S3Tokenizer

S3Tokenizer is a Python library that provides a reverse-engineered PyTorch implementation of the Supervised Semantic Speech Tokenizer (S3Tokenizer), originally proposed in CosyVoice. It enables high-throughput batch inference and online speech code extraction. The current version is 0.3.0, and the library demonstrates a rapid release cadence, frequently adding support for newer CosyVoice versions and improving audio processing capabilities.
