# Speech-to-text quick start

```python
from matrx_ai.processing.audio import STTRequest, execute_stt

result = await execute_stt(
    STTRequest(audio_source=audio_bytes, model="stt-default")
)
print(result.text)
```

`stt-default` is a catalog alias, not a provider/model constant. A standalone host supplies a
model-catalog entry with `wire_format="groq_stt"` (or another registered `*_stt` adapter).
