Understanding Urdu CAF files
Standard Urdu is based on the Delhi (Khari Boli) variety, while Dakhini Urdu is spoken across the Deccan region of southern India, including Hyderabad. Because most Pakistanis speak Urdu as a second language, accents are shaped by first languages such as Punjabi, Sindhi, Pashto, and Saraiki — useful context when transcribing interviews recorded across different regions.

Frequently asked questions
How to improve the accuracy of your Urdu transcripts?
Start by improving the quality of the Urdu CAF 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 Urdu CAF file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Urdu CAF file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from CAF, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Urdu with Sonix:
Why won't my CAF file play on Windows?
CAF is an Apple container that most Windows applications do not support natively. You can open it with a third-party player such as VLC, or convert it to WAV or MP3 for broader compatibility.
How large can a CAF file be?
CAF uses 64-bit file offsets, so there is no practical size limit and recordings can run for many hours. This is the main advantage over WAV and AIFF, which are capped at 4 GB.
Can Sonix transcribe Urdu audio and video files?
Yes. Upload your Urdu audio or video file, let Sonix transcribe it automatically, then review and edit the transcript in the browser-based editor before exporting.
Should I choose Urdu or Hindi for my recording?
Spoken colloquial Urdu and Hindi are largely mutually intelligible, so the practical difference is the output script. Choose Urdu for a Perso-Arabic script transcript and Hindi for Devanagari.
Does Urdu transcription handle Pakistani and Indian accents?
Urdu is spoken with regional accents across Pakistan and India, including Dakhini in the south. Sonix transcribes standard spoken Urdu, and the synchronized editor makes it straightforward to review and correct accent-heavy passages.
