Description

ReSpeaker 4-Mic Array for Raspberry Pi is a quad-microphone expansion board for Raspberry Pi designed for AI and voice applications. This means that you can build a more powerful and flexible voice product that integrates Amazon Alexa Voice Service, Google Assistant, and so on.


Different from ReSpeaker 2-Mics Pi HAT, this board is developed based on AC108, a highly integrated quad-channel ADC with I2S/TDM output transition for high definition voice capture. Besides, this 4-Mics version provides a super cool LED ring, which contains 12 APA102 programmable LEDs. With that 4 microphones and the LED ring, Raspberry Pi would have ability to do VAD(Voice Activity Detection), estimate DOA(Direction of Arrival) and show the direction via LED ring, just like Amazon Echo or Google Home.


Note

Please note that the package does not contain Raspberry Pi.


Features

  • Raspberry Pi compatible(Support Raspberry Pi Zero and Zero W, Raspberry Pi B+, Raspberry Pi 2 B and Raspberry Pi 3 B)

  • 4 Microphones

  • 3 meters radius voice capture

  • 2 Grove Interfaces

  • 12 APA102 User LEDs

  • Software Algorithm: VAD(Voice Activity Detection), DOA(Direction of Arrival) and KWS(Keyword Search)


Note

Please note that there are no any audio output interfaces on ReSpeaker 4-Mic Array for Raspberry Pi. It is only for voice capture. And you could use the headphone jack on Raspberry Pi for audio output.

描述

Raspberry Pi的ReSpeaker 4-Mic陣列是一款適用於AI和語音應用的Raspberry Pi的四通道麥克風擴展板。這意味著您可以構建一個功能更強大,靈活的語音產品,集成Amazon Amazona語音服務,Google助手等。

 

ReSpeaker 2-Mics Pi HAT不同 ,該板是基於AC108開發的,AC108是高度集成的四通道ADC,具有I2S / TDM輸出轉換,用於高清晰度語音捕獲。此外,這款4-Mics版本提供了超酷的LED環,其中包含12個APA102可編程LED。使用4個麥克風和LED環,Raspberry Pi將有能力進行VAD(語音活動檢測),估計DOA(到達方向),並通過LED環顯示方向,就像Amazon Echo或Google Home一樣。

 

注意

請注意,包裝不包含Raspberry Pi。

 

特徵

  • Raspberry Pi兼容(支持Raspberry Pi零和零W,Raspberry Pi B +,Raspberry Pi 2 B和Raspberry Pi 3 B)

  • 4個麥克風

  • 3米半徑的語音捕捉

  • 2 Grove接口

  • 12 APA102用戶LED

  • 軟件算法:VAD(語音活動檢測),DOA(到達方向)和KWS(關鍵詞搜索)

 

注意

請注意,Raspberry Pi的ReSpeaker 4-Mic Array沒有任何音頻輸出接口。它只用於語音捕獲。您可以使用Raspberry Pi上的耳機插孔進行音頻輸出。
