Abstract: Methods and systems for audio content production are provided whereby expressive speech is generated via acoustic elements extracted from human input. One of the inputs to the system is a human designating an intonation to be applied onto text-to-speech (TTS) generated synthetic speech. The human intonation includes the pitch contour and other acoustic features extracted from the speech. The system is designed to be used for, and is capable of speech generation, speech analysis, speech transformation, and speech re-synthesis at the acoustic level.
