    Hi everyone,
    I am using OpenEars to recognise what’s user saying and AVSpeechSynthesizer to say different messages to user.
    The thing is that AVSpeechSynthesizer output audio quality is dropping dramatically when OpenEars speech recognition is on. When I turn off speech recognition audio quality is back to normal.
    I can’t figure out why is that happening. Do you have any ideas?

    Welcome,

    This is a known issue due to PocketsphinxController requiring the PlayAndRecord audio session with a particular sample rate. You can read about it in the FAQ and in other threads on issues of audio coexistence. I’m currently researching improvements to this but it’s fairly complex.
