如何在 Windows 电子应用程序中授予音频权限？

问题描述 投票：0回答：3

我正在尝试在电子应用程序中实现语音识别。该解决方案适用于 chrome 浏览器，但不适用于 electron。该应用程序立即停止收听 - 它可能没有麦克风许可。如何授予权限？

index.js

const electron = require('electron');
const url = require('url');
const path = require('path');

const { app, BrowserWindow, ipcMain } = electron;

let mainWindow;


ipcMain.on('close-me', (evt, arg) => {
    app.quit()
})

app.on('ready', () => {
    mainWindow = new BrowserWindow({
        transparent: true,
        frame: false,
        webPreferences: {
            nodeIntegration: true,
            webviewTag: true
        }
    });


    mainWindow.loadURL(url.format({
        pathname: path.join(__dirname, 'web/index.html'),
        protocol: 'file',
        slashes: true
    }));

    mainWindow.webContents.openDevTools();
    mainWindow.setFullScreen(true);


});

index.html

<!doctype html>
<html lang="en">
<head>
    <title></title>
    <link rel="stylesheet" href="styles/style.css">
</head>

<body>
    <div class="container">

        <button id="rec"> rec</button>
        <button id="endrec"> end</button>

    </div>
    <script src="scripts/speech.js"></script>
</body>
</html>

speech.js

const SpeechRecognition = window.SpeechRecognition || window.webkitSpeechRecognition;
const recognition = new SpeechRecognition();
recognition.lang = 'pl-PL';
const rec = document.querySelector('#rec');
const endrec = document.querySelector('#endrec');

    recognition.onstart = function () {
        console.log('I started');
    }

    recognition.onend = function () {
        console.log('I finished');
    }

    recognition.onresult = function () {
        console.log('Take what I recorded');
        console.log(event);

        const current = event.resultIndex;
        const transcript = event.results[current][0].transcript;
        console.log(transcript);

    }

    rec.addEventListener('click', () => {
        recognition.start();
        console.log('You clicked me');
    })

    endrec.addEventListener('click', () => {
        recognition.stop();
    })

我也尝试过

的解决方案 
webview.addEventListener('permissionrequest', function (e) {
     if (e.permission === 'media') {
         e.request.allow();
    }
});

和

navigator.webkitGetUserMedia({ audio: true })

更新

我找到了停止识别的理由-错误-网络

我想你会想在你的会议上使用

setPermissionRequestHandler
，像这样：

const electron = require('electron');
const url = require('url');
const path = require('path');

const {
    app,
    BrowserWindow,
    ipcMain,
    session
} = electron;

let mainWindow;


ipcMain.on('close-me', (evt, arg) => {
    app.quit()
})

app.on('ready', () => {
    mainWindow = new BrowserWindow({
        transparent: true,
        frame: false,
        webPreferences: {
            nodeIntegration: true,
            webviewTag: true
        }
    });

    mainWindow.loadURL(url.format({
        pathname: path.join(__dirname, 'web/index.html'),
        protocol: 'file',
        slashes: true
    }));

    mainWindow.webContents.openDevTools();
    mainWindow.setFullScreen(true);

    session.fromPartition("default").setPermissionRequestHandler((webContents, permission, callback) => {
        let allowedPermissions = ["audioCapture"]; // Full list here: https://developer.chrome.com/extensions/declare_permissions#manifest

        if (allowedPermissions.includes(permission)) {
            callback(true); // Approve permission request
        } else {
            console.error(
                `The application tried to request permission for '${permission}'. This permission was not whitelisted and has been blocked.`
            );

            callback(false); // Deny
        }
    });
});

看来权限被命名为

desktopCapture
现在捕获音频。

我自己也遇到过类似的问题，发现谷歌没有为电子等基于 CLI 的应用程序提供 speechAPI。您最好的选择是使用Google Cloud Speech API或任何第三方API，例如Microsoft Cognitive Service。

你在 MacOS 上测试吗？我在我的 MBP 中遇到了类似的问题，下面的检查解决了这个问题 -

systemPreferences.askForMediaAccess(microphone)

有关其他详细信息，请参阅电子文档参考。
