Experience Korean TTS (Text To Speech) Firsthand

What is Korean TTS?

Definition and Principles of TTS Technology

TTS is a technology that converts text into speech.

Simply put, it's when a computer reads aloud the text we type!

It utilizes cutting-edge deep learning technology to learn from vast amounts of voice data, creating natural pronunciations and intonations based on this learning.

Why are there many good English TTS services but many Korean TTS services have awkward AI voices?

This is actually due to differences in training data.

English has thousands of hours of open-source voice data available, while Korean has relatively less.

Additionally, Korean is a more challenging language for AI to learn due to its final consonants, phonological rules, and complex honorific system!
