# native-whisperx

Reusable workflow library for composing `moritzbrantner-*` transcription,
alignment, diarization, and transcript crates into a WhisperX-style pipeline.

This crate owns workflow configuration and output writing. The reusable audio,
text, model-runtime, and speaker primitives remain in `rust-packages`.

## Release Role

`native-whisperx` is the library crate for Workflow Composition APIs. It is
published before `native-whisperx-cli`. After that manual release order, Cargo
users install the CLI package with:

```bash
cargo install native-whisperx-cli
```

The installed terminal command is `native-whisperx`.

## Workflow Surface

The crate composes native transcription, default wav2vec2 alignment, optional
speaker diarization, optional segment-level post-ASR translation, and output
writing. The user-facing parity target is the Python WhisperX CLI. Delegated
features remain delegated where the repository has not yet replaced them with a
Rust-Native Parity path.

Default `json` output is WhisperX JSON. Use `native-json` through the CLI when
you need the Rust transcript contract shape.

Installing the CLI package does not make transcription resources available.
Model bundles, cache entries, CUDA, Python WhisperX compatibility resources,
and gated Hugging Face assets are resolved by the invoked workflow. Delegated
Feature paths remain delegated until separate Rust-Native Parity work replaces
them.

## Feature Flags

| Feature | Purpose |
| --- | --- |
| `native` | Native Candle Whisper and wav2vec2 alignment composition. Enabled by default. |
| `translation` | Helsinki-NLP OPUS-MT/Marian post-ASR segment translation. Enabled by `native`. |
| `cuda` | CUDA-backed Candle execution for hosts with a local CUDA toolchain. |
| `media-decode` | Non-WAV media/container decode through the audio I/O crate. |
| `diarization` | Heuristic speaker diarization composition. |
| `onnx-diarization` | Explicit ONNX speaker embedding diarization path. |
| `pyannote-diarization` | Explicit native pyannote community diarization bundle path. |
| `silero-vad` | Explicit Silero ONNX VAD path. |
| `pyannote-vad` | Explicit local pyannote ONNX VAD path. |
| `whisperx-compat` | External Python WhisperX command compatibility and parity checks. |
