I'm not sure if this is a Pleco issue or a Google issue. My app is set to use Google's Speech Services TTS engine, which has several voice options. I want to use Voice IV, which is what I have selected under Audio > System TTS Settings > Preferred engine settings > Install voice data > Chinese (China) > Voice IV. However, when using the file reader's TTS service, it seems to default back to Voice I. Did I miss an extra setting somewhere to use it for the file reader?
