Product Description
Description:
The reSpeaker 2-Mics Pi HAT is the voice user interface for Raspberry Pi Series, which has been equipped with 2 analogue microphones and TLV320AIC3104 Audio Codec for high-definition voice capture. Attached with NLU software algorithms and noise reduction algorithms, it has the abilities of Voice Activity Detection, Direction of Arrival, and Key Word Spotting, widely used in Voice Interaction applications. Using this dual-microphone expansion board designed for AI and voice applications, you can build a powerful and flexible voice product that integrates Amazon Alexa Voice Service, Google Assistant, and so on.
There are analogue microphones mounted on each corner of the square reSpeaker to receive audio data around them and transmit it to the codec. The codec integrates synchronized ADCs with a mic boost amplifier to deliver valid channel data to the Raspberry Pi/Pi Zero, where it transits them over I2S ports in standard I2S or PCM format, along with a single port in TDM format. 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 voice-based remote control cars, voice user interface, keyword wake up, and so on. Since the audio data transmitted may contain noise as well, the reSpeaker comes with the functions of Auto Echo Cancellation (AEC), Beamforming, WebRTC Noise Suppression (NS), and Automatic Gain Control (AGC) to reduce noise and provide better audio data to the Raspberry Pi.
