我想要实现的是与Web Speech API相同的实时脚本处理流程,但使用的是Google Cloud Speech API.

主要目标是使用gRPC协议通过带有Speech API的Electron应用程序转录实时录制.

这是我实现的简化版本:

const { desktopCapturer } = window.require('electron');
const speech = require('@google-cloud/speech');

const client = speech.v1({
    projectId: 'my_project_id',
    credentials: {
        client_email: 'my_client_email',
        private_key: 'my_private_key',
    },
});

desktopCapturer.getSources(
    { types: ['window', 'screen'] },
    (error, sources) => {
        navigator.mediaDevices
            .getUserMedia({
                audio: true,
            })
            .then((stream) => {
                let fileReader = new FileReader();
                let arrayBuffer;
                fileReader.onloadend = () => {
                    arrayBuffer = fileReader.result;
                    let speechStreaming = client.streamingRecognize({
                        config: {
                           encoding: speech.v1.types.RecognitionConfig.AudioEncoding.LINEAR16,
                           languageCode: 'en-US',
                           sampleRateHertz: 44100,
                        },
                        singleUtterance: …
