Speech Intellect is the first real-time working speech-to-text/text-to-speech solution that employs entirely new AI-focused mathematical theory - Sense Theory. It considers the meaning of each word uttered by the customer. Our solution, based on the self-developed Sense-to-Sense algorithm, can realize the textual reproduction with tone and specific intonation. This solution can be easily integrated into various business scenarios, such as replicating character voices in video games, customer interaction in call centers, virtual dialogues on websites, and comfortable conversations in smart homes. Our algorithm uses Sense, differentiating it from algorithms used in other market solutions.
