Google Unveils Gemini 3.8 Flash TTS, Enabling Natural Language Voice Customization and 30-Second Replication
Speech synthesis is reaching new heights of precision. On September 23, Google unveiled two advanced text-to-speech models—Gemini 3.8 Flash TTS and Gemini 3.8 Flash-Lite TTS—designed to meet the diverse demands of developers and creators for personalized voice acting and large-scale audio production.
Each model serves a distinct purpose. Gemini 3.8 Flash TTS specializes in voice and character design, allowing users to generate custom voices using natural language prompts. It enables precise control over tone, speed, and accents at the sentence level, along with efficient voice cloning from just a 30-second audio sample. Meanwhile, Gemini 3.8 Flash-Lite TTS is optimized for high-volume audio generation and cost-effective voice acting workflows.
Supporting over 100 languages and dialects, these models include 2,000 pre-built voices for immediate use. This robust multilingual capability empowers global developers and content creators to build sophisticated voice applications with ease.
