3D-Speaker: A Large-Scale Multi-Device, Multi-Distance, and Multi-Dialect Corpus for Speech Representation Disentanglement
Disentangling uncorrelated information in speech utterances is a crucial
research topic within speech community. Different speech-related tasks focus on
extracting distinct speech representations while minimizing the affects of
other uncorrelated information. We present a large-scale speech corpus to
facilitate the research of speech representation disentanglement. 3D-Speaker
contains over 10,000 speakers, each of whom are simultaneously recorded by
multiple Devices, locating at different Distances, and some speakers are
speaking multiple Dialects. The controlled combinations of multi-dimensional
audio data yield a matrix of a diverse blend of speech representation
entanglement, thereby motivating intriguing methods to untangle them. The
multi-domain nature of 3D-Speaker also makes it a suitable resource to evaluate
large universal speech models and experiment methods of out-of-domain learning
and self-supervised learning. https://3dspeaker.github.io
An investigation of speaker independent phrase break models in End-to-End TTS systems
This paper presents our work on phrase break prediction in the context of
end-to-end TTS systems, motivated by the following questions: (i) Is there any
utility in incorporating an explicit phrasing model in an end-to-end TTS
system?, and (ii) How do you evaluate the effectiveness of a phrasing model in
an end-to-end TTS system? In particular, the utility and effectiveness of
phrase break prediction models are evaluated in in the context of childrens
story synthesis, using listener comprehension. We show by means of perceptual
listening evaluations that there is a clear preference for stories synthesized
after predicting the location of phrase breaks using a trained phrasing model,
over stories directly synthesized without predicting the location of phrase
breaks.Comment: Submitted for review to IEEE Acces
