Workflow
Record straight into the app, upload a file up to 500 MB, or paste a YouTube link. SozAI reads m4a, mp3, wav, aac, mp4 and mov.
Choose Mandarin or Cantonese and your character set, or leave detection on. Recordings that mix Chinese with English technical terms stay in a single transcript.
The transcript arrives with speaker labels and word timestamps. Search it, ask it questions, generate a summary in Chinese, or export SRT and VTT subtitles.
Field notes
Mandarin distinguishes syllables by pitch contour, so mā, má, mǎ and mà are four unrelated words. A tone error is a word error, not a pronunciation quirk, and compressed phone audio is exactly where tone contours degrade. This is the single biggest driver of accuracy differences between clean and noisy Chinese recordings.
Chinese is written without word boundaries. Before the transcript can be searched or time-aligned, the system has to decide where words start and end, and different segmentations of the same characters can be equally grammatical with different meanings. Search behaviour in Chinese transcripts depends entirely on getting this right.
They are not mutually intelligible in speech, and Cantonese has its own vocabulary, grammar and written characters. Treating Cantonese as accented Mandarin produces confident nonsense, so it is a separate target. Recordings that switch between them within one meeting remain the hardest case.
The same spoken sentence is written differently in mainland China than in Taiwan or Hong Kong, and the mapping is not always one to one. Choosing the wrong character set produces a transcript that is technically readable and immediately marks the document as foreign to its audience.

Short answers you can quote. Longer ones live in the sections above.
Yes, as a separate target rather than as an accent of Mandarin. The two are not mutually intelligible in speech and Cantonese has its own vocabulary and written forms, so selecting the right one matters more than it does for most dialect choices in other languages.
Yes. Both character sets are supported, and the choice affects the whole transcript. Because the mapping between them is not strictly one to one, picking the right one up front produces better output than converting afterwards.
Yes. Diarization runs on the audio rather than the language, so each speaker gets a label and every turn a timestamp. For 会议记录 this is what turns a recording into a document you can circulate rather than a wall of characters.
SozAI exports SRT and VTT in UTF-8 with word-level timing, so Chinese characters load correctly in YouTube, Premiere Pro, Final Cut Pro and DaVinci Resolve. Line breaking still deserves a human pass, since Chinese subtitle conventions differ from Latin-script ones.
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 price does not depend on the language. Current plans are listed on the pricing page.
