SozAI reads m4a, mp3, wav, aac, mp4 and mov. 2. 02 ### Set Japanese, or let it detect Choose Japanese, or leave detection on. Recordings that mix Japanese with English technical vocabulary stay in a single transcript. 3. 03 ### Read, search and export The transcript arrives with speaker labels and word timestamps. Search it, ask it questions, generate a summary in Japanese, or export SRT and VTT subtitles. Field notes ## What makes Japanese hard to transcribe ### There are no spaces to fall back on Japanese is written without word boundaries, so the transcript has to decide where words begin and end before it can time-align them or make them searchable. Two segmentations of the same sound sequence can both be valid Japanese with different meanings. This is why word-level timestamps in Japanese are a harder claim than in a spaced language. ### Three scripts, and the choice between them is meaningful The same word can be written in kanji, hiragana or katakana, and the choice signals register, emphasis or foreignness. Writing everything in hiragana is technically readable and looks like a child wrote it; over-applying kanji reads as stiff. A usable Japanese transcript has to make the same choices a person would. ### Homophones are everywhere and only context separates them Japanese has an unusually dense field of homophones — kikan, koutai, seikou each map to many different kanji spellings. The audio contains no information about which one was meant. Selecting the right characters is a language-modelling problem, and it is where most remaining Japanese transcription errors live. ### Keigo changes the whole sentence Honorific, humble and plain registers use different verbs, not just different endings, and Japanese business recordings move between them constantly. A transcript that flattens keigo is not merely less polite — it misrepresents who was deferring to whom, which matters in a meeting record.

Longer ones live in the sections above. Does the transcript use kanji, or only kana? It uses kanji, hiragana and katakana the way a person would write them, rather than defaulting to all-kana output. This is what makes the transcript readable at normal speed and searchable — kana-only Japanese is technically decodable but nobody reads documents that way. Can it separate speakers in a Japanese meeting? Yes. Diarization runs on the audio rather than the language, so each speaker gets a label and every turn a timestamp. For 議事録 and interview records this is what turns a recording into a document you can circulate. How accurate is it on business Japanese? Accuracy is highest on clear, single-speaker standard Japanese and drops on fast overlapping conversation, heavy Kansai speech and poor phone audio. The most common residual errors are homophone choices — the sentence structure is right and one word is written with the wrong kanji, so proofreading is worth budgeting for. Are Japanese subtitles exported correctly? SozAI exports SRT and VTT in UTF-8 with word-level timing, so Japanese text loads correctly in YouTube, Premiere Pro, Final Cut Pro and DaVinci Resolve. Line breaking still deserves a human pass, since Japanese subtitle conventions differ from Latin-script ones. How much does Japanese transcription cost? Every account gets 30 minutes per month free without a card. Beyond that SozAI is a flat monthly subscription with a shared pool of minutes, and the language does not change the price. Current plans are listed on the pricing page.
