Google DeepMind's Gemini 3.8 Flash TTS and Gemini 3.8 Flash-Lite TTS take #1# on all seven Voice Arena TTS language boards. @voicearena_ai evaluated both models ahead of today's launch, and the results were phenomenal. Every ranking on Voice Arena comes from blind, head-to-head votes by vetted native speakers, scored with Bradley-Terry Elo. On US English, Flash-Lite takes #1# of 20 at 1087 Elo, 19 points above Cartesia's Sonic-3.6 and inside the statistical band at the top, with Gemini 3.8 Flash at #3# on 1061. Outside US English the two models finish #1# and #2# on five of the six remaining boards, with Gemini 3.1 Flash TTS behind them in third, so Google DeepMind holds the entire top three in Japanese, Arabic, Mexican Spanish, Vietnamese and Brazilian Portuguese. Results backed by thousands of blind, head-to-head listener votes from native speakers across seven languages. Congratulations to @GoogleDeepMind on the release!
