difficult. In a further session with HA users, industry representatives, and audiologists, we asked audiologists what they think of our proposed AV test design, with a particular focus on the instructions to be given: would they be explicit enough for patients to perform the tests without clinical assistance? Attendees at the meeting advised on ways of clarifying and simplifying the tests.

Title Multi-modal Speech Enhancement Demonstrator Tool 
Description We developed the world's first open web-based demonstrator tool that shows how recordings of speech in noisy environments can be multi-modally processed to remove background noise and make the speech easier to hear.

Impact This innovative demonstrator tool was showcased at an international workshop organised as part of the 2022 IEEE Engineering in Medicine and Biology Society Conference (EMBC) in Glasgow, 11-15 July. Around 40 Workshop participants (including clinical, academic and industry researchers) were provided with an interactive hands-on demonstration of the audio-visual speech enhancement tool. The tool demonstrated, for the first time, the technical feasibility of developing audio-visual algorithms that can enhance speech quality and intelligibility, with the aid of video input and low-latency combination of audio and visual speech information. This served to educate participants and demonstrated the potential of such transformative tools to extract salient information from the pattern of the speaker's lip movements and to contextually employ this information as an additional input to speech enhancement algorithms, in future multi-modal communications and hearing assistive technology applications.

Impact The Challenge has provided excellent advocacy for COG-MHEAR, bringing opportunities to strengthen the audio-visual speech enhancement (AV SE) community and bring together interdisciplinary researchers to work towards improving future natural language speech and hearing technologies. AVSEC-2 received a higher number of submissions compared to the first challenge, and we were pleased to see high-profile companies such as Mitsubishi among the participants. Moreover, there was an increase in performance of the best performing systems for multimodal speech-in-noise processing. The data produced from the challenge has enabled us to gain further understanding about the role that features of the audio and visual components play in intelligibility; we also investigated how intelligibility is affected when audio-only and audio-visual stimuli are presented, leading to important findings about the efficacy of speech enhancement in in-person settings. Our teams developed a new baseline pre-trained deep neural network model and made this openly available to participants, along with raw and pre-processed audio-visual datasets - derived from real-world TED talk videos - for training and development of new audio-visual models to perform speech enhancement and speaker separation at signal to noise (SNR) levels that were significantly more challenging than typically used in audio-only scenarios. The Challenge evaluation utilised established objective measures (such as STOI and PESQ, for which scripts were provided to participants) as well as a new audio-visual intelligibility testing method developed by the COG-MHEAR teams for subjective evaluation with human subjects. The latter was further refined as part of AVSEC-2 for evaluating AV SE systems at scale using a fully validated keyword-spotting design that was presented at ICASSP 2023. The new baseline model, real-world datasets and subjective audio-visual intelligibility testing method are continuing to be exploited by researchers in speech and natural language communication and hearing assistive technology applications.

Title COG-MHEAR IoT (Internet-of-Things) Transceiver Demo 
Description A video demonstrating a first-of-its-kind prototype of a 5G Internet of Things (IoT) enabled hearing-aid. In the demo, the universal software radio peripheral (USRP) on the left, acts as an IoT device (hearing aid), and the USRP on the right, acts as an access point/base station and server for Cloud-based implementation of machine learning algorithms. The channel between the left IoT device to the access point is termed as an uplink channel and the channel between the access point and the IoT device is termed as a downlink channel. To enable real-time communication of audio-visual (AV) information from the IoT device to the access point, the uplink channel supports varying data-rates and hence utilises a long-term evolution (LTE) based modified frame structure developed for uplink data transmission. This supports 1.4 MHz and 3 MHz bandwidth with different modulation and code-rates for error correction codes. On the other hand, the access point only transmits audio information to the IoT device and hence supports a fixed data rate, by utilising an LTE-based modified frame structure with 1.4 MHz bandwidth.

Title Deep learning multi-user communication 
Description A one to many downlink system (e.g. wireless base-station 110 and user devices 120/130). The transmitter and receiver devices are each provided with a deep learning function 112/122/132 (e.g. a deep neural network, DNN) encoding and decoding user data. The deep learning functions are trained to optimise error free recovery of input data streams 101 at each user device 121 (the overall system essentially functions as an auto-encoder). The encoded data is subject to channel impairments 103/104 before being input to the decoder. The training may involve varying the channel impairment parameters (e.g. signal to noise ratio). Once trained the en/decoders are used to process live user data. An uplink version with a deep learning encoder per user device and a common base-station deep learning decoder is also claimed.

The Workshop programme included keynote talks by the project PI and Work-Package Leads, an interactive poster session showcasing collaborative research by postdoctoral and doctoral researchers, and a real-time demonstration of our multi-modal minimum-viable product (MVP) operating in live web-based video conferencing environments. This gained appreciation from participants, including clinicians, end users and industry representatives, and leading national and international academics and researchers. The presentations stimulated lively discussions afterwards, with some participants requesting more information, and others expressing an interest to exploit our innovative, contextual multi-modal processing approach in their respective academic and clinical research and industry-led projects and activities. Plans for new collaborations were also discussed with some participants.

Results and Impact How will hearing aid users wear and use AV hearing assistive technology and how can a camera be worn as part of hearing assistive technology?
During public engagement sessions at the Edinburgh Festival Fringe in August 2023, this particular question was addressed in two shows as part of the Cabaret of Dangerous Ideas presented by Dr Dorothy Hardy. These shows were conducted with simultaneous translation into British Sign Language (BSL) and were included in the Edinburgh Deaf Fest programme. The comedic presentation of the research, accompanied by large props, sparked numerous questions and discussions, and prompted new inquiries about the user group.

Primary Audience Professional Practitioners
Results and Impact A discussion about the practicalities of wearing the multi-modal hearing aids that are being developed in the COG-MHEAR research programme. Most of the participants were hearing aid users. They were clinicians, audiologists and an industry representative. They joined the workshop remotely on Teams. They included clinicians and audiologists, plus an industry expert from Sonova. The wealth of expertise from their own and their client's use of hearing aids was evident and valuable.
The suggestions and queries that arose have been important in focusing the research programme to ensure that privacy is preserved with the new hearing aids, and to address issues around wearability and usability.
The results of the workshop were presented as a paper and poster at UK Speech 2022 on 6th September 2022 at the University of Edinburgh.
