09/17/2025, 1:42 PMmin_endpointing_delay parameter in the agent's settings. This setting controls the minimum silence duration before the agent recognizes that the user has finished speaking.
Here’s a friendly guide to setting it up:
• Use silero.VAD.load() as your Voice Activity Detection (VAD) engine.
• Set min_endpointing_delay to 3.0 seconds so the agent allows for those natural pauses without cutting off early.
Here’s an example configuration for you:
agent = VoicePipelineAgent(
vad=silero.VAD.load(),
stt=deepgram.STT(),
llm=openai.LLM(),
tts=cartesia.TTS(),
min_endpointing_delay=3.0 # Wait up to 3 seconds of silence before ending turn
)
This approach helps make sure the agent listens long enough to catch every digit, even with pauses, while avoiding interruptions. If you have any questions or need a hand with this, please don’t hesitate to reach out—I’m here to help!

09/17/2025, 1:47 PMMultilingualModel. It smartly adjusts silence thresholds to accommodate those natural fillers and pauses, making sure the agent patiently waits for the user to finish speaking.
2. Configure STT for Numeral Formatting: Using an STT provider like Speechmatics in "flexible" mode can be a real game-changer. This mode helps transcribe numbers accurately, even when there are interruptions, by delaying the final transcription until the full number is captured.
3. Clean Up Fillers Programmatically: You might find it helpful to implement a hook like on_user_turn_completed() to process the transcription, gently remove fillers, and extract the phone number. Here's a simple example:
class PhoneNumberAgent(Agent):
async def on_user_turn_completed(self):
raw_text = self.chat_ctx.messages[-1].text
cleaned = self._extract_phone_number(raw_text)
if cleaned:
await self.session.generate_reply(f"Got it, your number is {cleaned}.")
By following these steps, your agent can gracefully handle natural speech patterns while accurately capturing phone numbers. If you'd like, I’m here to walk you through any of these configurations in more detail—just let me know!

09/17/2025, 2:01 PMlivekit/turn-detector with revision v0.3.0-intl hasn’t been downloaded yet. No worries—we can fix this together! Here’s what you can do to get everything up and running:
1. Open your terminal and run this command to download the necessary model files:
`python3 your_agent.py download-files`Just make sure to replace your_agent.py with the actual path to your agent script.
2. If you’re working with Node.js, try:
`pnpm download-files`or
node ./your_agent.ts download-files
3. Once the download finishes, please restart your agent so it can load the model properly.
If you’re still running into issues, here are a few things to double-check:
• Your environment needs internet access to download the files.
• The cache directory (usually ~/.cache/huggingface/hub) should have the right permissions to allow writing.
• If you think the download might have gotten corrupted, you can delete the cache folder at ~/.cache/huggingface/hub/models--livekit--turn-detector and then try downloading again.
Please don’t hesitate to reach out if you need any more help or run into other problems—I’m here to support you!

09/17/2025, 2:35 PMStopResponse method and the turn-detector model actually have different roles:
• `StopResponse`: Think of this as a way to gently stop the agent's reply during a conversation, especially if a user's message is invalid or empty. However, it doesn’t handle turn detection or figure out when someone has finished speaking.
• Turn-Detector Model: This one is designed specifically to help detect when a turn ends by looking at the flow of the conversation. It helps reduce interruptions during natural pauses, but it does require downloading the model weights to work correctly.
So, to get accurate turn detection, it’s important to download and initialize the turn-detector model. If you’d like, I’m here to guide you through the setup or answer any questions you might have!

3. Testing turn detection predictions (Node.js):
const eouModel = new turnDetector.MultilingualModel();
const result = await eouModel.predictEndOfTurn(chatCtx);

max_endpointing_delay=6.0, # Max silence before forced endpoint
stt=deepgram.STT(),
tts=openai.TTS(),
vad=silero.VAD.load(),
llm=openai.LLM()
)
2. Handle the user_state_changed event: Use this to kindly follow up when the user becomes "away":
@session.on("user_state_changed")
def on_user_state_changed(state):
if state == "away":
session.say("Still thinking? Let me know when you're ready.", allow_interruptions=True)
3. Optionally respond to "Let me think...": Catch this phrase and offer immediate encouragement:
async def on_user_turn_completed(chat_ctx, message):
if "let me think" in message.text.lower():
await session.say("Take your time!", add_to_chat_ctx=False)
This setup helps your agent stay quiet during that thoughtful 5–7 second pause and then gently check in after about 8 seconds. If you have any questions or want to tweak this further, I’m here to help!
