Google releases Gemini 3.8 Flash and Flash-Lite TTS

Google has released Gemini 3.8 Flash TTS and Gemini 3.8 Flash-Lite TTS, adding two text-to-speech models to its Gemini lineup. [1] Google calls the pair its “most expressive audio generation models yet.” [1] Both models support more than 100 languages. [1] The two products named in the release are Gemini 3.8 Flash TTS and the separately branded Gemini 3.8 Flash-Lite TTS. [1]

The paired launch matters less as a head-to-head comparison than as a choice Google is placing inside one TTS family; the strongest substantiated differentiators in the supplied report are Google’s expressiveness claim and multilingual scope, while it offers no basis for saying whether Flash or Flash-Lite is better for quality, speed, or cost. Practitioners should therefore treat the “most expressive” wording as vendor positioning until they can test the models against their own voices and languages. What the sources don't address: how Flash and Flash-Lite differ in availability, latency, pricing, controls, or measured audio quality.
