Description
Sonic 3.5 represents Cartesia's most advanced and fluid text-to-speech model, engineered for dynamic voice synthesis with an impressive latency of under 90 milliseconds and proficient in 42 languages. This model is adept at accurately adhering to transcripts, vocalizing confirmation codes, and interpreting heteronyms seamlessly without the need for any preprocessing, while also maintaining the expressiveness required for genuine conversations. It aims to provide speech of native quality across diverse languages, ensuring that audio clarity is prioritized in every voice output, thus eliminating the need for post-production corrections. Sonic 3.5 excels in delivering high-fidelity audio, making it an ideal choice for production environments where quality, speed, and reliability are essential. The model's engaging conversational style features effective pacing and a genuine emotional range, specifically calibrated for diverse support and agent transcripts. Moreover, it naturally articulates alphanumeric sequences—such as order numbers, phone numbers, IDs, and email addresses—in all supported languages, and its context-sensitive English pronunciation ensures that words like "read," "bass," and "bow" are pronounced correctly based on their textual context. This level of sophistication in voice generation not only enhances user experience but also establishes Sonic 3.5 as a leader in the field of text-to-speech technology.
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.
