How the top Google Gemini Live API alternatives compare

A closer look at the top 4: each Google Gemini Live API alternative's standing among Voice AI peers, its verdict record against Google Gemini Live API, and the trade-offs of leaving.

1. OpenAI Realtime API

Our use-case verdicts have OpenAI Realtime API ahead of Google Gemini Live API for custom pipeline control, ecommerce support and orders and outbound sales campaigns and matches it for no-code agency deploys, healthcare compliance and smb receptionist and booking.

Seen from the other side, Google Gemini Live API vs OpenAI Realtime API: no native sip trunking.

Why teams switch: Both tools are API-first and neither supports bring-your-own LLM, so those critical pipeline-control factors cancel out. The tiebreaker for engineering teams building custom pipelines is native SIP trunking: OpenAI Realtime API supports it natively, while Google Gemini Live API does not. SIP connectivity is essential for teams wiring real telephony into a custom pipeline without adding a separate third-party layer. OpenAI also exposes WebRTC, WebSocket, and SIP transport plus MCP and tool calling, giving engineering teams more low-level control over the call path. Custom pipeline control verdict →

Overall verdict: OpenAI Realtime API claims three outright wins across custom pipeline control, ecommerce support, and outbound sales campaigns, while Google Gemini Live API wins none. A decisive structural advantage is native SIP trunking support, which Google Gemini Live API lacks entirely. SIP trunking lets teams connect existing telephony infrastructure directly, making outbound sales campaigns and ecommerce support deployments far simpler to build and operate. On custom pipeline control, OpenAI Realtime API's native WebRTC, WebSocket, and SIP integration paths alongside MCP and tool calling give developers precise control over call flow that LiveKit or Pipecat middleware layers cannot fully replicate. Google Gemini Live API's $0.018/min base rate and 70-language support are genuine strengths, but they did not translate into a single outright win.
