Everything you need to know about SozAI transcription services
It depends on the language and on the recording. In our own test on 200 clean recordings of read speech in 10 languages (October 2026), SozAI got 1.8 % of words wrong in Spanish, 3.6 % in English and 5.5 % in Russian; Arabic and Kazakh did noticeably worse. Noise, people talking over each other, strong accents and names raise the error rate, so check anything you will quote against the audio — every line has a timestamp to jump to.
SozAI transcribes 99 languages, including English, Spanish, French, German, Chinese, Japanese, Arabic, Hindi, Russian and Portuguese. You do not need to choose one: the language of each recording is detected automatically.
Usually a couple of minutes. Over the last month, a recording of about one hour was ready a median of 1.3 minutes after it finished uploading, and nine in ten took under two minutes. Longer files take longer, and the app tells you when the transcript is ready.
Your audio travels over an encrypted connection to SozAI's servers. To make the transcript, the summary and the chat answers, the audio and text are processed by speech-recognition and AI providers acting on our instructions; the privacy policy names them. We do not sell your data or use your recordings to train models, and you can delete your transcripts or your whole account in the app.
We support all major audio and video formats including MP3, WAV, M4A, AAC, FLAC, OGG, MP4, MOV, AVI, and more. Maximum file size is 500MB per upload.
Yes. Every account gets 30 minutes of transcription once, with no credit card. That is enough to try SozAI on your own recordings before you decide.
Yes. You can edit a transcript in the app; the text is tied to the audio timeline, so you can jump to the moment you are correcting. Changes are saved to your account automatically.
Yes. SozAI labels each speaker in the transcript (Speaker A, Speaker B and so on), and you can rename the speakers so the transcript shows real names.
