TTS stands for Text-to-Speech. It is a technology that converts written text into spoken words. TTS systems take input text and use synthetic voices to produce spoken audio. These systems are widely used in various applications, including accessibility features for visually impaired individuals, automated customer service systems, navigation systems, and more.
The process involves several steps:
Text Analysis: The input text is analyzed to understand the structure, punctuation, and context. This analysis helps in determining how the text should be spoken to sound natural.
Text-to-Phoneme Conversion: The system converts the written words into phonemes, which are the smallest units of sound that make up spoken language.
Prosody Generation: Prosody refers to the rhythm, pitch, and tempo of speech. TTS systems generate prosody to make the synthetic speech sound more natural and expressive.
Voice Synthesis: The synthesized voice is generated based on the phonetic and prosodic information. This is what produces the final spoken output.
TTS technology has made significant advancements over the years, with more natural-sounding voices and improved linguistic processing. It finds applications in various domains, enhancing accessibility and user experience in software, devices, and online services.
