Improving Prosody Modelling with Cross-Utterance Bert Embeddings for End-to-End Speech Synthesis

ICASSP 2021accepted

Although speech prosody is related to the linguistic information up to the discourse structure, most text-to-speech (TTS) systems only take into account the information within each sentence. This makes it challenging when converting a paragraph of text into natural and expressive speech. In this pap…
