# whisper-medium (Vokra GGUF)

Speech recognition model, converted to the Vokra GGUF format for [Vokra](https://github.com/ayutaz/vokra), a zero-dependency speech-AI inference runtime.

**This is a conversion, not a new model.** The weights are the upstream ones; Vokra re-packages them so its runtime can memory-map them directly. Credit for the model belongs upstream — see *Source* below.

## Usage

```bash
# Download (any HTTP client works — the file is a plain GGUF)
curl -L -o whisper-medium.gguf \
  https://huggingface.co/vokra/whisper-medium/resolve/main/whisper-medium.gguf
```

```bash
vokra-cli run --model whisper-medium.gguf --input speech.wav

# Beam search instead of greedy
vokra-cli run --model whisper-medium.gguf --input speech.wav --beam-size 5
```

Prints the transcript. Input must be mono 16 kHz WAV.

Every row above is read out of this file's own `vokra.*` metadata, so the card cannot claim something the artifact does not carry.

## Licence

The weights are distributed under **apache-2.0**, unchanged from upstream. Conversion does not alter the licence, and your obligations run to the upstream author.
