I am using android.speech.SpeechRecognizer
and am having a problem where it makes a distinctive clang sound even after I've called its stopListening()
, cancel()
, and destroy()
methods.
Here is how I create and destroy the SpeechRecognizer
in MainActivity.kt
.
private fun startSpeechRecognition() {
Log.e(TAG, "At start of startSpeechRecognition()")
if (recognizer == null) {
recognizer = SpeechRecognizer.createSpeechRecognizer(this)
Log.e(TAG, "Creating new recognizer: $recognizer")
recognizer?.setRecognitionListener(Listener())
}
val intent = Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH)
intent.putExtra(
RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM
)
Log.e(TAG, "Starting listening")
recognizer?.startListening(intent)
}
private fun closeRecognizer() {
Log.e(TAG, "At start of closeRecognizer()")
recognizer?.run {
Log.e(TAG, "Stopping recognizer: $this")
stopListening()
cancel()
destroy()
recognizer = null
} ?: Log.e(TAG, "Recognizer already null")
}
Here is my log:
E/voice.assistan: Unknown bits set in runtime_flags: 0x8000
E/MainActivity: At start of closeRecognizer()
E/MainActivity: Recognizer already null

I am testing the code on a Pixel 2 running Android 10 and am compiling with minSdkVersion
21 and targetSdkVersion
28.
Can anyone tell me what I could be doing wrong or if there is a bug in the library?
I currently have a clumsy workaround where I mute the media audio stream after closing the recognizer.
