Raspberry Pi Speak what you want !

1) Install mpg321

Tapez dans un terminal :

sudo apt-get install mpg321

2) Create a PHP file

Call it for exemple "speak.php" and put the following line: (don't forget the opening tags and PHP code closures)

exec('mpg321 "http://translate.google.com/translate_tts?tl=fr&q=Bonjour"');

So when will call the PHP file, the command line will be executed, and launch the mpg321 player mp3 file returns Google translate!

3) Add the www-data user to the audio group

If we do not add the user "www-data" to the audio group, our PHP command will not work, and we can not hear the Raspberry talk!

So type in a terminal:

sudo adduser www-data audio

4) Test !

Place this PHP file in the "/ var / www" of your Raspberry.

Then, type in the address of your browser Raspberry, followed by the name of your PHP file,

for example: http: //IP_RASP/speak.php (of course you need to be on the same network)

Normally, if your Raspberry is connected to a speaker / headphone and internet, you should hear "Hello"!

5) Raspberry say what you want

Just replace "hello" with a variable in your php file

if(isset($_GET['text']))
{
 exec('mpg321 "http://translate.google.com/translate_tts?tl=fr&q='.urlencode($_GET['text']).'"'); 
} 

So you can simply call the "http: //IP_RASP/speak.php text =?" Followed by the text you want your say Raspberry (encoded to a URL of course), so that the Raspberry expressed ! To encode the text to a URL (if you want to send accented text with spaces or special characters, ... use the "urlencode ()" in php or "encodeURIComponent ()" JavaScript!
