Speech Accessibility Project

People With Speech Disabilities Contributing Speech Samples for Improved Accessibility of Speech-Enabled Devices

Source: ClinicalTrials.gov · Last updated 17 Aug 2025

Brief summary (registry, in English)

The goal of the Speech Accessibility Project at the University of Illinois Beckman Institute (https://speechaccessibilityproject.beckman.illinois.edu) is to collect, annotate, and curate a shared database of speech samples from people with atypical speech, and share this data set with researchers at other organizations. This two-year project plans to collect 1,200,000 speech samples from 2,000 people, each of whom will provide 600 samples. In Year 1, the initial focus will be people with Parkinson's. In Year 2, four more etiologies of interest will be recruited: Amyotrophic Lateral Sclerosis (ALS), Cerebral Palsy (CP), Down Syndrome (DS), and Stroke. UIUC will build an open-source software infrastructure to collect annotated speech samples and share these data in an appropriately secure fashion with researchers from our partner technology companies (and eventually, other organizations as well) so that they can use these data to improve their automatic speech recognition algorithms. This project promotes diversity, equity, and inclusion by helping technology companies to fully support all types of speech, and it is also more efficient and less burdensome for these specialized patient populations to have one centralized "collector" of speech samples.

What you commit to

  • Study type: Observational
  • Participants enrolled: 485
  • From 15 Mar 2023 to the primary completion date, 29 Mar 2025
  • 2 sites in 1 country
  • Visits and tests: ask the trial team, the registry does not list them

Built from the registry fields of ClinicalTrials.gov. It describes the study, not your situation.

Who cannot take part

Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.

Other

  • Is a resident of the State of Washington, Texas, or Illinois (because these states have privacy laws that would not allow us to collect 'voice prints')
  • If quality control screening of initial speech samples "fails" because of poor data quality (e.g., poor quality recording environment, or person's speech is "too typical" and not sufficiently interesting to continue collecting)

Who the study is looking for

  • Adult (age \>= 18 years)
  • Self-reported diagnosis of Parkinson's Disease, ALS, CP, DS, or Stroke
  • Reads and speaks English in the form of complete sentences
  • Has a valid email address
  • Ability to access web browser to participate in study

Age in the registry: 18 years to - · Sex: All · Does not accept healthy volunteers
