Gemini Live API enables real-time voice and vision interactions through streaming conversational models.
Gemini Live API processes continuous audio, images, and text streams to generate spoken responses. Its voice-agent features include interruptions, multilingual conversation, function calling, input and output transcripts, proactive audio, and response styles that adapt to user expression.
Applications connect through stateful WebSocket sessions, either from a backend or directly from a frontend. Google provides SDK and WebSocket tutorials, agent development tools, and partner integrations for building conversational interfaces across customer support, education, gaming, and other applications.
