Overview
- Gemini 3.8 Flash TTS and Flash‑Lite TTS began rolling out to developers this week through the Gemini API and Google AI Studio and are appearing in Gemini Notebook and Google Vids for broader use.
- Flash TTS is focused on creative, line‑by‑line directing and long‑form fidelity while Flash‑Lite targets high‑volume, lower‑cost dubbing and voice-agent workloads, and both support over 100 languages and two‑speaker scene staging.
- Google’s developer docs introduce a Voices endpoint that creates reusable voice IDs from a 10–30 second reference clip plus a separate verbal consent recording; Google verifies the match and returns managed voice identifiers for reuse or short‑lived encrypted keys.
- Google made Gemini 3.8 Live with Live Avatar generally available to Gemini Enterprise this week, offering low‑latency animated personas with precise lip‑sync across 97 languages, asynchronous backend tool calls, and custom avatar creation by enterprise allowlist.
- The company embeds SynthID watermarks and C2PA provenance in generated audio/video and cites top placements on third‑party benchmarks, but enterprise API access, some regional availability, cost and latency tradeoffs remain staged and should be tested by buyers.
