Natural voice synthesis is an artificial intelligence technology that converts written text into lifelike spoken audio using natural-sounding voices. Unlike traditional robotic text-to-speech systems, modern synthesis technology mimics human tone, rhythm, and emotion, providing a more engaging and accessible audio experience.

TechClass integrates natural voice synthesis into its platform to enhance accessibility and learner engagement. This feature allows users to listen to lessons, quizzes, or educational materials instead of reading, supporting learners with visual impairments, reading difficulties, or those who prefer auditory learning. It also enables multilingual audio support, making content more inclusive and user-friendly for global learners.
