Minimal Citrinet inference example in Rust using ONNX Runtime (`ort`) and `kaldi-native-fbank` for feature extraction.
```bash
cargo run --release -- \
--model model.onnx \
--tokens tokens.txt \
--audio test_wavs/0.wav
```
Inputs are expected to be mono 16 kHz WAV audio and a token file formatted as `symbol index` per line (batch size 1). Defaults match the sample paths above.
