Microphone stays on after stop() and close().

[mazo20]

I am building an app where I use both speech recognition and text-to-speech. However, I have encountered an error where the microphone used for speech recognition is being kept on even after I stop the recognition with stop() or close() or if it completes on its own. If the mic is kept on I cannot play any sounds and hence the text-to-speech doesn't work after I use speech recognition.

This is because the plugin sets the audioSession category to "record":

https://github.com/rxlabz/speech_recognition/blob/d527d13d16c2a9cd001bf14a4372ec74c69f72b2/ios/Classes/SwiftSpeechRecognitionPlugin.swift#L111

and this doesn't allow audio playback, which is why you hear nothing.

Two options to fix this: 1) After speech recognition is invoked, manually set the category to playback in your text-to-speech code. 2) Fork the speech_recognition plugin to set the category to playAndRecord
