Learn Chinese & Check Pronunciation! How to Use Free Text-to-Speech Ondoku
Aug. 28, 2026
Hello, thank you for always using Ondoku.
English uses "phonetic characters" that represent sounds, so you can generally imagine the pronunciation, but that is not the case with Chinese.
Moreover, even if the characters are the same as in Japanese, the pronunciation in Chinese and Japanese is different. Furthermore, since Chinese is a tonal language, the "four tones" can result in completely different meanings and words.
Hearing this, it feels like an extremely difficult language...
However, since Japanese people know kanji, they can understand the meaning if the communication is text-only.
By taking advantage of this, Japanese people are at an overwhelming advantage in learning Chinese compared to people from other countries.
That's why you want to master pronunciation and speak with Chinese people in Chinese.
A common trap Japanese people fall into when having a conversation in Chinese is that "the meaning is not conveyed because my Chinese pronunciation is bad."
