【简介】
文本转语音可使用语音合成标记语言 (SSML) 将输入文本转换为类似人类的合成语音，本篇文档主要介绍了如何通过JavaScript 的语音SDK实现文本转换为语音的实践操作
【操作步骤】
一.配置语音 SDK集成环境
- 通过如下命令下载安装语音服务中的JavaScript SDK包
yarn add microsoft-cognitiveservices-speech-sdk
2.同时创建一个“yuyin“的目录以及一个”index.js"的文件（主要用于编写speech-sdk代码）
二.配置调试语音服务SDK
1.将以下代码复制到我们创建的index.js当中：
(function() {
"use strict";
var sdk = require("microsoft-cognitiveservices-speech-sdk");
var readline = require("readline");
var key = "YourSubscriptionKey";
var region = "YourServiceRegion";
var audioFile = "YourAudioFile.wav";
const speechConfig = sdk.SpeechConfig.fromSubscription(key, region);
const audioConfig = sdk.AudioConfig.fromAudioFileOutput(audioFile);
// The language of the voice that speaks.
speechConfig.speechSynthesisVoiceName = "en-US-JennyNeural";
// Create the speech synthesizer.
var synthesizer = new sdk.SpeechSynthesizer(speechConfig, audioConfig);
var rl = readline.createInterface({
input: process.stdin,
output: process.stdout
});
rl.question("Enter some text that you want to speak >\n> ", function (text) {
rl.close();
// Start the synthesizer and wait for a result.
synthesizer.speakTextAsync(text,
function (result) {
if (result.reason === sdk.ResultReason.SynthesizingAudioCompleted) {
console.log("synthesis finished.");
} else {
console.error("Speech synthesis canceled, " + result.errorDetails +
"\nDid you set the speech resource key and region values?");
}
synthesizer.close();
synthesizer = null;
},
function (err) {
console.trace("err - " + err);
synthesizer.close();
synthesizer = null;
});
console.log("Now synthesizing to: " + audioFile);
});
}());2.并在index.js 中，将 YourSubscriptionKey 替换为语音资源密钥，将 YourServiceRegion 替换为语音资源区域。
(function() {
"use strict";
var sdk = require("microsoft-cognitiveservices-speech-sdk");
var readline = require("readline");
var key = "e68024063a4f74be08902ac71329082e6"; // 语音资源密钥
var region = "EastUS"; // 语音资源地域
var audioFile = "YourAudioFile.wav"; // 语音资源文件
const speechConfig = sdk.SpeechConfig.fromSubscription(key, region);
const audioConfig = sdk.AudioConfig.fromAudioFileOutput(audioFile);
// The language of the voice that speaks.
speechConfig.speechSynthesisVoiceName = "en-US-JennyNeural";
// Create the speech synthesizer.
var synthesizer = new sdk.SpeechSynthesizer(speechConfig, audioConfig);
var rl = readline.createInterface({
input: process.stdin,
output: process.stdout
});
rl.question("Enter some text that you want to speak >\n> ", function (text) {
rl.close();
// Start the synthesizer and wait for a result.
synthesizer.speakTextAsync(text,
function (result) {
if (result.reason === sdk.ResultReason.SynthesizingAudioCompleted) {
console.log("synthesis finished.");
} else {
console.error("Speech synthesis canceled, " + result.errorDetails +
"\nDid you set the speech resource key and region values?");
}
synthesizer.close();
synthesizer = null;
},
function (err) {
console.trace("err - " + err);
synthesizer.close();
synthesizer = null;
});
console.log("Now synthesizing to: " + audioFile);
});
}());替换完毕以后如图所示
三.使用Node将语音合成到文件
1.在Vscode终端中，执行node程序，开始将语音合成到文件：
node.exe SpeechSynthesis.js执行完毕后，如下图所示：
2.我们按照如下步骤打开我们语音合成的文件
3.如下图所示，我们就可以直接打开听一下我们语音合成的文件，至此，我们就成功使用语音合成的SDK成功合成了一个语音文件了
