Description
The Cartesia Sonic-3 is an innovative real-time text-to-speech (TTS) model that produces highly realistic and expressive vocal outputs with minimal delay, allowing AI systems to engage in conversations that resemble human interactions. Utilizing a sophisticated state space model architecture, this technology provides superior speech quality while enabling audio generation to commence in as little as 40 to 100 milliseconds, creating a fluid conversational experience without noticeable pauses. Tailored specifically for conversational AI applications, Sonic serves as the vocal component for AI agents, transforming written text into speech that conveys a range of emotions, including excitement, empathy, and even laughter. With support for over 40 languages and the ability to localize accents, developers can create applications that maintain exceptional quality and accessibility for users around the globe. This versatility ensures that Sonic-3 not only meets the needs of various markets but also enhances user engagement through its lifelike voice capabilities.
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.
