Ask HN: How do you defend support AI agents from voice prompt injection?

[theHolyTrynity]

We are securing a customer support agent that does the following: - retrieve data around company services from a RAG - is connected to a few tools to escalate to humans and write support tickets - has voice (11labs)

we did complete assessment for normal prompt injection with our tools

but is there any solution for voice attacks?

yes indeed, but it is not enough and was looking to find more stuff to try specifically for voice
