## Build Voice-Based Applications

Vocode provides tools and abstractions for you to build various voice-based applications on top of LLMs. You can set up LLMs to answer/make phone calls, act as personal assistants, or join Zoom meetings.

## Leverage Core Functionality

The library offers conversation abstractions like streaming and turn-based interactions, along with functionality such as endpointing and emotion tracking. It also integrates with leading speech-to-text and text-to-speech providers.

## Choose Your Deployment

You can use the Vocode hosted service to automate inbound/outbound calls via API, programming agents to execute tasks. Alternatively, leverage the open-source library for free to build your own custom solutions.
