About VALL-E X
VALL-E X is a cross-lingual neural codec language model designed for speech synthesis, capable of generating natural speech in a target speaker's voice from just a short audio sample, even in languages unseen during training. It extends the original VALL-E architecture by enabling zero-shot cross-lingual text-to-speech, meaning it can synthesize speech in a different language than the one used in the reference audio. The model is open-source and available for research and development.
Key Features
Cross-lingual zero-shot text-to-speech

FAQ
What is VALL-E X?
VALL-E X is a neural codec language model for cross-lingual speech synthesis. It can generate speech in a target speaker's voice from a short audio sample, even if the audio sample is in a different language than the desired output.
Is VALL-E X open-source?
Yes, VALL-E X is open-source and available for research purposes. The code and pre-trained models are typically hosted on GitHub.
