I think desktop recognition is starting because you are using a shared desktop recognizer. You should use an inproc recognizer for your application only. you do this by instantiating a SpeechRecognitionEngine() in your application. Since you are using the dictation grammar and the desktop windows recognizer, I believe it can be trained by the speaker … Read more
The only solution that will for sure get around this issue is to use a 3rd party service. 4.1.1 and 4.2 both rely on a version of the speech recognition service that does not adhere to the documented behavior in that the service running it dies silently. If you do not wish to use a … Read more
A similar question was asked on Joel on Software a while back. You can use the System.Speech.Recognition namespace to do this…with some limitations. Add System.Speech (should be in the GAC) to your project. Here’s some sample code for a WinForms app: public partial class Form1 : Form { SpeechRecognizer rec = new SpeechRecognizer(); public Form1() … Read more
I think you would have to capture audio directly from the phone’s microphone and stream it to your own recognition service. The Google recognition APIs are built as an Intent that launches their own Recognition dialog and gives you back results. If you want continuous recognition without a UI, you’ll have to build that functionality … Read more
As pargat says, this will do it: intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, “en-US”); Also, your app can query for the list of supported languages by sending a RecognizerIntent.ACTION_GET_LANGUAGE_DETAILS ordered broadcast like so: Intent detailsIntent = new Intent(RecognizerIntent.ACTION_GET_LANGUAGE_DETAILS); sendOrderedBroadcast( detailsIntent, null, new LanguageDetailsChecker(), null, Activity.RESULT_OK, null, null); where LanguageDetailsChecker is something like this: public class LanguageDetailsChecker extends BroadcastReceiver { private … Read more
Perhaps you want to use the .net System.Speech namespace instead of SAPI? There is a very good article that was published a few years ago at http://msdn.microsoft.com/en-us/magazine/cc163663.aspx. It is probably the best introductory article I’ve found so far. It is a little out of date, but very helfpul. (The AppendResultKeyValue method was dropped after the … Read more
If you don’t have access to findpeaks, the basic premise behind how it works is that for each point in your signal, it searches a three element window that is centred at this point and checks to see whether the centre of this window is larger than the left and right element of this window. … Read more
I’ll rehash and update an answer from Speech recognition in C or Java or PHP?. This is by no means comprehensive, but it might be a start for you From watching these questions for few months, I’ve seen most developer choices break down like this: Windows folks – use the System.Speech features of .Net or … Read more
Thanks to Nikolay’s tip (see his answer above), I have developed the following code which works fine, and does not recognize words unless they’re on the list. You can copy and paste this directly over the main class in the PocketSphinxDemo code: public class PocketSphinxActivity extends Activity implements RecognitionListener { private static final String DIGITS_SEARCH … Read more
