In Other News: A Bi-style Text-to-speech Modelfor Synthesizing Newscaster Voice with Limited Data
Tablica 6: Speech tempo: recordings vs test systems
['[BOLD] System', '[BOLD] Neutral', '[BOLD] Newscaster']
We define speech tempo of a corpus as the average number of phonemes present per second. Speech tempo is a crucial aspect in differentiating between the neutral and the newscaster styles. The newscaster-style is more dynamic than the neutral-style utterances, with higher speech tempo. We observe that the model conditioned on CWE can better model the speech tempo in both styles. This gives us additional evidence that conditioning the model on CWE helps us synthesise samples that are not only more style-appropriate, but are also better in naturalness with respect to natural recordings.
