Vocode

Automating phone calls with a realistic AI voice is what Vocode does, for both inbound and outbound calls.

Vocode is an AI call center and voice agent tool that handles conversations over the phone, so you can have it answer callers or place calls on your behalf instead of staffing a line.

It sits in the AI API space too, which suggests it is made for developers who want to build voice agents into their own products rather than people looking for a ready-made dashboard.

Its category tags cover speech recognition and speech synthesis, the two pieces a phone agent needs to listen and talk back.

Pricing is listed as free.

Treat that as the starting point and check the website for current limits before you plan a deployment.

If you are building something that needs to talk to customers by phone, Vocode is a practical place to start, particularly if you are comfortable working with code.
