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. ## Key features - Interactive auditory training - Self-paced modules - Adjustable difficulty - Audio-visual feedback - Sound and speech discrimination practice - Phonetic contrast training ## Recent user reviews (10 of 27) All indexed reviews: https://appshunter.io/ios/app/i-angel-sound/id839199212/reviews.md ### 5/5 — Perfect 🌟 *2026-01-02, version 1.4.1* Although this app seems outdated the content certainly is not. It is free and genuinely helps, I’m learning to decipher between similar constants and I can choose to turn on a noisy background which makes it more authentic ### 5/5 — Good starter app *2025-12-30, version 1.4.1* 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. ### 1/5 — Who did this? *2025-08-22, version 1.4.1* The worst app ever. No direction at all on how to navigate the app. Poorly designed. Doesn’t deserve even one star. ### 4/5 — Nice idea but this is useless right now. *2025-04-27, version 1.4.1* Very Buggy. Constant refresh needed and sometimes only the end of a word gets repeated after multiple refreshes. VERY FRUSTRATING. Grading is wonky. ### 1/5 — Lack of Accessibility for deafblind, Low Vision and Visual impaired *2024-08-28, version 1.4.1* I was disappointed to find that the I-Angel Sound app for iPhone and iPad does not offer Dark Contrast or adjustable text size, which are vital accessibility features for users with Low Vision and Visual Impaired. To address this, I-Angel Sound should prioritize adding accessibility options to their app and website. I do t like bright white background and blue text is difficult to read. ### 2/5 — Too many issues *2024-04-23, version 1.4.1* This app could be great, but it doesn’t work… a lot. Too many time I have to hit the repeat button because it’s just chiming instead of saying a word. Some days it just won’t say the word and I just give up. ### 1/5 — Repeat until it plays sound *2024-04-16, version 1.4.1* You have to repeat/hit refresh until the app plays sound. I used this app with my audiologist at initial stimulation, and I could not hear a thing, she told me that I would eventually hear it, but it was clearly a bug with the app. I am a re-implant, so I knew what to be expecting, and had previously used this app. There are times I have to hit refresh 10 times before I actually hear something in my implanted ear. 1 star. ### 2/5 — It’s ok *2024-04-11* It’s free so I guess I can’t expect a lot. It’s just ok. Most of the time you have to have it repeat the word a few times. It won’t say the work just a sound. Eventually, when it won’t say the word at all I just call it quits for the day and move on to another app for training ### 3/5 — Good app, but… *2024-03-27, version 1.4.1* I believe the content of this app can be of great value to a cochlear implant recipient doing rehab, but it seems to disconnect the audio between each exercise. To overcome this problem, I repeat the audio clip until it plays. This should not be necessary. ### 2/5 — Need updating *2023-11-16, version 1.4.1* Need to update the app to keep current ## Frequently asked questions about i ### What does i-Angel Sound do? i-Angel Sound is an interactive auditory training program that allows users to independently practice and improve their listening skills at home.
