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 Hume Audio Decisions API serves as a cloud-based solution tailored for developers focused on creating voice applications and teams analyzing sound and speech. This API processes audio recordings along with optional contextual information and user-generated inquiries, delivering structured probabilities for potential answers. The range of questions spans observable audio characteristics, such as the count of speakers and the presence of background noise, in addition to subjective assessments regarding tone, empathy, clarity, naturalness, and frustration levels. With these insights, teams can effectively evaluate support calls, assess the performance of voice agents and text-to-speech systems, label speech datasets, contrast different recordings, and pinpoint instances for escalation or further model training. This API seamlessly integrates as a decision-making layer with existing speech recognition and voice generation systems, enabling developers to incorporate its analytical scores and probabilities into their unique workflows. Access to the API is granted through Hume, and the pricing structure is determined by the number of audio clips, questions, and contextual tokens submitted. Additionally, the API's versatility allows for a wide range of applications in various industries, enhancing the overall user experience and operational efficiency.
