how to make agent wait for user to speal all 10 digit phone number before continue to talk considering they might um,uh for about 3seconds
t
Thanks for reaching out, Hai. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
I understand how important it is for the agent to patiently wait while the user speaks all 10 digits of their phone number, including those natural pauses like "um" or "uh." To help with this, you can adjust the
min_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:
Copy code
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.

what about when user say 571 umm uhh 505 uhmmm 1131?
t
I completely understand how tricky it can be when users include pauses and fillers like "umm" or "uhh" while saying a phone number (for example, "571 umm uhh 505 uhmmm 1131"). To help you navigate this smoothly, here are some friendly strategies you can try: 1. Enable Context-Aware Turn Detection: Consider using LiveKit's turn detection model, such as
MultilingualModel
. 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:
Copy code
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!

Could not find model livekit/turn-detector with revision v0.3.0-intl. Make sure you have downloaded the model before running the agent. Use
python3 your_agent.py download-files
to download the models.", "level": "ERROR", "name": "livekit.plugins.turn_detector", "pid": 7268, "inference": true, "timestamp": "2025-09-17T140002.987217+00:00"}
t
It looks like the error is telling us that the model
livekit/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!

can i use this instead
t
I completely understand how this might be a bit confusing, so let me help clarify things for you! The
StopResponse
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!

is this correct? session = AgentSession( _turn_detection_=MultilingualModel(), llm = openai.LLM(model="gpt-4.1-mini"), stt = deepgram.STT( model="nova-3", language="multi", ), tts = inworld.TTS( model="inworld-tts-1-max", temperature=1.0, pitch=0.0 ), # Stricter turn-taking: rely on VAD only (disable turn detector due to errors) vad=ctx.proc.userdata.get("vad"), _allow_interruptions_=False, _min_endpointing_delay_=3.5, _max_endpointing_delay_=6.0, )
t
Thank you for sharing your configuration with me! I see you’re using
MultilingualModel
for turn detection, GPT-4.1-mini for LLM, Deepgram STT, and Inworld TTS. I’d love to help you out—are you experiencing any specific issues with this setup, or are you looking for some guidance on whether it’s the right fit for your particular use case? Feel free to share more details, and we’ll work through it together!

it just cant pass this test case
4) “Thinking” after order prompt (no reprompt) • Agent: “What would you like to order?” • User: “Let me think…” then silence 5–7s. • Expect: Agent stays silent during this window (no “what would you like” reprompt). If still silent after ~8s, agent may gently suggest popular items.
t
To gently handle the test case where the user says "Let me think..." followed by 5–7 seconds of silence, and to ensure no reprompt during this quiet moment with a kind suggestion after about 8 seconds, here’s a friendly way to set up your LiveKit AgentSession: 1. Set `user_away_timeout`: This helps trigger a soft prompt after 8 seconds of silence:
Copy code
session = AgentSession(
    user_away_timeout=8.0,  # Changes user_state to 'away' after 8 seconds
    min_endpointing_delay=0.4,  # Allows short pauses within speech
    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":
Copy code
@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:
Copy code
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.

i only want to use turn dector plugin
t
Hi there! I wanted to share some important info about the LiveKit turn detector plugin. It can’t work on its own—it actually needs a speech-to-text (STT) plugin to convert speech into text, which it then uses to understand the flow of conversation. For example, it picks up on cues like when someone says, "Let me think..." and pauses. Here’s why the STT plugin is essential: • The turn detector looks at the transcribed text to figure out if the speaker plans to continue or has finished their turn. • It relies on STT output to catch phrases like "Let me think..." and decide how to handle silences appropriately. While the Silero VAD plugin is a helpful addition for handling interruptions smoothly, it’s optional. But the STT plugin is definitely a must-have for the turn detector to do its job. If you’re ready to set up the turn detector, here’s a simple way to configure it:
Copy code
from livekit.plugins.turn_detector.english import EnglishModel
from livekit.plugins import deepgram

session = AgentSession(
    turn_detection=EnglishModel(),
    stt=deepgram.STT(model="nova-3", language="en"),  # Required
    # vad=silero.VAD.load(),  # Optional but recommended
    # ... other components
)
