mms_fa.onnx | 3.2 MB | ONNX model graph |

tokenizer_path = hf_hub_download("xycld/lyric-align-mms-fa", "tokenizer.json")
Note: mms_fa.onnx.data must be in the same directory as mms_fa.onnx for ONNX Runtime to load correctly. hf_hub_download handles this automatically via its cache.
| Variant | Size | Compression | Load Time | Inference | MAE | Acc @50ms | Acc @100ms | Acc @200ms | Status |
|---|---|---|---|---|---|---|---|---|---|
| FP32 (original) | 1,207 MB | 1.0x | 989ms | 424ms/line | 34.7ms | 86.2% | 97.5% | 99.4% | Available |
| FP16 | 605 MB | 2.0x | 2,335ms | 576ms/line | 34.7ms | 86.2% | 97.5% | 99.4% | Not recommended |
| UINT8 | 303 MB | 4.0x | 412ms | 262ms/line |
Benchmark: Chinese song "错位时空" (362 characters, 53 lines) on CPU.
UINT8 is the recommended variant — 75% smaller, 38% faster inference, with virtually no accuracy loss (MAE +0.2ms).
FP16 is not recommended for CPU inference (no native FP16 support, slower than FP32). INT8 (QInt8) is incompatible with some ONNX runtimes due to ConvInteger operator requirements.
This is an ONNX format conversion of Meta's MMS forced alignment model, originally distributed via torchaudio.pipelines.MMS_FA.
