The reSpeaker 2-Mics Pi HAT is the\u00a0<\/span>voice user interface<\/span><\/strong>\u00a0for Raspberry Pi Series, which has been equipped\u00a0<\/span>2 analogue microphones<\/span><\/strong>\u00a0<\/span>\u305d\u3057\u3066<\/span>\u00a0<\/span>TLV320AIC3104<\/strong><\/span><\/span>\u00a0Audio Codec<\/span><\/strong>\u00a0for high-definition voice capture. Attach with\u00a0<\/span>NLU software algorithms\u00a0<\/span><\/strong>\u305d\u3057\u3066<\/span>\u00a0noise reduction algorithms<\/span><\/strong>, it has the abilities of Voice Activity Detection, Direction of Arrival and Key Word Spotting, widely used in Voice Interaction applications.<\/span><\/p>\n

How does reSpeaker work?<\/span><\/strong><\/h3>\n

There are analogue microphones mounted on each corner of the square reSpeaker, to receive audio data around then transmit them to the codec. The codec integrates synchronized ADCs with mic boost amplifier, to deliver valid channel data to the Raspberry Pi\/ Pi Zero, where it transits them over I2S ports by standard I2S or PCM format, along with a single port by TDM format.<\/span><\/p>\n

<\/div>\n

The NLU algorithms will be applied to the Raspberry Pi once the audio data has arrived. The main functions include Voice Activity Detection(VAD), Direction of Arrival(DOA), and Key Word Spotting(WKS), suitable for various Voice Interaction applications such as\u00a0<\/span>voice-based remote control cars<\/span><\/strong>,\u00a0<\/span>voice user interface, keywords wake up<\/span><\/strong>\u00a0and so on.<\/span><\/p>\n

<\/p>\n

\n
\n

Since the audio data transmitted may contain the noise\u00a0as well, the reSpeaker comes with the functions of Auto Echo Cancellation (AEC), Beamforming, Webrtc Noise Suppression (NS), and\u00a0Automatic Gain Control\u00a0(AGC)\u00a0to reduce noise\u00a0and perform better audio data to the Raspberry Pi.<\/p>\n<\/div>\n<\/div>\n
