Hi !I'm currently working on a an Iphone app for people suffering of visual impairment. In order to get an input text, the app uses voice recognition.The app runs pretty well with Voice-Over activated, but when the user launch the voice recognition, Voice-Over output switch to the ear speaker (and that's normal I guess).What bothers me, is that when all the process is over, the output speaker doesn't switch back to main speaker even if I end all the processes.For the Voice recognition I created an instance of AVAudioEngine(), SFSpeechRecognizer(), SFSpeechAudioBufferRecognitionRequest() and SFSpeechRecognitionTask?. Then I tapped the request into the live input node and started the audioengine.After the user finished to speak, I called audioEngine.stop(), request.endAudio() and recognitionTask?.cancel() to stop everything and go back to a "normal" use of the app. Maybe I missed something when stoping everything, something about the live input node tapped : audioEngine.inputNode.installTap(onBus: 0, bufferSize: 1024, format: recordingFormat) { buffer, _ in self.request.append(buffer)}But I tried to removeTap(onBus: 0) but nothing changed. The output speaker comes back to normal only when I close the app or going to multitasking.I hope you could help me figure it out !ThanksRobin
