Qwen3-TTS-Tokenizer-12Hz is the separate **speech tokenizer / codec** used by the Qwen3-TTS family: - 10 supported languages: `zh en ja ko de fr ru pt es it` - 12.5 Hz, 16-codebook speech representation - used for reference-audio encoding, voice-pack baking, and final waveform decode - Apache-2.0 licence This repo contains the **tokenizer / codec** only. Use it together with the talker GGUF from [`cstr/qwen3-tts-0.6b-base-GGUF`](https://huggingface.co/cstr/qwen3-tts-0.6b-base-GGUF). ## Files File | Size | Notes --- | --- | --- `qwen3-tts-tokenizer-12hz.gguf` | 342 MB | F16 `qwen3-tts-tokenizer-12hz-q8_0.gguf` | 277 MB | Q8_0 codec quant ## Quick Start ```bash ./build/bin/crispasr \ --backend qwen3-tts \ -m qwen3-tts-12hz-0.6b-base.gguf \ --codec-model qwen3-tts-tokenizer-12hz.gguf \ --voice clone.wav \ --ref-text "Exact transcript of clone.wav" \ --tts "Hello there" \ --tts-output hello.wav ``` The tokenizer GGUF is used for: - encoding reference audio into `ref_code` - baking / loading voice-pack GGUFs - decoding generated codes back into 24 kHz mono WAV ## Quantisation Notes Current CrispASR validation status: - `qwen3-tts-tokenizer-12hz.gguf` - reference baseline - `qwen3-tts-tokenizer-12hz-q8_0.gguf` - usable, but numerically less faithful than the F16 codec in strict diff tests For best fidelity, keep the tokenizer / codec at F16 even when quantising the talker. In current CrispASR testing, codec quantisation drifts earlier in the codec-encoder path than talker-only quantisation. This repo may also publish lower-bit talker variants in the companion talker repo. If you use them, the safest pairing is still: - quantised talker - `qwen3-tts-tokenizer-12hz.gguf` kept at F16 In other words: if you must choose where to keep precision, keep it in the tokenizer / codec first. ## How this...
