I've a problem with google TTS api. Well, I think that with the api everything it is ok because if I use the path of my desktop and I run the app in the simulator, it create the file with the mp3. The problem is I can't reproduce it. I have no error, but I can't ear nothing. I use AVaudioPlayer. This is the code I use:
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:@"file.mp3"];
NSString *text = @"You are one chromosome away from being a potato.";
NSString *urlString = [NSString stringWithFormat:@"http://www.translate.google.com/translate_tts?tl=en&q=%@",text];
NSURL *url = [NSURL URLWithString:[urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSMutableURLRequest* request = [[[NSMutableURLRequest alloc] initWithURL:url] autorelease];
[request setValue:@"Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:2.0.1) Gecko/20100101 Firefox/4.0.1" forHTTPHeaderField:@"User-Agent"];
NSURLResponse* response = nil;
NSError* error = nil;
NSData* data = [NSURLConnection sendSynchronousRequest:request
returningResponse:&response
error:&error];
[data writeToFile:path atomically:YES];
AVAudioPlayer *player;
NSError *err;
if ([[NSFileManager defaultManager] fileExistsAtPath:path])
{
player = [[AVAudioPlayer alloc] initWithContentsOfURL:
[NSURL fileURLWithPath:path] error:&err];
player.volume = 0.4f;
[player prepareToPlay];
[player setNumberOfLoops:0];
[player play];
}
I get this code from another stackoverflow question : Text-to-speech on iPhone
