How long does it take
to set up?

It takes about six weeks to build, integrate, and deploy a customer-led voice assistant. Don’t worry; if you can’t provide training data, we can get everything we need by speaking with your people.

How does this fit in with my contact center tech stack?

Calls are routed to the voice assistant through a SIP or PTSN integration into your CCaaS platform or telephony provider. Other systems can be integrated via APIs.

What languages do
you offer?

We offer 45 languages as standard, and counting. We are currently live in English, French, German, Spanish, Polish, Portuguese, Swedish, and more.

Can you automate complex conversations?

Yes. Using a combination of generative and retrieval AI models with our patented dialogue policy technology means our voice assistants can handle complex calls like troubleshooting, 

Do you offer chat?

Yes. We take a voice-first approach to conversation design to ensure the best, customer-led experiences, but we can offer customer-led assistants on any channel.

Can you hand calls over to our people?
