# Speechmatics STT plugin for LiveKit Agents
Support for Speechmatics STT.
See [https://docs.livekit.io/agents/integrations/stt/speechmatics/](https://docs.livekit.io/agents/integrations/stt/speechmatics/) for more information.
## Installation
```bash
pip install livekit-plugins-speechmatics
```
Usage:
```python
from livekit.agents import AgentSession
from livekit.plugins.turn_detector.english import EnglishModel
from livekit.plugins import speechmatics
agent = AgentSession(
stt=speechmatics.STT(),
turn_detector=EnglishModel(),
min_endpointing_delay=0.5,
max_endpointing_delay=5.0,
...
)
```
Note: The plugin was built with
LiveKit's [end-of-turn detection feature](https://docs.livekit.io/agents/v1/build/turn-detection/) in mind,
and it doesn't implement phrase endpointing. `AddTranscript` and `AddPartialTranscript` events are emitted as soon
as they’re received from the Speechmatics STT engine.
## Pre-requisites
You'll need to specify a Speechmatics API Key. It can be set as environment variable `SPEECHMATICS_API_KEY` or
`.env.local` file.
