The process began with a real human voice actor. This voice talent spent dozens of hours in a professional recording studio reading a massive, phonetically balanced corpus of text. The text included everything from news articles to random string sequences to capture every possible sound transition in the English language. 2. Slicing the Audio (Phonemes and Diphones)
