Understanding Persian OPUS files
Persian has three major national varieties: Iranian Persian (Farsi), Dari in Afghanistan, and Tajik in Tajikistan and Uzbekistan, which differ in vowel pronunciation, vocabulary, and loanwords. Colloquial spoken Persian, especially the Tehrani register, also diverges noticeably from formal written Persian in verb endings and contractions, which matters when converting speech to standard written text.

Frequently asked questions
How to improve the accuracy of your Persian transcripts?
Start by improving the quality of the Persian OPUS file that you upload to Sonix. Please use high quality recording equipment, recording in a quiet environment, and ensure that your speakers are speaking clearly to ensure that your transcript is as accurate as possible.
Any advice for the Persian OPUS file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Persian OPUS file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from OPUS, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Persian with Sonix:
Why won't my OPUS file play on my computer?
Older media players and some built-in OS players lack Opus support. Opening the file in VLC or a modern web browser, or converting it to MP3 or WAV, usually resolves the issue.
Are WhatsApp voice messages OPUS files?
Yes, WhatsApp exports voice notes as .opus files. You can upload them for transcription directly without converting them first.
Can Sonix transcribe Dari or Afghan Persian audio?
Yes. Dari is a national variety of Persian, and Persian-language audio from Afghanistan can be uploaded, transcribed, edited, and exported like any other supported language.
Is Farsi the same as Persian for transcription purposes?
Farsi is the local name for Persian as spoken in Iran, so selecting Persian is the correct choice for Farsi audio. The same selection covers Iranian Persian recordings from media, interviews, and meetings.
Does Persian transcription handle right-to-left text?
Yes. Persian transcripts are produced in the right-to-left Perso-Arabic script, and you can edit them in the browser and export to formats such as Word, SRT, and VTT.
Trusted by professionals worldwide
Gobsmackingly amazing! As a software developer of 40 years I know quality when I see it. An amazing product and a pretty damn good web-site to back it all up also. Totally staggered at the accuracy, especially when multiple voices contribute to a meeting.
I am very happy to have found a transcription service that provides such a high percentage of perfect content.
