About Japanese Transcription
Japanese is spoken by 128M+ people worldwide, primarily in Japan, Japanese diaspora (Brazil, USA, Australia). Japanese has no spaces between words, word segmentation is a layer on top of STT. Whisper achieves approximately 5–8 % CER on standard Japanese. The honorific speech levels (keigo) add vocabulary variation, though Whisper handles them reasonably in broadcast contexts.
Writing system: Japanese writing interleaves three scripts simultaneously: hiragana (grammar), katakana (foreign loanwords), and kanji (Chinese-origin logographs). Proficient text uses all three in every sentence.
