AI POWERED SPEECH ENHANCEMENT API

2Hz REST API

Features

Denoising

2Hz 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

2Hz 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.
