As the title suggests I am using AVAudioEngine for SpeechRecognition input & AVAudioPlayer for sound output.
Apple says in this talk https://developer.apple.com/videos/play/wwdc2019/510 that the setVoiceProcessingEnabled function very usefully cancels the output from speaker to the mic. I set voiceProcessing on the Input and output nodes.
It seems to work however the volume is low, even when the system volume is turned up. Any solution to this would be much appreciated.
