What is Audio Front End ?

Audio Front End is the combination of multiple technologies created to evaluate and improve the signal quality of an audio source. Dividing sound into different criterias such as signal-to-noise ratio, echo/reverb level or signal fiability makes it possible to apply specific filters to the signal so that its quality is perfect for voice-based use cases.

Some use cases made real with audio front end solutions

Audio Front End is made for companies and developers that plan to develop voice-based features in specific fields with environments property that requires to improve the recorder audio signals.

Noise Cancellation

For industries or outdoor areas where parasite noise can interfere with the signal quality, reducing the reliability of the voice commands.

Echo Reduction

Used for use case that features far-field microphone use where echo and reverd can drastically modify the audio signal composition.

Audio Reliability

Using MOS evaluation through machine learning models to evaluate the overall signal quality and reliability.

A technology available inside the Voice Development Kit

1. Stream or upload your audio files

Gather different audio files or record them directly through the VDK with multiple setups (microphones, range, far or close field, ambiant noise…) to start working.

2. Evaluate your audio signal quality

Our Audio Front End solution will give scoring to your audio file regarding the criterias you chose (signal to noise ratio, echo level, MOS scoring…).

3. Apply filters to improve your recordings

For low-scoring audio files, find the good mix of audio filters (noise cancellation, echo reduction…) to find chich setup you need for your use case.
