RTZR plugin for LiveKit Agents
Support for RTZR Streaming STT via WebSocket interface, following the "Streaming STT" guide in the RTZR Developers docs.
- Docs:
https://developers.rtzr.ai/docs/en/(see Streaming STT)
Installation
pip install livekit-plugins-rtzr
Prerequisites
Obtain client_id and client_secret from the RTZR Developers Console.
Set credentials as environment variables:
RTZR_CLIENT_ID=<your_client_id>
RTZR_CLIENT_SECRET=<your_client_secret>
# Override base HTTP API URL (used for token issuance)
RTZR_API_BASE=https://openapi.vito.ai
# Override WebSocket URL (used for live streaming)
RTZR_WEBSOCKET_URL=wss://openapi.vito.ai
If RTZR_WEBSOCKET_URL is not set, the plugin will derive it from RTZR_API_BASE by replacing the scheme with wss://.
Usage
Use RTZR STT in an AgentSession or as a standalone streaming service.
from livekit.agents import AgentSession
from livekit.plugins import rtzr
# Basic usage with env-based credentials
stt = rtzr.STT()
session = AgentSession(
stt=stt,
# ... llm, tts, etc.
)
Keyword boosting (Streaming STT only, sommers_ko model only):
stt = rtzr.STT(
model="sommers_ko",
keywords=[
"키워드",
("부스팅", 3.5),
"키위드:-1.0",
],
)
Rules:
- Use list entries as
keywordorkeyword:score, or use(keyword, score)tuples. - Score must be between -5.0 and 5.0, up to 100 keywords, each <= 20 chars.
- Keywords must be written in Korean pronunciation (Hangul and spaces only); non-Korean input will error.
Notes:
- The WebSocket streaming endpoint accepts raw PCM frames when
encoding=LINEAR16. - The plugin relies on the server-side endpointing (EPD). You do not need to send finalize messages.
- When the pipeline closes the stream, the plugin sends
EOSto end the session.
