The harmonics plus noise model (HNM) has been used for prosodic speech signal modifications in high-quality environments in recent decades. Such speech modification techniques allow Text-To-Speech systems to generate more expressive synthesis without requiring extensive corpora resources. A more expressive synthesis can improve the user experience with(More)
It is known that voice quality plays an important role in expressive speech. In this paper, we present a methodology for modifying vocal effort level, which can be applied by text-to-speech (TTS) systems to provide the flexibility needed to improve the naturalness of synthesized speech. This extends previous work using low order Linear Prediction(More)
