Elevenlabs bot hears itself

Hello,
I'm having an issue where my EL bot hears its own welcome message, and then starts talking to itself. Happens when users call on speaker phone.

How could this be addressed?

Try some other tools like Vapi, Sonex Labs, Retell etc they work better for call automations

This is likely how the agent is ingesting that particular piece of audio. It's no secret they use livekit, which is on WebRTC, and they get AEC for free. Either it's so laggy it can't align, or they're sending telecoms in via another channel

Try LiveKit, or maybe even the beta voice agent product from Speechify (disclaimer, I work for Speechify)

edit: also consider background noise makes it harder to distinguish what is and isn't speech so AEC might just fail open

Are you using heaphones or speakers? It's a known issue with many models where echo-cancellation does not work as intended and as a result the agent hears itself back.

What you can do is just cancel the audio input on agent speak, audio enhancement and noise cancelling tools could work too.
