Here are a few things you can do to ensure a production-ready Overdub voice with crisp fidelity, and natural expressiveness.
Improve your recording conditions
In case you missed it the first time around: Your training data should be recorded in a quiet, acoustically “dead” room, and you should be using an external microphone.
Record more training audio
While Overdub voices can be trained with as little as 10 minutes of audio, we recommend at least 30 minutes. The likelihood of a production-ready voice increases as you increase your training data volume, all the way up to 90 minutes.
