问题描述
您好，我想在Google Home上制作自定义的api。
方法是语音转文本（stt）->自然语言处理（NLP）->使用IP端口控制我的智能灯。
所以，我正在测试Microphonestream.js。但是，我遇到了错误。
**Listening,press Ctrl+C to stop.
sox has exited with error code 1.
Enable debugging with the environment variable DEBUG=record.**
'use strict';
/**
* Note: Correct microphone settings is required: check enclosed link,and make
* sure the following conditions are met:
* 1. SoX must be installed and available in your $PATH- it can be found here:
* http://sox.sourceforge.net/
* 2. Microphone must be working
* 3. Encoding,sampleRateHertz,and # of channels must match header of audio file you're
* recording to.
* 4. Get Node-Record-lpcm16 https://www.npmjs.com/package/node-record-lpcm16
* More Info: https://cloud.google.com/speech-to-text/docs/streaming-recognize
