Description

Gemini 3.8 Flash TTS is a generative text-to-speech model from Google designed for expressive voice creation, character design, dialogue direction, and multilingual audio production. Instead of limiting users to fixed voice presets, the model can create entirely new vocal identities from natural-language descriptions. Developers and creators can specify attributes such as accent, role, timbre, speaking style, pacing, and other voice characteristics across more than 100 languages and dialects. The model also offers access to more than 2,000 production-ready voices and supports voice replication from a short authorized audio sample. Performance controls allow users to direct individual lines with stage directions, pacing instructions, dialect shifts, emotional cues, and conversational backchanneling. Gemini 3.8 Flash TTS supports long-form generation while maintaining voice consistency, making it suitable for podcasts, audiobooks, localization, and other extended audio projects. Native two-speaker scene support lets users create multi-turn conversations from a single script while preserving distinct voices and natural turn-taking. Google includes consent verification, SynthID watermarking, and C2PA credentials to provide greater transparency and safeguards around generated and replicated voices. Gemini 3.8 Flash TTS can be used through Google AI Studio and the Gemini API and is intended for developers, creators, enterprises, media companies, and teams building expressive speech experiences.

Description

Inworld TTS stands out as a cutting-edge text-to-speech solution that provides exceptionally realistic and context-aware speech synthesis alongside advanced voice-cloning features, all at an incredibly affordable price. Its leading model, TTS-1, is tailored for real-time usage, boasting low-latency streaming capabilities—where the first audio segment is available in about 200 milliseconds—and supports a wide array of languages such as English, Spanish, French, Korean, Chinese, and several others. Developers have the flexibility to utilize instant zero-shot voice cloning, requiring only 5 to 15 seconds of audio input, or opt for more detailed fine-tuned cloning, enabling the addition of voice-tags that convey emotion, style, and non-verbal cues, while also allowing for language switching without losing the unique voice identity. For those seeking even greater expressiveness and multilingual capabilities, the TTS-1-Max model is currently in preview, offering enhanced features. The platform accommodates various access methods, including API and portal options, and can operate in either streaming or batch modes, making it suitable for a diverse range of applications such as interactive voice agents, gaming characters, and bespoke audio branding experiences. With its versatility and advanced technology, Inworld TTS is poised to revolutionize how we interact with synthetic voices.
