Rasa enables developers to build conversational AI agents using a modular pipeline that typically includes speech-to-text (STT) for voice input, natural language understanding (NLU) and dialogue management (often powered by LLMs), and text-to-speech (TTS) for voice output. The platform's flexible architecture allows seamless integration with third-party APIs, telephony systems, and custom business logic.
Developers typically build:
- Voice assistants for customer support
- Chatbots for websites and messaging apps
- Automated IVR (Interactive Voice Response) systems
- Virtual agents for healthcare and finance
- Multilingual conversational bots
- Custom workflow automation bots
