- Evaluation board based on xCORE XVF3500 voice processor
- 4-Mic linear array with 33mm spacing
- True stereo-AEC
- Exceptional far-field voice capture with advanced voice DSP
- Qualified by Amazon for the Alexa Voice Service
VocalFusion Stereo Kit for Amazon AVS
VocalFusion Stereo Dev Kit for Amazon AVS
The kit features a compact four-microphone linear array, that enables developers and OEMs to add far-field voice capture to stereo consumer electronics and IoT products. The linear design is optimised for integration into set-top boxes, TVs, soundbars, digital media adaptors and other stereo audio and visual consumer electronics.
The voice signals are captured by the microphone array even in noisy environments, enabling commands to be accurately processed and passed to the Alexa client running on a system processor.
