# Deepgram STT

[Deepgram](https://deepgram.com) provides fast, accurate real-time speech-to-text with built-in turn detection. Ideal for conversational agents.

<Info>
  Vision Agents requires a [Stream](https://getstream.io/try-for-free/) account
  for real-time transport. Most providers offer free tiers to get started.
</Info>

<Tip>
  Deepgram also provides low-latency [text-to-speech](/integrations/tts/deepgram). You can use both in the same agent.
</Tip>

## Installation

```sh theme={null}
uv add "vision-agents[deepgram]"
```

## Quick Start

```python theme={null}
from vision_agents.core import Agent, User
from vision_agents.plugins import deepgram, gemini, getstream

agent = Agent(
    edge=getstream.Edge(),
    agent_user=User(name="Assistant", id="agent"),
    instructions="You are a helpful assistant.",
    llm=gemini.LLM("gemini-3-flash-preview"),
    stt=deepgram.STT(),
    tts=deepgram.TTS(),
)
```

<Warning>
