# campplus-speaker-encoder (Vokra GGUF)

Speaker embedding 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 campplus.gguf \
  https://huggingface.co/vokra/campplus-speaker-encoder/resolve/main/campplus.gguf
```

```bash
# 192-d speaker embedding
vokra-cli run --model campplus.gguf --input a.wav

# Cosine similarity between two utterances
vokra-cli run --model campplus.gguf --input a.wav --compare b.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.
