文本到node.js上的音频文件 [英] text to audio file on node.js
问题描述
我正在寻找一种优化的合法方法，可以从nodejs上的文本创建音频文件.
Im looking for an optimized legal way to create an audio file from text on nodejs.
现在我看到5个变体:
1)向Google发送简单的hhtp请求，将文本转换为api. 这个变体不好，因为每个请求都需要生成的令牌 例如'tk:729008.879154' 没有这个，它可能会失败.除此之外，此选项为非法".
1) simple hhtp request to google translate text-to-sppeach api. This variant isn't good, because each request demands on generated token e.g. 'tk:729008.879154' Without this it can fail. Besides that, this option is 'illegal'.
2)谷歌向http请求从控制台浏览器"翻译文本到语音合成api- puppeteer
2) http request to google translate text-to-sppeach api from 'console browser' - puppeteer
有没有一种方法可以生成正确的令牌密钥以使该请求合法"?
Is there a way to generate right token key to make this request 'legal'?
3)在puppeteer中使用Web Speech Api获取二进制数据并将其保存到文件吗? 还是有一种使用Chromium/Chrome源代码的方法?
3) use Web Speech Api in puppeteer to get binary data and save it to file? Or is there a way to work with Chromium/Chrome source code ?
4)在具有nodejs的计算机上使用任何其他技术/语言库，并使用js作为解释器来调用此技术/程序中的命令. 有什么想法吗?
4) Using any other technology/language library on machine with nodejs and to use js as interpreter to call commands in this technology/programm. Any ideas?
5)是否有任何支持不同语言的免费公共api(dream api)?
5) Any free public api with different languages support (dream api)?
任何建议将不胜感激.
推荐答案
一种可能的方法是包装eSpeak命令行工具(Windows和Linux) http://espeak.sourceforge.net/.然后，您可以使用Node.js包装.
One possible approach is to wrap the eSpeak command line tool (Windows & Linux) http://espeak.sourceforge.net/. You can then wrap with Node.js.
const { exec } = require('child_process');
var outputFile = process.argv[2] || "output.wav";
var voice = process.argv[3] || "en-uk-north";
var text = process.argv[4] || "hello there buddy";
var command = `espeak.exe -v ${voice} -w ${outputFile} "${text}"`;
exec(command, (err, stdout, stderr) => {
if (err) {
console.log("Error occurred: ", err);
return;
}
});
这会产生相当低的质量输出.
This gives a fairly low quality output.
我还使用了Bing Speech API，并且输出非常好，我创建了一个Node.js示例.您将需要注册一个API密钥，但这非常简单(您可以
I've also played with the Bing Speech API and the output is very good, I've created a Node.js example. You would need to sign up for an API key but this is very easy (you to to https://azure.microsoft.com/en-us/try/cognitive-services/ and select "Speech").
const key = 'your api key here';
function synthesizeSpeech(apiKey)
{
const fs = require('fs');
const request = require('request');
const xmlbuilder = require('xmlbuilder');
const text = process.argv[2] || "The fault, dear Brutus, is not in our stars, But in ourselves, that we are underlings.";
const outputFile = process.argv[3] || "speech.wav";
var ssml_doc = xmlbuilder.create('speak')
.att('version', '1.0')
.att('xml:lang', 'en-au')
.ele('voice')
.att('xml:lang', 'en-au')
.att('xml:gender', 'Female')
.att('name', 'Microsoft Server Speech Text to Speech Voice (en-AU, HayleyRUS)')
.txt(text)
.end();
var post_speak_data = ssml_doc.toString();
console.log('Synthesizing speech: ', text);
request.post({
url: 'https://api.cognitive.microsoft.com/sts/v1.0/issueToken',
headers: {
'Ocp-Apim-Subscription-Key' : apiKey
}
}, function (err, resp, access_token) {
if (err || resp.statusCode != 200) {
console.log(err, resp.body);
} else {
try {
request.post({
url: 'https://speech.platform.bing.com/synthesize',
body: post_speak_data,
headers: {
'content-type' : 'application/ssml+xml',
'X-Microsoft-OutputFormat' : 'riff-16khz-16bit-mono-pcm',
'Authorization': 'Bearer ' + access_token,
'X-Search-AppId': '9FCF779F0EFB4E8E8D293EEC544221E9',
'X-Search-ClientID': '0A13B7717D0349E683C00A6AEA9E8B6D',
'User-Agent': 'Node.js-Demo'
},
encoding: null
}, function (err, resp, data) {
if (err || resp.statusCode != 200) {
console.log(err, resp.body);
} else {
try {
console.log('Saving output to file: ', outputFile);
fs.writeFileSync(outputFile, data);
} catch (e) {
console.log(e.message);
}
}
});
} catch (e) {
console.log(e.message);
}
}
});
}
synthesizeSpeech(key);
也可以在此处查看MARY项目: http://mary.dfki.de/，是可以安装的开源服务器，声音输出非常好，您可以从node.js调用服务器.
Also check out the MARY project here: http://mary.dfki.de/, this is an open source server that you can install, the voice output is very good, you could make calls to the server from node.js.
如果您安装Mary语音引擎(非常简单):
If you install the Mary Speech engine (quite easy):
"use strict";
const fs = require('fs');
const request = require('request');
const text = process.argv[2] || "The fault, dear Brutus, is not in our stars, But in ourselves, that we are underlings.";
const outputFile = process.argv[3] || "speech_mary_output.wav";
const options = {
url: `http://localhost:59125/process?INPUT_TEXT=${text}!&INPUT_TYPE=TEXT&OUTPUT_TYPE=AUDIO&AUDIO=WAVE_FILE&LOCALE=en_US&VOICE=cmu-slt-hsmm`,
encoding: null // Binary data.
}
console.log('Synthesizing speech (using Mary engine): ', text);
console.log('Calling: ', options.url);
request.get(options, function (err, resp, data) {
if (err || resp.statusCode != 200) {
console.log(err, resp.body);
} else {
try {
console.log(`Saving output to file: ${outputFile}, length: ${data.length} byte(s)`);
fs.writeFileSync(outputFile, data, { encoding: 'binary'});
} catch (e) {
console.log(e.message);
}
}
});
这将为您合成语音.无需API密钥！
This will synthesize speech for you. No API key required!
