Description

Easily and efficiently develop voice-enabled applications with the Speech SDK, which allows for precise speech-to-text transcription, the generation of realistic text-to-speech voices, and the translation of spoken audio while also incorporating speaker recognition features. By utilizing Speech Studio, you can design customized models that suit your specific application needs, benefiting from advanced speech recognition, lifelike voice synthesis, and award-winning capabilities in speaker identification. Your data remains private, as your speech input is not recorded during processing, and you can create unique voices, expand your base vocabulary with specific terms, or develop entirely new models. The Speech SDK can be deployed in various environments, whether in the cloud or through edge computing in containers, enabling rapid and accurate audio transcription across more than 92 languages and their respective variants. Furthermore, it provides valuable customer insights through call center transcriptions, enhances user experiences with voice-driven assistants, and captures critical conversations during meetings. With options for text-to-speech, you can build applications and services that engage users conversationally, selecting from an extensive array of over 215 voices in 60 different languages, making your projects more dynamic and interactive. This flexibility not only enriches the user experience but also broadens the scope of what can be achieved with voice technology today.

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.
