What is Grok Text to Speech (TTS)?

Grok Text to Speech (TTS) is a standalone audio API designed to empower developers in swiftly generating natural and engaging speech from text. Leveraging the same technology that underpins Grok Voice, Tesla vehicles, and Starlink services, this API facilitates the seamless integration of high-quality voice synthesis across a diverse range of applications, such as digital assistants, voice agents, podcasts, accessibility tools, and customer interaction systems. With Grok TTS, users can transform extensive written content into audio using a REST API or generate speech in real-time via a WebSocket API, providing the versatility required for both batch processing and dynamic conversational tasks. The API focuses on delivering expressive and nuanced speech, instead of flat narration, by offering refined control through intuitive inline and wrapping speech tags. By utilizing these tags, developers can add emotional depth and natural prosody to the speech output, ensuring a more authentic delivery without the need for cumbersome markup. This capability positions Grok TTS as a critical asset for enhancing user interaction and fostering more engaging experiences. Furthermore, its ease of use and accessibility make it an attractive choice for developers looking to improve the auditory aspects of their applications.

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.
