Hi, it’s a big library thanks!

How can I make listen all the time (without using a timer in sr_Results event)

No. You cant use this for continuous listening. Search for continuous speech recognition library.

Tried this in my music app. Wanted to be able to shout Music Skip, Music Play, Music Pause, etc

Problem is it is always beeping and if I turn off the beeps the music gets paused.

Tried to change the code to not mute the music volume but then it beeps.

B4X:

Public Sub StartListening(LANGUAGE As String, ONLY_RETURN_LANGUAGE_PREFERENCE As Boolean, PARTIAL_RESULTS As Boolean,PREFER_OFFLINE As Boolean)
   RecognizerIntent.Initialize("android.speech.action.RECOGNIZE_SPEECH",Null)
   RecognizerIntent.PutExtra("android.speech.extra.LANGUAGE_PREFERENCE",LANGUAGE)
   If ONLY_RETURN_LANGUAGE_PREFERENCE Then RecognizerIntent.PutExtra("android.speech.extra.ONLY_RETURN_LANGUAGE_PREFERENCE",LANGUAGE)
   RecognizerIntent.PutExtra("calling_package",Application.PackageName)
   RecognizerIntent.PutExtra("android.speech.extra.LANGUAGE_MODEL","free_form")
   RecognizerIntent.PutExtra("android.speech.extra.PARTIAL_RESULTS",PARTIAL_RESULTS)
   RecognizerIntent.PutExtra("android.speech.extra.PREFER_OFFLINE",PREFER_OFFLINE)
   
   
   If nosound Then
       Dim p As Phone
       volA = p.GetVolume(p.VOLUME_ALARM)
       volM = p.GetVolume(p.VOLUME_MUSIC)
       volN = p.GetVolume(p.VOLUME_NOTIFICATION)
       volR = p.GetVolume(p.VOLUME_RING)
       volS = p.GetVolume(p.VOLUME_SYSTEM)
       volV = p.GetVolume(p.VOLUME_VOICE_CALL)
       
       p.setVolume(p.VOLUME_ALARM,           0,   False)
'       p.setVolume(p.VOLUME_MUSIC,           0,   False)  - comment out to not stop music from playing
       p.setVolume(p.VOLUME_NOTIFICATION,   0,   False)
       p.setVolume(p.VOLUME_RING,           0,   False)
       p.setVolume(p.VOLUME_SYSTEM,       0,   False)
       p.setVolume(p.VOLUME_VOICE_CALL,   0,   False)
   End If
   
   JO.RunMethod("startListening",Array(RecognizerIntent))
End Sub

A shame that we can't change the underling library to not do the beeps, because it works real well.
Music playing does not seem to effect the listening for commands

Brandsum · Oct 19, 2019

I dont think that you listen for voice input while playing something without the beep sound.

Robert Valentino · Oct 19, 2019

OK, but it seems to work fine. The playing sound is coming out the ear plug jack into a amp and playing over external speakers.

Brandsum · Oct 19, 2019

*without the beep sound.

Brandsum · Oct 19, 2019

Because Android SpeechRecognizer use music channel to play the beep sound.

Robert Valentino · Oct 19, 2019

Found this on stack overflow: https://stackoverflow.com/questions...p-sound-without-muting-music-from-mediaplayer

Just not sure how to try it.

Brandsum · Oct 20, 2019

Thats a different thing. Check this

Hi! Great library, thank you!
Is there a way to get the raw audio?

Brandsum · Oct 24, 2019

I don't think so.

KZero · Oct 29, 2019

language is always English , i tried ar-SA , it , fr

all returning english

JohnC · Dec 20, 2019

For the "LANGUAGE" parameter, if I specify a null ("") string, will this just set the preferred language of the results to the devices default language?

If not, how can I return results in the language of the user's device?

JohnC · Dec 28, 2019

Can an event be added to this library that will trigger when the device is fully ready and is now "listening" for speech?

(The BeginningofSpeech event is an event that triggers *after* someone starts talking - this is not what I am looking for)

What I am looking for is an event that triggers when the speech engine first starts to *listen*. I need such an event because on slower devices, especially when using the online mode, it may take a few seconds to fully initialize the SR engine before it's ready to start "hearing" words. So without this event (that I plan on displaying "Say Something" when this event triggers), the user may not know the SR engine is not yet listening and may miss the first couple of words the user said before it started to listen.

No

Here is how you can get the user's device language.

Get user's device language string:

Sub Get_Language As String
    Dim jo As JavaObject
    Return jo.InitializeStatic("java.util.Locale").RunMethod("getDefault", Null)
End Sub

Yes. Its possible. I will post an update today.

Thank you for adding the "ReadyForSpeech" event so quickly - works great!

GeorgManfred · Feb 2, 2020

Many thanks for this.
I was looking for a way to use offline voice input to control my SmartHome center. Now I can do that well.

Please post error messages as text.

See the documentation of Phone.SetVolume. It will throw an exception if the device is in DnD mode. You can either catch this error or if it is important to set the volume, follow this path: https://www.b4x.com/android/forum/t...sturb-mode-programmatically.82794/post-524483
