About Gemini 3.8 Flash-Lite TTS is Google’s cost-efficient text-to-speech model designed for high-volume dubbing, audio production, and expressive voice-agent applications. The model provides fine-grained control over tone, pacing, expressive nuance, and line-by-line vocal delivery. It supports long-form speech generation while maintaining natural pacing, voice quality, and speaker consistency across extended content. Native two-speaker scene staging enables multi-turn dialogue with distinct voices and natural conversational turn-taking from a single script. Gemini 3.8 Flash-Lite TTS supports more than 100 languages and can add nonverbal cues and backchanneling to create more natural conversational audio. The model is available through the Gemini API and Google AI Studio, with deployment through Google Vids and planned enterprise availability through Gemini Enterprise.	About Use the browser with in-app prompts and a recording tool. A predefined set of phonetically balanced sentences is available to create a 30-minute dataset for training a TTS model to learn your unique voice. Make the model sound like you by choosing the range that best suits the pitch of your voice. The recommended typical voice pitch range setting for a human voice is already provided, along with a preprogrammed best recipe to customize the TTS model for your voice. Generate an API to integrate a customized TTS model into your application. Download a deployable package with a helm chart to run on any cloud or on-premises Kubernetes cluster. Then, automatically host your voice microservice with NVIDIA, or set it up with just one-line of code. Set up, customize, and deploy the Riva TTS model with intuitive no-code, end-to-end GUI workflows and no infrastructure configuration.
