Summary of XMOS VocalFusion- Background Noise Not a Problem Anymore
XMOS introduced the VocalFusion XVF3500, a voice processor featuring true stereo-AEC support for far-field microphone arrays. This technology enables accurate voice recognition in noisy environments, supporting integration with Amazon Alexa. The device aims to solve challenges like accents and background noise, facilitating easier deployment of voice-activated features in commercial electronics.
Parts used in the VocalFusion XVF3500 Project:
- VocalFusion XVF3500 device
- VocalFusion 4-Mic Dev Kit
- VocalFusion XVF3000 device
- Far-field linear microphone array
- Amazon AVS (Alexa Voice Service) qualification
XMOS is one of the many companies that has ventured in voice recognition technology. They created the VocalFusion XVF3500 device, the first voice processor to have true stereo-AEC support in a far-field linear microphone array solution. Voice recognition is a relatively new technology for consumers which we came to know with Siri, google home, Alexa etc. However, this technology has been developed since 1950s with a very limited understanding of numbers. Nowadays, voice recognition software can answer all kind of questions, perform activities (such as calls, notes and web searches), and even answer to sarcastic questions. Experts predict that 50 % of all web searches will be made using voice by 2020.
Voice recognition is not only about not using keyboards, but also about security and usability. Thanks to software such as Siri people can now make phone calls in the car without even looking at their phone, play music and send messages. The biggest problem is accuracy specially when dealing with accents which the voice software may not be able to comprehend.
Speech recognition works by analyzing the sound, filtering what you say and digitalizing it into a form that the computer can read, and then analyzing it for meaning. It has become increasingly complex to program this kind of software because of language, dialects, accents, and phrasing. Also, background noise can easily throw off the interpretation of your speech.
At CES 2018, XMOS plans to display their new XVF3500 voice processor alongside the VocalFusion 4-Mic Dev Kit, which was the first far-field linear array solution to achieve Amazon AVS (Alexa voice service) qualification, delivering easy integration of Amazon Alexa into commercial and industrial electronics. The kit is based on the VocalFusion XVF3000 device which provides acoustic echo cancellation and advanced noise suppression. This will allow developers to build Alexa enabled products which will accelerate it’s deployment in new systems and new devices giving customers the ability to access Alexa from more places.
