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.

  • 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.


Here is a video from Parvinder Yadav, it teaches how to use ReSpeaker 4-Mic Array for Raspberry Pi  to make google assistant. We really appreciate Parvinder's contribution to the community and hope this video can be a good help for you.

描述

ReSpeaker 4-麥克風陣列覆盆子 pi 是一個四麥克風擴展板的覆盆子 pi 設計的 AI 和語音應用。這意味著你可以建立一個更強大和靈活的語音產品, 集成亞馬遜 Alexa 的語音服務, 谷歌助手, 等等。


不同于ReSpeaker 2-麥克風的 Pi HAT, 該板是基於 AC108, 一個高度集成的四通道 ADC 與 I2S/TDM 輸出轉換為高清晰度語音捕獲開發。此外, 這4多麥克風版本提供了一個超酷的 led 環, 其中包含 12 APA102 可程式設計 led。與那4話筒和 led 圓環, 樹莓 Pi 將有能力做協助工具 (聲音活動檢測), 估計 DOA (到達的方向) 和顯示方向通過 LED 圓環, 象亞馬遜回聲或谷歌家。


注意

  • 請注意, 包裝不包含覆盆子 Pi。

  • 請注意, 沒有任何音訊輸出介面的 ReSpeaker 4-麥克風陣列的覆盆子 Pi。它只用于語音捕獲。你可以使用在覆盆子 Pi 耳機插座音訊輸出。


這裡是一個視頻從 Parvinder 亞達夫, 它教如何使用 ReSpeaker 4 麥克風陣列的覆盆子 Pi, 使谷歌助理。我們非常感謝 Parvinder 對社會的貢獻, 希望這個視頻能對你有很好的説明。
