Speech recognition framework for iOS that supports Spanish [closed]

Question

Is there a speech to text framework for iOS that supports Spanish out of the box? Commercial or OS is ok.

Answer 1

There are a bunch of commercial IOS librariers for speech recognition. The names I keep hearing are Nuance, iSpeech, and Yapme. Each offers cloud speech recognition (off the device) and a client library and SDK to build into your app.

Nuance seems to support Spanish - http://blog.dragonmobileapps.com/2011/01/mobile-app-developer-dragon-mobile-sdk.html

...you can speech-enable your app for including US and UK English, European Spanish, European French, German, Italian and Japanese---with even more languages on tap for 2011!

and now Nuance gives developers free access - http://www.masshightech.com/stories/2011/09/26/daily13-Nuance-tweaks-mobile-dev-program-with-free-access-to-Dragon.html

iSpeech is likely to support Spanish - http://www.ispeech.org/developers/iphone

iSpeech's Mobile SDKs support 27 TTS and ASR (defined grammar) languages and 15 languages for free-form dictation voice recognition.

Yapme, sorry, I'm not sure - http://yapinc.com/speech-cloud.html

Answer 2

Take a look here: http://src.chromium.org/viewvc/chrome/trunk/src/content/browser/speech/

It's the Chrome Browser Speech to search...... you can do it in Objective-C. Try go google.com on chrome browser and if spanish is recognized, you win! :)

You can easily use:

- (void) SpeechFromGooglezzz {
  NSURL *url = [NSURL URLWithString:@"https://www.google.com/speech-api/v1/recognize?xjerr=1&client=chromium&lang=en-US"];

  ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
  NSString *filePath = [NSString stringWithFormat:@"%@%@", [[NSBundle mainBundle] resourcePath], @"tmpAudio.flac"];

  NSData *myData = [NSData dataWithContentsOfFile:filePath];
  [request addPostValue:myData forKey:@"Content"];
  [request addPostValue:@"audio/x-flac; rate=16000" forKey:@"Content-Type"];
  [request startSynchronous];

  NSLog(@"req: %@", [request responseString]);
}

Remember that you must recording a 16000 bitrate FLAC file! Or nothing!

Google responds with a json containing the words.

hope this helps.
