Thanks — I’m responding to your question about how to set Norwegian (or a preferred accent) in the system instructions for the new Grok Realtime API. You set the preferred language and speaking style by including it in the agent’s system

instructions

. Example (Python):

from livekit.agents import AgentSession
from livekit.plugins import xai

session = AgentSession(
    llm=xai.realtime.RealtimeModel(
        voice="Ara",
        instructions="You are a helpful assistant. Respond in Norwegian (Bokmål). Use natural pronunciation, appropriate intonation, and culturally-aware speech rhythms. Keep a friendly, conversational tone."
    ),
)

Notes: • Specify the language and any preferred variant (e.g., “Bokmål”) in plain text inside

instructions

. • Specific Norwegian dialect codes (like

nb-NO

) aren’t selectable here; use descriptive instructions instead. • If users will speak Norwegian, ensure your STT component supports Norwegian for accurate transcription. Would you like a short JS/TS example or a version that requests a particular accent (e.g., “Oslo accent”) in the instructions? Sources: xAI Grok Voice Agent API plugin | LiveKit docs

Thanks — I’m responding to the error you shared about

RealtimeModel.__init__()

rejecting the

instructions

argument and your goal to set Norwegian. What I’m seeing: your runtime error means the installed xAI plugin version doesn’t accept

instructions

on

xai.realtime.RealtimeModel

, even though the API supports language-setting via system instructions. To move forward I can help two ways — please pick one or provide the requested info: 1) Quick check & fix (recommended) • Run and share the output of:

pip show livekit-agents livekit-plugins-xai

I’ll confirm if your versions lack the

instructions

parameter and give the exact upgrade command to install the release that includes it. 2) Immediate workaround (no SDK change) • Remove

instructions

from the

RealtimeModel

constructor and inject your language guidance at session start instead. Example pattern:

session = AgentSession(llm=xai.realtime.RealtimeModel(voice="Ara"))
  await session.say("Fra nå av svarer jeg på norsk (Bokmål).")

• Or include a first-system message in your agent flow that instructs the model to respond in Norwegian and with the desired intonation. If you want, share the

pip show

output and the snippet where you construct

RealtimeModel

and I’ll give the exact upgrade or code change to apply. Sources: OpenAI Realtime API plugin guide | LiveKit docs | xAI and LiveKit | LiveKit docs | Gemini Live API plugin | LiveKit docs
