FAQ
Can an AI voice agent answer my business calls like a receptionist?
Yes. I connect it to your number through Twilio or SIP. It answers, handles common questions, books appointments, takes messages, and transfers to a human when needed.
LiveKit or Vapi, and others which one should I use?
Vapi is quicker to launch and fine for standard call flows. LiveKit gives more control over latency, custom logic and cost at scale. I’ll recommend one after you tell me your use case.
. How fast will the AI voice agent respond?
It depends on the models and setup you pick. I tune for natural back-and-forth and clean interruption handling. Tell me your target and I’ll say what’s realistic before we start
Does Voice agent support multi languages Ai?
Yes. Tell me which languages and I’ll choose speech and voice models that suit them. I’ll test with real calls before delivery.
I already have a voice agent but it lags, echoes or cuts people off. Can you fix it?
Yes, that’s the Basic package. I find the cause of the lag, echo, interruptions or broken tool calls and fix it. It also works for Retell AI, Synthflow and Assistable agents.
