Expanding on Chris  answer  I managed to reverse engineer the token generation process   The token for the request is based on the text and a global TKK variable set in the page script  These are hashed in JavaScript thus resulting in the tk param   Somewhere in the page script you will find something like this   TKK  403413    This is the amount of hours passed since epoch   The text is pumped in the following function  somewhat deobfuscated     x000D   x000D  var query    Hello person   x000D  var cM   function a    x000D      return function     x000D          return a x000D        x000D     x000D  var of        x000D  var dM   function a  b    x000D      for  var c   0  c  lt  b length -

In an update to Schahriar SaffarShargh s answer  Google has recently implemented a  Google abuse  feature  making it impossible to send just any regular old HTTP GET to a URL such as   http   translate google com translate tts tl en amp q Hello 20World  which worked just fine and dandy previously  Now  following such a link presents you with a CAPTCHA  This also affects HTTP GET requests out-of-browser  such as with cURL   because using that URL gives a redirect to the abuse protection page  the CAPTCHA    To start  you have to add the query parameter client to the request URL   http   translate google com translate tts tl en amp q Hello 20World amp client t  Google Translate sends  amp client t  so you should too   Before you make that HTTP request  make sure that you set the Referer header   Referer  http   translate google com   Evidently  the User-Agent header is also required  but interestingly enough it can be blank   User-Agent   Edit  NOTE - on some user-agents  such as Android 4 X  the custom User-Agent header is not sent  meaning that Google will not service the request  In order to solve that problem  I simply set the User-Agent to a valid one  such as stagefright 1 2  Linux Android 5 0   Use Wireshark to debug requests  as I did  if Google s servers are not responding  and ensure that these headers are being set properly in the GET  Google will respond with a 503 Service Unavailable if the request fails  followed by a redirect to the CAPTCHA page   This solution is a bit brittle  it is entirely possible that Google will change the way they handle these requests in the future  so in the end I would suggest asking Google to make a real API endpoint  free or paid  that we can use without feeling dirty for faking HTTP headers     Edit 2  For those interested  this cURL command should work perfectly fine to download an mp3 of Hello in English   curl  http   translate google com translate tts ie UTF-8 amp q Hello amp tl en amp client t  -H  Referer  http   translate google com   -H  User-Agent  stagefright 1 2  Linux Android 5 0    gt  google tts mp3   As you may notice  I have set both the Referer and User-Agent headers in the request  as well as added the client t parameter to the querystring  You may use https instead of http  your choice     Edit 3  Google now requires a token for each GET request  noted by tk in the querystring   Below is the revised cURL command that will correctly download a TTS mp3   curl  https   translate google com translate tts ie UTF-8 amp q hello amp tl en amp tk 995126 592330 amp client t  -H  user-agent  stagefright 1 2  Linux Android 5 0   -H  referer  https   translate google com    gt  google tts mp3  Notice the  amp tk 995126 592330 in the querystring  this is the new token  I obtained this token by pressing the speaker icon on translate google com and looking at the GET request  I simply added this querystring parameter to the previous cURL command  and it works   NOTE  obviously this solution is very frail  and breaks at the whim of the architects at Google who introduce new things like tokens required for the requests  This token may not work tomorrow  though I will check and report back     the point is  it is not wise to rely on this method  instead  one should turn to a commercial TTS solution  especially if using TTS in production   For further explanation of the token generation and what you might be able to do about it  see Boude s answer     If this solution breaks any time in the future  please leave a comment on this answer so that we can attempt to find a fix for it

Old answer   Try using this URL  http   translate google com translate tts tl en amp q Hello 20World It will automatically generate a wav file which you can easily get with an HTTP request through any  net programming   Edit   Ohh Google  you thought you could prevent people from using your wonderful service with flimsy http header verification   Here is a solution to get a response in multiple languages  I ll try to add more as we go    NodeJS     npm install  request  const fs   require  fs    const request   require  request    const text    Hello World    const options         url   https   translate google com translate tts ie UTF-8 amp q   encodeURIComponent text   amp tl en amp client tw-ob       headers             Referer    http   translate google com             User-Agent    stagefright 1 2  Linux Android 5 0            request options       pipe fs createWriteStream  tts mp3        Curl  curl  https   translate google com translate tts ie UTF-8 amp q Hello 20Everyone amp tl en amp client tw-ob  -H  Referer  http   translate google com   -H  User-Agent  stagefright 1 2  Linux Android 5 0    gt  google tts mp3   Note that the headers are based on  Chris Cirefice s example  if they stop working at some point I ll attempt to recreate conditions for this code to function  All credits for the current headers go to him and the wonderful tool that is WireShark   also thanks to Google for not patching this

Allright  so Google has introduces tokens  see the tk parameter in the new url  and the old solution doesn t seem to work  I ve found an alternative - which I even think is better-sounding  and has more voices  The command isn t pretty  but it works  Please note that this is for testing purposes only  I use it for a little domotica project  and use the real version from acapella-group if you re planning on using this commercially   curl   curl --data  MyLanguages sonid10 amp MySelectedVoice Sharon amp MyTextForTTS Hello 20World amp t 1 amp SendToVaaS    http   www acapela-group com demo-tts DemoHTML5Form V2 php    grep -o  http  mp3    gt  tts output mp3   Some of the supported voices are    Sharon Ella  genuine child voice  EmilioEnglish  genuine child voice  Josh  genuine child voice  Karen Kenny  artificial child voice  Laura Micah Nelly  artificial child voice  Rod Ryan Saul Scott  genuine teenager voice  Tracy ValeriaEnglish  genuine child voice  Will WillBadGuy  emotive voice  WillFromAfar  emotive voice  WillHappy  emotive voice  WillLittleCreature  emotive voice  WillOldMan  emotive voice  WillSad  emotive voice  WillUpClose  emotive voice    It also supports multiple languages and more voices - for that I refer you to their website  http   www acapela-group com
