She shared some of the challenges that people with voice disorders face and emphasized the importance of involving them in development of innovative products to help ensure that they can meet their specific needs to improve their quality of life.
Megan Urbano: Voice Specialized Speech Pathologist Megan Urbano discussed the differences between voice and speech. In short, voice was determined to be the sound signal as shaped by 3 subsystems—respiratory, phonatory, and resonatory. The respiratory system is comprised of the lungs and the flow of air through the vocal folds. High airflow produces a breathy quality, while low airflow can produce either a strained or rough vocal quality. The phonatory system is isolated to the vocal folds and the sound wave they create when they come together. Furthermore, vocal folds shape pitch (high and low) and vocal intensity (loud and quiet). Finally, the resonatory system shapes the remainder of the vocal tract to dampen or amplify soundwaves, creating a perception of the locus of a sound (e.g., a “throaty” vs. “nasal” sound). This was contrasted against speech, which can also be thought of as articulation, or how sound is shaped into language. An example given was as follows; Imagine a person speaking in English and then the same person speaking in Spanish. While their voice quality should be the same, the articulation, and therefore their speech, will be altered.
Akash Raj Komarlu: Akash summarized the current state of AI speech technology and how it can be used for people with voice disorders.
Joris Castermans: Joris Casterman shared his personal journey with stuttering and how that led to the development of a successful innovation in the assistive technology field with an app called Whispp. He shared his startup learnings and 6 key success factors which include: having a personal intrinsic motivation and drive, having a team with intrinsic motivation and drive, knowing and being close to your target group, never underestimating the importance of good UI design, having a unique and clear positioning of your solution and company, embracing the experts and your ambassadors. He concluded the presentation with a powerful video of people sharing the impact that voice disorders have on every aspect of their lives.
Charlie Reavis: Charlie Reavis concluded the workshop by expressing his gratitude to all the speakers for their dedication to helping people with voice conditions. As someone living with spasmodic dysphonia, he appreciated seeing the partnership between professionals and those affected by voice disorders.

Presentation Summaries:
Maria Powell: Dr. Powell introduced herself and the other presenters as well as their roles in the program. She emphasized the importance of audience interaction and feedback, though the session had numerous presentations to cover.
Vardit Ravitsky: Dr. Ravitsky addressed the challenges of obtaining informed consent for AI-powered voice data collection. She highlighted the complexity of ensuring consent is truly informed given the unpredictable future uses and re-identification risks associated with the data. This uncertainty makes it difficult to fully inform participants about the potential implications of their participation. Dr. Ravitsky detailed the protocols for categorizing patient data into four diagnostic groups: mood disorders, respiratory disorders, voice disorders, and neurological disorders. Each group involves specific assessments and speech tasks. For mood disorders, the protocols include the PANAS, custom affect scale, DSM-5 criteria for PTSD and ADHD, and open-ended speech tasks. Respiratory disorders protocols involve different indices in the LCQ, breath sounds, and cough sounds. For voice disorders, the protocols include quality of life questionnaires, personal severity ratings, and specific speech tests. Neurological disorders protocols feature the Winograd task, word-color Stroop test, productive vocabulary tests, and the retelling of the Cinderella story.
Dr. Ravitsky emphasized the importance of clinical validation to ensure diagnostic accuracy based on current gold standards. She aims to confirm diagnoses through medical records while respecting privacy concerns. However, the lack of standardized diagnostic tests for some conditions poses challenges. Practical considerations include front-loading voice samples before medical procedures and adapting protocols in real-time. Dr. Ravitsky also stressed the need for sensitivity to emotional responses in open-ended speech tasks.
Maria Powell: Dr. Powell discussed the concept of hypothesis-agnostic protocols, which are central to their work. These protocols are designed to be flexible and applicable to multiple hypotheses. Currently, they have four protocols in play for mood, voice, respiratory, and neurological disorders. The goal is to create a protocol that can accommodate various hypotheses, achieved through their protocol development process. Dr. Powell explained that they aim to gather as much information as possible from medical records. While clear diagnoses can confirm the data, they may not always have the gold standard diagnostic tests. They document this gap and supplement it with other standards, such as MRI scans, to provide additional context.
In terms of patient recruitment, they focus on those who have the target diagnoses. For example, patients with breathy voices are included under voice disorders, even if they don't have a specific sound source. This approach ensures they capture relevant data across different conditions. The protocol includes a master list of phrases and questions, with specific subsets for each diagnostic group. All participants complete a core set of tasks, and additional tasks are based on their specific diagnoses. They have the capability to shuffle tasks but currently prioritize practical considerations, such as front-loading voice samples for patients who might be pulled into procedures. Dr. Powell acknowledged the practical challenges of collecting data in a clinical setting, particularly with patients undergoing treatments. They aim to improve this process in the future, ensuring a comprehensive and flexible approach to data collection across different disorders.
Yael Bensoussan: Dr. Bensoussan introduced the session by noting that the work being discussed was conducted by Ruth Bahr and Shaheen Awan and their team. She praised their expertise in acoustics, highlighting their extensive lab experience. The team had conducted experiments to compare different microphones, including iPhones, tablets, and high-end equipment, using a Kemar, a medical mannequin designed to simulate human vocal resonance. They tested various microphones and found that maintaining a consistent distance from the microphone was crucial for reliable data. Changes in distance significantly affected the accuracy of measurements, which was particularly noticeable with nasal interference and plosives when the microphone was too close to the mouth. Their recommendation for clinical studies was to use headset microphones to ensure a consistent distance. They found that a distance of about three inches from the mouth provided the best sound quality without interference. They also emphasized the importance of using gain adjustment platforms and integrating technology to automatically adjust microphone gain based on distance and volume.
Alexandros Sigaras: Alexandros Sigaras began by acknowledging that he had the privilege of leading the team responsible for building tools to ensure participants’ voices are heard. One of his key responsibilities is addressing ethical concerns. He asked the audience how many of them build tools, engaging those involved in similar work. Sigaras discussed the importance of feasibility, accessibility, and scalability in tool development. He shared that a significant challenge was ensuring participants could correctly identify and press the recording button, as about 80% initially struggled with this. He emphasized the value of feedback from clinicians and participants, which has been crucial in improving the tools.
He highlighted their use of the Kemar mannequin for acoustic testing, which helps ensure reproducibility. They tested various devices, noting that microphone gain differs across devices like iPads and iPhones. Sigaras mentioned the differences in the number of microphones across Apple devices, which affects audio quality. The team measured headset performance to prevent audio clipping and found that maintaining the right distance is key for accurate data collection. This approach benefits both remote and clinical data collection settings.
Sigaras concluded by discussing scalability, particularly within the Apple ecosystem. Sigaras emphasized the goal of making the tools accessible to all participants, whether or not they have a voice disorder. Remote enrollment and consent are already live, with ongoing efforts to improve remote data collection. He invited participants to enroll and contribute to the Bridged AI program.
Jordan Lerner-Ellis: Dr. Lerner-Ellis focused on the challenges and strategies for recruiting and enrolling patient participants. He outlined the criteria for establishing high-volume expert clinics, which are specialized units at participating institutions with high patient volumes for specific diseases. Despite these clinics’ potential, success can vary due to factors like remote clinic locations.
Dr. Lerner-Ellis shared experiences from sites like Bridgepoint and Baycrest in Toronto, noting that even high-volume clinics like those at the Center for Addition and Mental Health, sometimes recruit only one or two new participants per month. Recruiting from some jurisdictions such as In Ontario, where there are over 140 hospitals, benefits from centralized research ethics board approvals through systems like clinical trials Ontario (CTO), which is being taken advantage of. He emphasized the importance of specialized focus and partnerships, such as with Life Labs for remote and collection of blood samples. He mentioned that recruiting Alzheimer's disease patients often requires substitute decision-makers and is more effective in the inpatient settings. Dr. Lerner-Ellis pointed out the need for additional staff to assist with coordination and data collection, as clinicians are often too busy to handle these tasks themselves. Dr. Lerner-Ellis emphasized the importance of providing research assistants to facilitate data collection and ensuring the involvement of necessary staff for successful recruitment and data gathering. In conclusion, he invited attendees to the tech fair and poster session for further engagement and networking.
Workshop 5: Unlocking the Secrets of Voice: A Deep Dive into Physiology and Signal Processing
Objectives: The educational workshop provided a comprehensive understanding of voice analysis by exploring three key domains. First, it distinguished between voice and speech, examined how the ear perceived sound vs. what acoustic data revealed, and assessed quality ratings to demonstrate how AI could enhance voice analysis. Second, it delved into available acoustic measures, their significance, multi-dimensionality, and the pros and cons of existing methods, illustrating the need for AI-driven approaches. Lastly, it showcased how deep learning and transformer models encoded nuanced variability in speech, emphasizing how to manage potential information loss in spectrograms and interpret AI models trained on voice, while offering strategies to make Voice AI more explainable.
Presenters:
• Ruth Bahr, PhD, CCC-SLP, BCS-CL: Professor, Communication Sciences and Disorders, University of South Florida
• Jenny Vojtech, PhD: Research Assistant Professor, Department of Speech, Language, & Hearing Sciences Boston University
• James Anibal: DPhil student at Reuben College, an NIH-Oxford Scholar, and a bioinformatics instructor at the Foundation for Advanced Education in the Sciences
Presentation Summaries:
Ruth Bahr: Dr. Bahr began her presentation by discussing the profound nature of the human voice and the importance it holds in one's identity. She quoted Daniel Day-Lewis, who called the voice “the fingerprint of the soul,” emphasizing how personal and irreplaceable it is for individuals. She made a clear distinction between voice and speech, explaining that the voice is the sound produced by airflow and vocal fold movement, while the vocal tract modifies this sound to form speech. She explained the anatomy and physiology of the larynx, focusing on how the vocal folds vibrate to produce sound. She described the relationship between air pressure, airflow, and vocal fold movement in generating different acoustic signals. Dr. Bahr explored vocal biometrics, noting the unique variability of individual voices and the complexity involved in distinguishing pathological changes from intentional modifications. She concluded by underscoring the challenges of identifying biomarkers, given the variations in speech patterns and the emotional connection people have with their own voices.
Jenny Vojtech: Dr. Vojtech took the stage next, focusing on the role of acoustic measures in clinical voice assessment. She detailed the recommendations made by the American Speech-Language-Hearing Association (ASHA) for key acoustic measures like Sound Pressure Level (SPL), fundamental frequency, and cepstral peak prominence (CPP). She critiqued the continued use of measures like jitter and shimmer, which, despite being traditionally used, are no longer recommended due to their lack of clear physiological ties and poor handling of severe dysphonia. She highlighted the limitations of these acoustic measures, noting how environmental factors can impact recordings and how fundamental frequency and SPL are not always directly linked to what the ear perceives. She stressed the need for automating and validating these measures in clinical settings to ensure consistency and reliability. The adoption of these measures would provide a comprehensive supplement to perceptual assessments, enabling more accurate tracking of voice quality changes over time.
James Anibal: James Anibal followed, turning the conversation toward deep learning and artificial intelligence (AI) in voice analysis. He advocated for the power of AI to analyze the complex, nonlinear combinations of features in the human voice and correlate them with disease status or diagnostic methods. Anibal described the role of self-supervised learning in teaching AI models to detect patterns by predicting missing data points. He expanded on contrastive learning, an approach that identifies “same” and “different” pairs to refine model predictions, allowing the AI to focus on the nuances of voice biomarkers. Anibal acknowledged the challenges and opportunities in this domain, noting that while these models are powerful, they require vast amounts of data and face issues related to data privacy and the explainability of their outputs. Despite these challenges, he emphasized the potential of integrating multimodal models with existing language models like GPT to facilitate more nuanced and comprehensive voice analysis, especially for clinical purposes.
