livekit-plugins-slng 1.5.9

Agent Framework plugin for STT and TTS services using SLNG's gateway.

SLNG plugin for LiveKit Agents

Support for SLNG's voice AI gateway in LiveKit Agents, providing access to multiple STT and TTS providers through a unified API.

See https://docs.slng.ai/ for more information.

Installation

pip install livekit-plugins-slng

Pre-requisites

You'll need an API key from SLNG. It can be set as an environment variable: SLNG_API_KEY

Region override

The plugin supports gateway region routing via the region_override option on both STT and TTS. This maps directly to the gateway's X-Region-Override header. See the available regions at docs.slng.ai/region-override.

You can pass either a single region:

stt = slng.STT(
    api_key="your-slng-api-key",
    model="deepgram/nova:3",
    region_override="eu-west-1",
)

Or multiple preferred regions in priority order:

tts = slng.TTS(
    api_key="your-slng-api-key",
    model="deepgram/aura:2",
    voice="aura-2-thalia-en",
    region_override=["eu-west-1", "us-east-1"],
)
