Vocode

Vocode – Open Source Voice AI Platform is an open-source framework and ecosystem for building, deploying, and scaling hyperrealistic voice agents. It provides the core building blocks, orchestration, and APIs to manage AI-driven voice experiences on phone calls and other audio channels, built to work on top of any AI stack.

---

How it works

• Core: Vocode Core offers the integrations, abstractions, and orchestration needed to compose voice applications from AI components.
• API: Vocode API provides an enterprise-grade interface to manage AI agents on phone calls, built on top of Vocode Core.
• SDKs: Client libraries (Python, Node) to integrate and deploy voice agents into applications and services.
• Modularity: Separate repositories (e.g., vocode-core, vocode-api-python, vocode-api-node, vocode-api-generator) enable modular development and custom SDK generation.
• Voice-first: Designed to enable voice-based LLM agents and rich conversational capabilities over telephony and VOIP channels.

Getting started

• Explore the core repositories:
• vocode-core: Build voice-based LLM agents with modular, open-source components.
• vocode-api-python: Python SDK for interacting with the Vocode API.
• vocode-api-node: Node.js SDK for the Vocode API.
• vocode-api-generator: Generates SDKs from Vocode’s Fern API.
• Use the SDKs to create, deploy, and manage AI voice agents in applications that require telephony or audio-based interactions.
• Contribution and community: As an open-source project, it encourages collaboration, sharing improvements, and extending capabilities.

Key Repositories

• vocode-core: Build voice-based LLM agents; modular and open source.
• vocode-api-python: Python SDK for the Vocode API.
• vocode-api-node: Node.js SDK for the Vocode API.
• vocode-api-generator: Fern API-based generator to create additional SDKs.
• Additional tooling and demos (e.g., vocode-next-template, vocode-react-sdk) to accelerate experimentation and UI integrations.

---

Safety and Considerations

• As with any voice AI system, ensure compliance with local regulations, consent from participants, and privacy requirements when recording or processing calls.

---

Core Concepts

• Voice agents: AI-driven entities that can converse, respond, and perform actions over voice calls.
• Orchestration: Managing multiple components and AI services to deliver a coherent voice experience.
• API-driven: Centralized APIs to control agent lifecycle, call routing, and analytics.
• SDKs: Pre-built clients to simplify integration and accelerate development.

---

Target Use Cases

• Customer support hotlines with intelligent routing and self-service options
• IVR systems enhanced with LLM-powered dialogue
• Telemarketing or sales assistants with natural language capabilities
• Any voice-enabled automation requiring scalable, AI-driven conversations

---

Safety and Legal Considerations

• Obtain proper consent for recording and processing calls where required by law.
• Ensure transparent disclosure of AI involvement in conversations where appropriate.
