Features & Capabilities

Welcome to i-Angel Sound, an interactive auditory training program that lets you take control of your listening rehabilitation independently at home. You gain practice in discriminating and identifying sounds and speech components through a series of self-paced modules that cover different aspects of the listening process. The level of difficulty can be adjusted to match your developing listening skills. The program provides audio-visual feedback. Focused on practice and improvement of your listening skills, i-Angel Sound compliments your clinic rehabilitation program. The i-Angel Sound is developed by Inconvenient Solutions, the mobile division of TigerSpeech Technology Inc. and Emily Fu Foundation, which is devoted to develop innovative speech software for hearing impaired and children to facilitate the learning of sounds. The program contains a few thousands sounds from several categories, including environmental sounds, the name of common foods, the name of familiar animals, and monosyllabic words. The phonetic contrast training protocols used in the monosyllabic word training reinforce the brain's ability to distinguish between phonemes which are the building blocks of language. The program is suitable for anyone who want to improve the sound perception or simply to enjoy listening to all kinds of sounds, including environmental sounds and music.

User Reviews

The app shows potential as a CI rehab tool with daily progress and clinician endorsement, but reliability and accessibility problems dominate reviews. Users report frequent bugs, audio playback issues, outdated compatibility, and content gaps, with calls for updates. Despite positive sentiment and professional support, overall experience is hampered by stability and accessibility challenges.
Pros
  • Useful tool for cochlear implant rehab with observable daily progress.
  • Endorsed by audiologists / clinicians.
  • Generally positive sentiment with willingness to recommend.
Cons
  • Frequent bugs and stability issues (crashes, freezes, and constant refresh needed).
  • Audio playback problems (words not spoken, need to refresh, or no audio).
  • Accessibility gaps (no adjustable font size or contrast; not 508 compliant).
  • Outdated compatibility / infrequent updates (issues on newer iOS and devices).
  • Training content issues (missing words and flawed grading).
Recent reviews
Free, easy way to get into CI rehab and training. It’s pretty simple but is great for the first month or two of rehab. Would recommend.

The worst app ever. No direction at all on how to navigate the app. Poorly designed. Doesn’t deserve even one star.

Very Buggy. Constant refresh needed and sometimes only the end of a word gets repeated after multiple refreshes. VERY FRUSTRATING. Grading is wonky.
