While Gemini 3.8 & 3.8 Live Extended Thinking are powerful for real-time dialogue, the best alternative depends on your priorities. OpenAI Realtime API is a direct competitor with strong ecosystem support; Amazon Nova Sonic and Microsoft Azure AI Speech cater to enterprise cloud users; ElevenLabs leads in voice quality; Rasa offers open-source flexibility; Deepgram focuses on performance; and Anthropic Claude provides thoughtful, safety-oriented conversations. Evaluate based on latency, integration, customization, and cost to find the ideal fit.
