Technology has become one of the most practical allies for people managing hearing difficulties. Both major smartphone platforms now offer built-in accessibility features designed specifically for hearing health — many of which most people have never activated. Combined with a growing ecosystem of dedicated hearing apps, modern smartphones can meaningfully reduce the friction of daily life for anyone with hearing loss.
Built-In iPhone Features
Live Listen. Available through Control Center, this feature turns your iPhone into a remote microphone. Paired with compatible hearing aids or AirPods Pro, it streams audio directly to your ears from wherever your phone is placed — across a table, near a speaker, or in a meeting.
Sound Recognition. This feature continuously listens for sounds like a doorbell, smoke alarm, baby crying, or knocking — and sends a visible notification to your phone when it detects them. It runs silently in the background without recording anything.
Hearing Health in the Health App. iPhone and Apple Watch can measure environmental sound levels and alert you when you're in a loud environment that could cause hearing damage over time.
Subtitles and Captions on Demand. iOS offers real-time caption support across FaceTime, phone calls, and media apps — turning spoken audio into on-screen text that keeps pace with conversation.
Built-In Android Features
Sound Amplifier. Available on Android 6.0 and above, this feature uses your phone's microphone (or connected headphones) to boost and filter sounds around you in real time — particularly useful in noisy environments.
Live Transcribe. Developed by Google, this app converts speech to text in real time, using the phone's microphone. It works across 80+ languages and works without an internet connection for several languages. It can also detect environmental sounds like applause, music, or alarms.
Hearing Aid Compatibility. Android 10 and above supports the Bluetooth LE Audio standard, which enables low-latency, direct connections between hearing aids and Android phones without additional adapters.
Third-Party Apps Worth Knowing
NIOSH SLM (Sound Level Meter). A free app from the CDC's National Institute for Occupational Safety and Health that accurately measures decibel levels in your environment — useful for assessing whether a workplace or venue poses a hearing risk.
Ava. A captioning app designed for group conversations. Everyone in the conversation downloads the app, and spoken words are converted to text in real time on each participant's screen — significantly improving accessibility in meetings and group settings.
Roger Voice. Provides real-time captions for phone calls — particularly useful when audio quality is poor or when a caller speaks quickly.
Tip: If you wear Soundbright's Discovery or Horizon Pro hearing aids, they connect directly to your smartphone via Bluetooth — letting you control volume, switch profiles, and stream audio from any app directly to your hearing aids.
