09/12/2025, 3:40 PMI'm happy to help you understand how LiveKit handles events when a user stops speaking and another user, like an agent, starts speaking. Depending on the version of the LiveKit Agents framework you're using, the events vary a bit:
• For LiveKit Agents v0.x: You’ll want to look out for the events

09/12/2025, 3:40 PMI'd love to share some example code snippets to help you handle speaking state events in LiveKit. Let's walk through them together:
For LiveKit Agents v0.x:
Copy code
@agent.on("user_started_speaking")
def user_started_speaking():
print("User started speaking")
@agent.on("user_stopped_speaking")
def user_stopped_speaking():
print("User stopped speaking")
@agent.on("agent_started_speaking")
def agent_started_speaking():
print("Agent started speaking")
@agent.on("agent_stopped_speaking")
def agent_stopped_speaking():
print("Agent stopped speaking") Copy code
@session.on("user_state_changed")
def on_user_state_changed(ev):
if ev.new_state == "speaking":
print("User started speaking")
elif ev.new_state == "listening":
print("User stopped speaking")
@session.on("agent_state_changed")
def on_agent_state_changed(ev):
if ev.new_state == "speaking":
print("Agent started speaking")
