xiaoyuzhou-asr

⚙️ Configuration

1. xyz API server running — fetches episode data and audio URLs from 小宇宙

   git clone https://github.com/ultrazg/xyz.git && cd xyz && go run .
   # Default port: 23020, change with -p
   

2. Access token — login via POST /sendCode then POST /login (see references/xyz-api.md) 3. ffmpeg — audio format conversion (brew install ffmpeg) 4. Qwen3-ASR model — download (HF Hub does NOT ship tokenizer.json):

   python3 -c "
   from huggingface_hub import snapshot_download
   snapshot_download('Qwen/Qwen3-ASR-0.6B', local_dir='models/0.6B')
   "
   

5. qwen3-asr-rs — build from source:

   git clone https://github.com/alan890104/qwen3-asr-rs.git && cd qwen3-asr-rs
   cargo build --release --example local_transcribe
   

6. tokenizer.json — auto-generated by the transcription script on first run (from vocab.json + merges.txt). No manual step needed.

🔒 Constraints

MUST split audio into ≤3-minute segments for Metal GPU stability

Audio must be WAV 16kHz mono

tokenizer.json must be generated manually (not included in HF download)

local_transcribe binary needed (demo binary only runs built-in test samples)

xyz API requires Chinese phone number (+86) login

All processing is local — audio never leaves the machine
