Picovoice Demo on ReSpeaker
Picovoice has integrated and tested its end-to-end voice platform on ReSpeaker 4-mic. ReSpeaker mics provide a clean and high-fidelity stream of audio required for voice recognition. Additionally, Picovoice has open-sourced a demo that can run on any Raspberry Pi connected to a ReSpeaker microphone. The demo enables controlling LEDs on the microphone array with voice commands such as:
Picovoice, turn on the lights.
Picovoice, set the lights to blue.
