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
The gpt-4o-mini-realtime-preview model is a streamlined and economical variant of GPT-4o, specifically crafted for real-time interaction in both speech and text formats with minimal delay. It is capable of processing both audio and text inputs and outputs, facilitating “speech in, speech out” dialogue experiences through a consistent WebSocket or WebRTC connection. In contrast to its larger counterparts in the GPT-4o family, this model currently lacks support for image and structured output formats, concentrating solely on immediate voice and text applications. Developers have the ability to initiate a real-time session through the /realtime/sessions endpoint to acquire a temporary key, allowing them to stream user audio or text and receive immediate responses via the same connection. This model belongs to the early preview family (version 2024-12-17) and is primarily designed for testing purposes and gathering feedback, rather than handling extensive production workloads. The usage comes with certain rate limitations and may undergo changes during the preview phase. Its focus on audio and text modalities opens up possibilities for applications like conversational voice assistants, enhancing user interaction in a variety of settings. As technology evolves, further enhancements and features may be introduced to enrich user experiences.
