Vocode is an open-source developer platform for building real-time conversational voice AI applications. It provides tools for creating voice agents that can communicate with users through phone calls, web applications, and other interfaces.
Vocode combines speech-to-text, large language models, text-to-speech, and telephony services into a single framework, giving developers flexibility over the technologies used by their voice agents.
How Vocode Works
- Capture User Speech: Vocode receives speech from a phone call or supported voice application.
- Convert Speech to Text: The user's speech is processed through a speech-to-text service.
- Generate an AI Response: The transcribed input is sent to an LLM that determines the agent's response.
- Convert Response to Voice: The generated response is converted into spoken audio using a supported voice provider.
- Manage the Conversation: Vocode handles streaming, turn-taking, and interruptions during the conversation.
- Perform Actions: The voice agent can connect to external APIs and perform tasks such as scheduling appointments or updating systems.
