Description

Gemini 3.8 Flash-Lite TTS is an expressive text-to-speech model from Google optimized for high-volume, cost-efficient speech generation. It is designed for workloads such as global dubbing, large-scale audio content production, localization, and conversational voice agents. Users can control characteristics such as tone, pacing, emphasis, and expressive nuance to shape how generated speech is delivered. Line-by-line direction allows scripts to include performance instructions and natural speech cues rather than producing uniformly spoken narration. The model supports long-form generation and is designed to preserve voice quality, natural pacing, and character consistency across extended audio. Native two-speaker staging allows developers and creators to generate multi-turn conversations while keeping speakers distinct and maintaining natural turn-taking. Scripted cues can introduce laughs, sighs, gasps, and listening responses such as “mhm” or “yeah” to make dialogue more conversational. Gemini 3.8 Flash-Lite TTS supports more than 100 languages and is designed for multilingual audio experiences at global scale, while generated Gemini Audio output includes SynthID watermarking for transparency. Developers can access the model through Google AI Studio and the Gemini API, with integration into Google Vids and planned API availability through Gemini Enterprise.

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.
