Learn Chinese & Check Pronunciation! How to Use Ondoku, a Free TTS Service
Aug. 7, 2026
Hello, thank you for always using Ondoku.
English uses "phonetic characters" that represent pronunciation, so you can generally imagine the sound, but that is not the case with Chinese.
Moreover, even for the same kanji used in Japanese, the pronunciation is different in Chinese and Japanese. Furthermore, because Chinese is a tonal language, the "four tones" can result in completely different meanings and words.
Hearing this makes it feel like a language with an extremely high level of difficulty...
However, since Japanese people know kanji, they can understand the meaning through text-based communication.
By taking advantage of this, Japanese people have an overwhelming advantage in mastering Chinese compared to people from other countries.
That is why you want to master the 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 poor."
