Surgery of Speech Synthesis Models to Overcome the Scarcity of Training Data
Advances in Speech and Language Technologies for Iberian LanguagesPages 73–83https://doi.org/10.1007/978-3-319-49169-1_8AbstractIn a previous work we developed an HMM-based TTS system for a Basque dialect spoken in southern France. We observed that French words, frequent in daily conversations, were not pronounced properly by the TTS system because the training corpus ...
