# CAM++

**Speaker Verification & Diarization** — identify and distinguish speakers in audio.

CAM++ is a speaker embedding model used for speaker verification (is this the same person?) and speaker diarization (who spoke when?).

## Quick Start

```python
from funasr import AutoModel

# Speaker diarization as part of ASR pipeline
model = AutoModel(
    model="funasr/paraformer-zh",
    hub="hf",
    vad_model="funasr/fsmn-vad",
    punc_model="funasr/ct-punc",
    spk_model="funasr/campplus",
    device="cuda",
)
result = model.generate(input="meeting.wav")
# Each sentence has a speaker label
for sentence in result[0]["sentence_info"]:
    print(f"[Speaker {sentence['spk']}] {sentence['text']}")
```

## Features

- Speaker embedding extraction
- Speaker verification (same/different speaker)
- Speaker diarization (multi-speaker segmentation)
- Works with FunASR pipeline via `spk_model` parameter
