vall-e: A Python repository from hyzhan

Language : 🇺🇸 | 🇨🇳

An unofficial PyTorch implementation of VALL-E(Neural Codec Language Models are Zero-Shot Text to Speech Synthesizers).

Inference: In-Context Learning via Prompting

model trained with nano config(about 100x smaller than the paper config) can synthesize human-like speech.

cd egs/libritts

# VALL-E
# nano config is too small, so the AR-Decoder may not work well.
# re-run to get new(diverse) result.

Broader impacts

Since VALL-E could synthesize speech that maintains speaker identity, it may carry potential risks in misuse of the model, such as spoofing voice identification or impersonating a specific speaker.

To avoid abuse, Well-trained models and services will not be provided.
