Abstract
A method for generating synthetic speech can include identifying a recording of conversational speech and creating a transcription of the conversational speech. Using the transcription, rather than a predefined script, the recording can be analyzed and acoustic units extracted. Each acoustic unit can include a phoneme and/or a sub-phoneme. The acoustic units can be stored so that a concatenative text-to-speech engine can later splice the acoustic units together to produce synthetic speech.
