Voice Control enhancement for smart loudspeakers

Reference number
Coordinator LIMES AUDIO AB
Funding from Vinnova SEK 1 200 446
Project duration August 2016 - July 2018
Status Completed
Venture The strategic innovation programme Electronic Components and Systems:

Purpose and goal

The purpose of the project is to develop speech enhancement algorithms that suppress noise and reverberation, for improved voice control of smart consumer electronics, such as smart loudspeakers. The goal is to improve the voice control, specifically in acoustically challenging situations, such as over long distances and in noisy environments.

Expected results and effects

A successful project will mean more robust voice control with increased reliability. This will make the voice control interface appear better and more natural, which in turn will reduce user frustration. The expected result is that a user shall be able to speak to the developed solution, also in challenging acoustic environments, in the same way as if s/he would be speaking to another person.

Planned approach and implementation

Limes Audio has developed the signal processing software TrueVoice, which is world leading in the field of voice communication. This software will be adapted for voice control front-end processing. The project will begin with a exhaustive evaluation of the existing TrueVoice software together with an existing voice control software from a third party. Thereafter follows adaptation of sub-blocks in the current TrueVoice solution, specifically for improved voice control performance, development of new sub-blocks, system integration and finally optimization and verification.
