Audio Samples

!!! Wearing headphones is strongly recommended to judge the audio quality !!!

Speech Tokenization & Resynthesis

Samples are randomly selected from LibriSpeech test-clean subset.

Ground Truth 256k bps
SpeechTokenizer 500 bps
HuBERT + Unit-HiFiGAN 500 bps
UniWav 500 bps
SpeechTokenizer 1k bps
UniWav 1k bps

In-context Text-to-Speech

Samples are randomly selected from LibriSpeech test-clean subset. First 3 seconds of the ground truth are used as audio prompt.
