Cantonese Language Data
Cantonese, spoken by over 80 million people, is a major Sinitic language used widely across Hong Kong, Macau, Guangdong, and diaspora communities globally. Its tonal system (with six to nine tones depending on analysis), rich syllable structure, and unique vocabulary make it distinct from Mandarin. Cantonese is written both in Standard Chinese and in unique Cantonese-specific characters, creating additional complexity for NLP tasks. High-quality Cantonese datasets significantly improve ASR, sentiment analysis, chatbot development, and tone-sensitive speech technologies.
