Understanding Persian GSM 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 GSM 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 GSM file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Persian GSM file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from GSM, 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 GSM file play on my computer?
GSM is a telephony codec that many consumer media players do not decode by default. Players such as VLC can open it, or you can convert the file to WAV or MP3 for broader compatibility.
Is telephone-quality GSM audio suitable for transcription?
GSM was designed specifically for human speech at an 8 kHz sample rate, so clear voice recordings generally transcribe well. As with any phone recording, heavy background noise or overlapping speakers reduces clarity.
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.
