- Spoken conversations: answering calls, intake, bookings

What it actually does
You configure a voice agent with your own knowledge, tools and rules, then deploy it on a phone line, in your app or on your website. It listens and speaks in natural-sounding voices across languages, and can take actions — look things up, book, route — during the call.
Where it is strongest
Anything that happens out loud. Inbound call answering, spoken intake, appointment booking and website voice assistants are where the realism of the voices and the speed of the conversation pay off.
Where it struggles
It is a voice specialist, not a general work agent. Getting an agent ready for real customers takes careful setup and testing, and usage-based pricing means high call volumes need cost monitoring.
How to get good results from it
Start with one narrow call type, script the opening and the fallback for anything the agent cannot handle, and listen to recordings before widening its scope. Set usage alerts on day one.
