Mandarin vs Cantonese
Standard Mandarin (Putonghua, 普通话) — official in mainland China and Taiwan — transcribes most accurately. Cantonese (粵語) — spoken in Hong Kong, Macau, and Guangdong — is supported but with lower accuracy due to less training data. The output language matches input.
Simplified vs traditional characters
Mainland China and Singapore use simplified characters (简体). Taiwan, Hong Kong, and Macau use traditional (繁體). The output uses the variety appropriate to the speaker (typically follows the speaker's dialect/origin).
Use cases
