Description

Amazon Polly is a service designed to convert written text into realistic speech, enabling the development of applications that can communicate vocally and fostering the creation of innovative speech-enabled products. Utilizing state-of-the-art deep learning technologies, Polly's Text-to-Speech (TTS) service produces natural-sounding human voices. With a variety of lifelike voices available in numerous languages, developers can create speech-enabled applications that are functional in diverse global markets. Beyond the Standard TTS voices, Amazon Polly also provides Neural Text-to-Speech (NTTS) voices, which enhance speech quality significantly through a novel machine learning technique. In addition, Polly's Neural TTS supports two distinct speaking styles: a Newscaster style designed for news narration and a Conversational style that is perfect for interactive communication scenarios such as telephony. This flexibility allows developers to tailor the auditory experience to fit their specific application needs.

Description

Hume AI's EVI 3 represents a cutting-edge advancement in speech-language technology, seamlessly streaming user speech to create natural and expressive verbal responses. It achieves conversational latency while maintaining the same level of speech quality as our text-to-speech model, Octave, and simultaneously exhibits the intelligence comparable to leading LLMs operating at similar speeds. In addition, it collaborates with reasoning models and web search systems, allowing it to “think fast and slow,” thereby aligning its cognitive capabilities with those of the most sophisticated AI systems available. Unlike traditional models constrained to a limited set of voices, EVI 3 has the ability to instantly generate a vast array of new voices and personalities, engaging users with over 100,000 custom voices already available on our text-to-speech platform, each accompanied by a distinct inferred personality. Regardless of the chosen voice, EVI 3 can convey a diverse spectrum of emotions and styles, either implicitly or explicitly upon request, enhancing user interaction. This versatility makes EVI 3 an invaluable tool for creating personalized and dynamic conversational experiences.
