## Overview

`FunASRTranscriber` uses [FunASR](https://github.com/modelscope/FunASR), an open-source speech recognition toolkit from Alibaba DAMO Academy, to transcribe audio files into Haystack `Document` objects. It runs entirely locally — no API key required.

The default model is `iic/SenseVoiceSmall`, a multilingual model supporting 50+ languages that is 5–10x faster than Whisper. Models are downloaded from ModelScope on first use and cached in `~/.cache/modelscope`.

The component accepts audio file paths (`str` or `Path`) as well as `ByteStream` objects. Call `warm_up()` before running in a pipeline to load the model into memory.

## Usage

### On its own

```python
from haystack_integrations.components.audio.funasr import FunASRTranscriber

transcriber = FunASRTranscriber()
transcriber.warm_up()

result = transcriber.run(sources=["speech.wav"])
print(result["documents"][0].content)
```

### In a pipeline

```python
from haystack import Pipeline
from haystack.components.fetchers import LinkContentFetcher
from haystack_integrations.components.audio.funasr import FunASRTranscriber

pipe = Pipeline()
pipe.add_component("fetcher", LinkContentFetcher())
pipe.add_component("transcriber", FunASRTranscriber())

pipe.connect("fetcher", "transcriber")

result = pipe.run(
    data={
        "fetcher": {
            "urls": ["https://example.com/interview.wav"],
        },
    }
)
print(result["transcriber"]["documents"][0].content)
```
