Before you decide
ElevenLabs Agents vs Gemini Live: buying questions
How should I compare ElevenLabs Agents and Gemini Live pricing?
ElevenLabs Agents: Monthly plans include call minutes and concurrency. LLM usage is billed separately; external telephony providers bill their own carrier charges. Enterprise terms are custom. Gemini Live: Standard Live API usage is token-metered: $3 per 1M input audio tokens ($0.005/min equivalent) and $12 per 1M output audio tokens ($0.018/min equivalent), plus separate text-token usage. Accumulated session context is billed each turn, so costs can grow with conversation history. Ask both vendors to quote the same expected workload, required channels, and implementation scope. Include required subscriptions and usage charges before comparing the total; the listed starting prices alone may cover different work.
Can ElevenLabs Agents and Gemini Live use my existing data?
The recorded knowledge and data sources for ElevenLabs Agents include Knowledge-base documents from files, URLs and text; Retrieval-augmented generation (RAG). For Gemini Live, they include Not publicly documented. Ask each provider to demonstrate access for the exact systems you use, with permissions, freshness, and failure behavior. A source missing from this directory is not proof that a provider cannot support it.
What should I test in a ElevenLabs Agents vs Gemini Live pilot?
Use the same representative calls, approved instructions, and escalation rules in both pilots. How does it handle interruption and uncertainty? Which actions can it complete, and which require approval? What context reaches a human during transfer? Record conversation quality, completed tasks, human handoffs, and total cost in the buyer worksheet. Check these specific cautions before launch: ElevenLabs Agents: Voice cloning requires authorization and governance. Budget for LLM usage, external carrier charges, overage and concurrency. Warm transfer messages require native Twilio; SIP REFER requires trunk support and has no warm message. Gemini Live: Google labels the Live API preview even though both Gemini 3.8 Live model IDs are stable. Native audio sessions use AUDIO response modality; enable output transcription for text. Audio-only sessions are limited to 15 minutes and audio-plus-video sessions to 2 minutes unless extended with session management. Client-to-server apps need ephemeral tokens. Accumulated audio/context is billed per turn.

Native audio agents: Gemini 3.8 Live (gemini-3.8-live) and Gemini 3.8 Live Extended Thinking (gemini-3.8-live-extended-thinking).; Separate TTS models: gemini-3.8-flash-tts and gemini-3.8-flash-lite-tts generate speech; neither is a Live agent.; Separate transcription endpoints: gemini-3.5-transcribe handles audio files; gemini-3.5-transcribe-live is a Live API speech-to-text mode, not a conversational agent.; Separate translation mode: gemini-3.5-live-translate-preview is a Live API interpreter for 70+ languages, not a conversational agent; it is preview.
Telephony
Native Twilio integration; SIP trunks for inbound and outbound calls
Not publicly documented
Call controls
Configurable turn-taking, interruptions and timeouts; Human transfer with channel-specific conference, blind and SIP REFER modes
Not publicly documented
Languages
Multilingual voice configuration; verify speech recognition, selected model and voice coverage for each required language.
The Live API documentation lists Japanese (ja) and multilingual support; native audio output can switch languages naturally in conversation. A supported-language list does not guarantee equivalent call quality. Separately, Transcribe lists Japanese (ja-JP) among 85+ languages; Flash TTS lists 130 languages and Flash-Lite TTS 101 (both include Japanese); Live Translate preview supports 70+ languages.
