Hakka TTS is currently under development and coming soon. This article introduces the linguistic features and cultural value of Hakka. Stay tuned for the official release. To explore other supported dialects, check our [Getting Started Guide](/en/blog/getting-started-with-dialect-tts).

What is Hakka?

Hakka is one of the seven major Chinese dialect groups, primarily spoken in northeastern Guangdong, western Fujian, southern Jiangxi, Taiwan, and throughout Southeast Asia. With approximately 40 million speakers worldwide, including diaspora communities across five continents, Hakka is one of the most globally influential Chinese dialects.

A "Living Fossil of Ancient Chinese"

Linguists call Hakka a "living fossil of ancient Chinese" because it preserves numerous phonetic features from Middle Chinese:

  • Complete entering tone system
  • Ancient consonant pronunciations
  • Conservative vowel system
  • Rhyme patterns matching Tang and Song dynasty poetry
Learning Hakka is like opening a window to ancient China. Reading classical poetry in Hakka often reveals the original rhyme schemes better than Mandarin does.
