AI Hearing Assistant Pro

Important safety information

Use earphones or headphones. Using speakers can create acoustic feedback. This app cannot reliably remove your own voice from what the microphone captures.
Not a medical device. This is a prototype listening tool. It is not a certified hearing aid and does not replace an audiologist.
Stay aware. Do not use while driving or in situations where you need full environmental awareness.

Listening presets

Presets are listening preferences, not clinically prescribed hearing profiles.

Hearing settings

Tap to expand or collapse

Voice clarity Speech-frequency emphasis 0 dB

Boosts speech-range frequencies around 2.5 kHz. This is an equalizer preference, not speech separation.

Bass and treble Bass 0 dB Treble 0 dB

Frequency adjustment

Adjustable equalizer bands. Frequencies are labelled in Hz.

500 Hz 0 dB 1,000 Hz 0 dB 4,000 Hz 0 dB

Background noise Noise gate strength Low

The noise gate attenuates low-level background sounds. It does not remove all background noise.

Audio processing Echo cancellation Browser noise suppression Automatic gain control

These options use browser-native microphone processing. Actual availability depends on your browser, device, and microphone. The app reports what the browser actually applied.

Audio devices

Output device

Output selection uses setSinkId and requires browser support.

Microphone input

Changing the microphone requires restarting listening.

Advanced voice separation

Unavailable

Advanced voice separation unavailable.

This prototype does not include a speech-separation model. Ordinary echo cancellation cannot reliably separate your own voice from another person’s voice captured by the same microphone. A real separation model would need to be installed and initialised before this feature could be enabled.

Privacy and safety

This app does not record or upload your microphone audio.
