Description

A feature within the Speech service that confirms and recognizes individual speakers enhances customer interactions. By facilitating seamless and secure experiences, the solution improves customer satisfaction through efficient verification methods. Utilizing voice as a means of authentication allows for smooth and secure engagements across various platforms, including web applications and call centers. The speaker verification process can utilize either specific passphrases or open-ended voice input to achieve its goal. Furthermore, it offers significant advantages in scenarios involving multiple speakers, allowing the system to identify individuals among a group of enrolled users. This functionality supports personalized interactions by attributing speech to specific speakers and enhances multiuser voice recognition capabilities. In essence, this feature not only streamlines the verification process but also enriches the overall engagement experience for customers.

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.
