Automotive

Your in-car voice control system will be able to hear and understand you even when the cabin is awash with road noise, wind rush, the radio switched on and your passengers talking. The person at the other end of your hands-free telephone call will also be able to understand you.

SR performance is limited by real-world noise

Have you ever tried to use in-car voice recognition with bad road noise, the radio on, and the kids making noise in the back? AudioTelligence's nD technology makes all the difference between this working and not working.

Our Technology

We place a multi-microphone array in the car and, using AudioTelligence processing, we are able to separate the wanted voice from all of the different sources of noise. The clean voice signal is sent to the automatic speech recogniser in the car, which is then able to understand the instructions given to it. The separation is so good that it enables the speech recognition system to work even when many humans cannot understand what is being said.

Experiment on a Audi MMI 3G voice recognition commands detailing the spoken language capabilities of an in-car system.

The denoising process has a very large effect on reducing the WER compared to the noisy recordings. There is a consistent increase in the proportion of words correctly recognised, so we can conclude that the benefits do not purely derive from the reduction in insertion errors.
