What Is a Text-To-Speech Tool?
Text-to-speech (TTS), or speech or voice synthesis, is a transformative and assistive AI and machine learning technology that harnesses the power of AI and ML algorithms to convert written scripts and text-based documents into natural-sounding speech.
TTS tools use AI and ML text-to-audio and audio-to-text conversion techniques to transform written words and text-based scenarios into multilingual speech and spoken audio.
Text-to-speech technology is an ideal tool to transform written script into downloadable, shareable, and editable auditory content across various formats, including MP3, OGG, WAV, etc. Thanks to AI’s ability to develop multilingual voice models, TTS technology overcomes language barriers, making your audio and video content more available and accessible worldwide.
Some of the latest text-to-speech developments include real-time text-to-audio, expressive TTS, and AI neural TTS.
TTS software providers develop advanced AI-generated voice models using deep learning and neural networks to analyze, process, and interpret vast amounts of audio data. They focus on capturing the very essence and nuances of human speech, building contextually aware voice models that can perfectly mimic and replicate human speech, including emotions, rhythm, pronunciation, intonation, tone, voice style, etc.
An English online TTS tool can read aloud books, articles, website content, and PDFs using hyper-realistic AI voice models. Online TTS tools let you use their AI-generated multilingual voices and other features for free directly in your browser without installing software on your computer.
