What is Inworld TTS?

Inworld TTS emerges as a state-of-the-art text-to-speech technology that delivers remarkably lifelike and context-sensitive speech synthesis, complete with sophisticated voice-cloning capabilities, all at a highly competitive price point. Its flagship model, TTS-1, is designed for real-time applications, featuring low-latency streaming that provides the initial audio output in approximately 200 milliseconds and encompasses a broad spectrum of languages, including English, Spanish, French, Korean, and Chinese, among others. Developers can choose between instant zero-shot voice cloning, which requires merely 5 to 15 seconds of audio input, or more comprehensive fine-tuned cloning, which allows for the incorporation of voice-tags to express emotion, style, and non-verbal signals, while also facilitating seamless language transitions without compromising the distinct voice identity. Additionally, for users desiring enhanced expressiveness and multilingual support, the TTS-1-Max model is currently available in preview, showcasing improved functionalities. The platform supports multiple access methods, such as APIs and portal options, and can function in streaming or batch processing modes, making it adaptable for a wide array of uses, including interactive voice assistants, gaming avatars, and custom audio branding projects. With its innovative features and flexibility, Inworld TTS is set to transform the landscape of synthetic voice interactions and enhance user experiences across various domains.

What is EVI 3?

Hume AI's EVI 3 signifies a significant leap forward in speech-language technology, enabling the real-time streaming of user speech to produce natural and expressive vocal replies. It strikes a balance between conversational latency and the high-quality output typical of our text-to-speech model, Octave, while matching the cognitive prowess of top LLMs that operate at similar velocities. Additionally, it integrates with reasoning models and web search capabilities, allowing it to "think both fast and slow," which aligns its intellectual functions with those found in the most advanced AI technologies. In contrast to conventional models that are limited to a select number of voices, EVI 3 can instantly create a wide variety of new voices and personas, engaging users with an extensive library of over 100,000 custom voices already featured on our text-to-speech platform, each infused with a unique inferred personality. No matter which voice is selected, EVI 3 is capable of expressing a rich array of emotions and styles, either implicitly or explicitly when requested, thus enhancing the overall user experience. This flexibility and sophistication position EVI 3 as an invaluable asset for crafting personalized and engaging conversational interactions, making it a powerful tool for various applications in the realm of communication technology.
