English TTS model quality
During app testing, Emmanuel commented:
English TTS quality is lower than expected: it expected it to sound like https://erogol.github.io/ddc-samples/ -> can you check with Gerrit and Laurent which TTS model is being used and whether it's the right one?
In Comprise App Wizard there was option to specify TTS model and the text field was already prefilled with 'demo-en-tts'. Is there an updated model which we can use or is 'demo-en-tts' the best one?
