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

Voice biometrics involves utilizing an individual's voice as a distinct identifying feature for authentication and enhancing user interactions. This technology is known by several names, such as voice verification, speaker verification, speaker identification, and speaker recognition. There are two primary methods for implementing voice biometrics in real-world applications. The first method is Text Independent Voice Verification, which allows for authentication without the need for the user to speak a specific phrase. The second method, Text Dependent Voice Verification, requires the user to enroll by reciting a designated phrase, which, unlike a password, is not confidential. Furthermore, IDVoice supports both methods, allowing for flexibility based on individual requirements, and in certain cases, they can be integrated for improved security and accuracy. This adaptability makes voice biometrics a versatile tool in various authentication scenarios.
