Playing remote audio (from Google Translate) in HTML5 on a server
提问by TomTasche
I'm trying to use text-to-speech on a website using HTML5 and Google Translate.
我正在尝试在使用 HTML5 和 Google 翻译的网站上使用文本到语音转换。
Getting speech from Google is as easy as a GET request to: http://translate.google.com/translate_tts?tl=en&q=hello
从 Google 获取语音就像向以下地址发送 GET 请求一样简单：http: //translate.google.com/translate_tts?tl=en&q=hello
In order to play that file I'm using the audio-tag:
为了播放该文件，我使用了音频标签：
<audio id="speech" src="http://translate.google.com/translate_tts?tl=en&q=hello" controls="controls" autoplay="autoplay">Your browser does not support the audio element.</audio>
<audio id="speech" src="http://translate.google.com/translate_tts?tl=en&q=hello" controls="controls" autoplay="autoplay">Your browser does not support the audio element.</audio>
That works perfectly when I try to open the html file locally using Chrome 11, but doesn't work at all when I open the html from my server... It just doesn't do anything (the play button flashes for a second, but nothing happens).
当我尝试使用 Chrome 11 在本地打开 html 文件时，这非常有效，但是当我从服务器打开 html 时根本不起作用......它什么也没做（播放按钮闪烁一秒钟，但没有任何反应）。
You can find the file here: http://www.announcify.com/chrome/background.html
您可以在此处找到该文件：http: //www.announcify.com/chrome/background.html
Any ideas? :)

Make sure your rel tags are set up correctly. There's a possibility that Google has a cross domain protection.
确保您的 rel 标签设置正确。谷歌可能有跨域保护。

NodeJS equivalent for accepted answer (formulated in comments) is:
NodeJS 等效于接受的答案（在评论中制定）是：
app.route("/api/tts").get(function(req,res){
res.type('audio/mpeg');
var text = req.query.q;
var request = require('request');
var url = "https://translate.google.pl/translate_tts?ie=UTF-8&q=" + text + "&tl=en&total=1&idx=0&client=t&prev=input";
request.get(url).pipe(res);
});
Client should send url-encoded text as a query param q, e.g. host/api/tts?q=Hello
客户端应该发送 url 编码的文本作为查询参数 q，例如 host/api/tts?q=Hello
