When to choose each
Eleven v4 Turbo
Best for
- Realtime voice agents
- Low-latency streaming speech
Watch out for
- ElevenLabs' latency figures exclude application and network latency
Gemini 3.8 Flash TTS
Best for
- Narration, audiobooks and product audio where voice quality matters more than cost
- Narration and voice output attached to an existing Gemini text pipeline
- Audio generation budgeted before the 2027 price step
Watch out for
- Google doubles the rates on 2027-01-01, to $1.00 input and $18 output per 1M tokens (about $0.027 per minute)
- Audio output is billed in audio tokens, which do not convert one-for-one to text tokens, so a text-token budget does not predict this cost
- Google's pricing page lists no context window or output cap for this model, so both are recorded as unknown
- No independent speech-quality benchmark is recorded here
