Overall I am impressed with the sound quality of the provided voices. Cloning of my own voice was straight forward process (under 80 seconds) and the ouput was eerily good. I was primarily testing the TTS capabilites of ePub and PDFs. Simple to upload the doc and generate the mp3. Some suggestions for finesse would include ease of changing the project name and better indication that the mp3 was completed. On screen, it looked like it was perpetually generating, but thankfully - I received an email that it was finished. There is still a lot of rich functionality to further explore - but so far it meets my primary use-case. Thanks team!
