  • Methods and apparatus for speaker specific durational adaptation
    Patent number: 6813604
    Abstract: A text to speech system modeling durational characteristics of a target speaker is addressed herein. A body of target speaker training text is selected having maximum possible information about speaker specific characteristics. The body of target speaker training text is read by a target speaker to produce a target speaker training corpus. A previously generated source model reflecting characteristics of a source model is retrieved and the target speaker training corpus is processed to produce modification parameters reflecting differences between durational characteristics of the target speaker and those predicted by the source model. The modification parameters are applied to the source model to produce a target model. Text inputs are processed using the target model to produce speech outputs reflecting durational characteristics of the target speaker.
