AI POWERED SPEECH ENHANCEMENT API

2Hz Krisp API

Features

Voice Breakup Recovery

During calls when network conditions are bad our voice is being broken up and sounds annoying.

Krisp engine recovers these breakups by predicting the lost parts and filling them in.

The audio sounds better for playback as well as improves Speech Recognition.

Denoising

Krisp engine separates and removes background noise from audio and only leaves human voice in it.

The processed audio sounds better for human ear and as well as improves Speech Recognition results.

Bandwidth Expansion

Krisp engine converts lowband audio to wideband by predicting the higher frequencies of human voice and filling in.

The processed audio sounds richer (HD) for human ear and as well as improves Speech Recognition results when the Speech Recognition model is trained on HD voice.
