Ich versuche eine Spracherkennung ohne den Dialog zu programmieren. Für den ersten Anruf von SpeechRecognizer.startListening(recognizerIntent) funktioniert alles einwandfrei und ich bekomme Ergebnisse mit der erkannten Sprache String. Aber wenn ich die Erkennung zum zweiten Mal starten will, wird nur der Erkennungsstartton abgespielt und wenn ich aufhört zu sprechen, wird der Erkennungsende-Ton ausgegeben. Es werden keine Callback-Methoden wie onResults(), onRmsChanged oder onError usw. aufgerufen.SpeechRecognizer gibt Sound wieder, liefert aber keine Ergebnisse beim Aufruf von startListening()

Hat warum jemand eine Idee?
