Speech Recognition

Overview

Speech Recognition

The Bailing ASR version, updated in June 2026, fully supports the seven major dialect systems of traditional Chinese (Mandarin/Wu/Xiang/Gan/Hakka/Min/Yue) and is compatible with over 20 regional Mandarin accents. It features specific optimizations for the rhythm, meter, and literary expression characteristics of classical Chinese poetry, improving the accuracy of poetry recognition and making it suitable for cultural heritage, educational explanations, and audiobooks. Improved punctuation prediction and text normalization capabilities make the output text more consistent with written expression habits; numbers, dates, and amounts are automatically converted to standard formats, enhancing readability and professionalism. The language support has been expanded to include English, Japanese, Korean, Vietnamese, Thai, Indonesian, Malay, Filipino, Hindi, Arabic, French, German, Spanish, Portuguese, Russian, Italian, Dutch, Swedish, Danish, Finnish, Norwegian, Greek, Polish, Czech, Hungarian, Romanian, Bulgarian, Croatian, and Slovak, totaling 30 languages. It supports contextualization capabilities and can transcribe audio up to 5 minutes in length.
