ReSpeaker 4-Mic Array for Raspberry Pi 樹莓派語音助理 AI人工智慧開發套件 支援 Pi-3B/4B

商品說明

ReSpeaker 4-Mic Array for Raspberry Pi 樹莓派 語音助理 人工智慧 開發套件

基於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。這意味著您可以藉助它構建一個集成Amazon Alexa語音服務，Google助手等，功能更強大，更靈活的語音產品。

區別於ReSpeaker 2-Mics Pi HAT，該板是基於AC108開發的，這是一款高度集成四通道ADC，具有用於高清晰度語音捕獲，I2S / TDM輸出，拾取3米半徑的聲音的語音設備。此外，這款4-Mics版本提供了超酷LED環，其中包含12個APA102可編程LED。就像Amazon Echo或Google協助一樣，使用4個麥克風和LED環，Raspberry Pi具有VAD（語音活動檢測） ），DOA（到達方向），KWS（關鍵字搜索），並通過LED環顯示方向燈功能。

注意：出貨清單不含樹莓派。Raspberry Pi 的 ReSpeaker 4-Mic Array 上沒有任何音頻輸出接口。只用於語音捕獲。你可以使用Raspberry Pi上的耳機插孔來輸出音頻。

ReSpeaker 4-Mic Array for Raspberry Pi

This product does not have audio output. If this is a requirement please consider the ReSpeaker 6-Mic Circular Array Kit For Raspberry Pi, the ReSpeaker 4-Mic Linear Array Kit for Raspberry Pi , or theReSpeaker Mic Array v2.0.

ReSpeaker 4-Mic Array for Raspberry Pi is a 4 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.
