Understanding Bengali AAC files
Standard Bengali comes in two closely related national varieties: the Dhaka-influenced standard used in Bangladesh and the Kolkata-based standard used in West Bengal, India, which differ in pronunciation and some vocabulary. Regional varieties such as Sylheti and Chittagonian diverge so strongly that many linguists classify them as separate languages, so they behave differently from standard Bengali in speech recognition.

Frequently asked questions
How to improve the accuracy of your Bengali transcripts?
Start by improving the quality of the Bengali AAC 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 Bengali AAC file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Bengali AAC file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from AAC, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Bengali with Sonix:
What is the difference between AAC and M4A files?
Both typically contain the same AAC-encoded audio; the difference is packaging. A .aac file is a raw ADTS stream, while a .m4a file wraps the audio in an MPEG-4 container that supports metadata such as tags, artwork, and chapters.
Why won't my AAC file open in some apps?
Raw .aac files are a bare audio stream without a standard container, so some players and editors that expect MP4/M4A files cannot read them. Renaming the extension does not fix this — remux or convert the file into an M4A or MP3 instead.
Can Sonix transcribe both Bangladeshi and Indian Bengali?
Yes. Sonix's Bengali model handles standard Bengali as spoken in both Bangladesh and West Bengal, India; you upload your audio or video, select Bengali, and then review and edit the transcript in the browser.
Does Sonix output Bengali transcripts in the Bengali script?
Yes. Transcripts are produced in the native Bengali (Bangla) script, and you can edit them in the online editor and export to formats such as DOCX, PDF, SRT, and VTT.
Can Sonix transcribe Sylheti or Chittagonian recordings?
Sonix's Bengali model is trained on standard Bengali, and Sylheti and Chittagonian diverge enough that they are often considered separate languages. Recordings in those varieties may need more manual correction in the editor.

I love how accurate the software is! The way you can play audio as you go through the text or click on any part of the text to hear the audio is amazing.
I wouldn't have been able to pass my course without this technology. I was able to get two A's thanks to this program!
