Text to speech (TTS) is an AI task that involves audio generation from text. TTS is a technology that converts text into spoken audio using natural sounding voices. TTS can read aloud any text data, such as PDFs, websites, books, emails, etc., and provide an auditory format for accessing written content. TTS can be helpful for anyone who needs to listen to text data for various reasons, such as accessibility, convenience, multitasking, learning, entertainment, etc. TTS uses different techniques and models to generate speech from text data, such as:
Concatenative synthesis: Combining pre-recorded segments of human speech based on the phonetic units of the text.
Parametric synthesis: Generating speech signals from acoustic parameters derived from the text using statistical models.
Neural synthesis: Using deep neural networks to learn the mapping between text and speech features and produce high-quality speech signals.
Expressive synthesis: Adding emotions or styles to the speech output to make it more natural and engaging. Reference: : Text-to-Speech AI: Lifelike Speech Synthesis | Google Cloud, Text-to-speech synthesis - Wikipedia
