What is Text-to-Speech?

Text-to-Speech

Quick Answer

This technology converts written text into spoken words using computer-generated voices. It allows devices to read text aloud, making information more accessible.

Overview

Text-to-Speech (TTS) is a technology that enables computers to convert written text into spoken language. It works by analyzing the text and using algorithms to generate speech sounds that mimic human voices. TTS systems often use artificial intelligence to improve the naturalness and clarity of the speech, making it sound more human-like. The process begins with text input, which is then processed by the TTS software. This software breaks down the text into smaller components, such as words and phonemes, and applies linguistic rules to determine how to pronounce them. The final output is a digital voice that reads the text aloud, which can be customized in terms of speed, pitch, and tone. Text-to-Speech technology is important because it enhances accessibility for individuals with visual impairments or reading difficulties. For example, screen readers use TTS to help blind users navigate websites by reading the content aloud. TTS is also used in applications like virtual assistants, navigation systems, and language learning tools, showcasing its versatility in everyday life.
