Description

Gemini 3.8 Flash TTS is a generative text-to-speech model from Google designed for expressive voice creation, character design, dialogue direction, and multilingual audio production. Instead of limiting users to fixed voice presets, the model can create entirely new vocal identities from natural-language descriptions. Developers and creators can specify attributes such as accent, role, timbre, speaking style, pacing, and other voice characteristics across more than 100 languages and dialects. The model also offers access to more than 2,000 production-ready voices and supports voice replication from a short authorized audio sample. Performance controls allow users to direct individual lines with stage directions, pacing instructions, dialect shifts, emotional cues, and conversational backchanneling. Gemini 3.8 Flash TTS supports long-form generation while maintaining voice consistency, making it suitable for podcasts, audiobooks, localization, and other extended audio projects. Native two-speaker scene support lets users create multi-turn conversations from a single script while preserving distinct voices and natural turn-taking. Google includes consent verification, SynthID watermarking, and C2PA credentials to provide greater transparency and safeguards around generated and replicated voices. Gemini 3.8 Flash TTS can be used through Google AI Studio and the Gemini API and is intended for developers, creators, enterprises, media companies, and teams building expressive speech experiences.

Description

Utilize an API that leverages Google's advanced AI technologies to transform text into natural-sounding speech. With the foundation laid by DeepMind’s expertise in speech synthesis, this API offers voices that closely resemble human speech patterns. You can choose from an extensive selection of over 220 voices in more than 40 languages and their various dialects, such as Mandarin, Hindi, Spanish, Arabic, and Russian. Opt for the voice that best aligns with your user demographic and application requirements. Additionally, you have the opportunity to create a distinctive voice that embodies your brand across all customer interactions, rather than relying on a generic voice that might be used by other companies. By training a custom voice model with your own audio samples, you can achieve a more unique and authentic voice for your organization. This versatility allows you to define and select the voice profile that best matches your company while effortlessly adapting to any evolving voice demands without the necessity of re-recording new phrases. This capability ensures your brand maintains a consistent audio identity that resonates with your audience.
