Gemini 3.8 TTS Playground
Read the original on Simon Willison →Google has launched two new Gemini text‑to‑speech models—gemini‑3.8‑flash‑tts and gemini‑3.8‑flash‑lite‑tts—offering a library of over 2,000 voices and the option to create a custom voice from a 30‑second audio sample. The author built a playground interface that lets users define multi‑character conversations with distinct voices and styles, and demonstrated it with a scripted dialogue between two pelicans. Generating 1 minute 18 seconds of audio with the Flash model took about 20 seconds and cost 2.74 cents.
