Understanding Bengali GSM 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 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 Bengali GSM file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Bengali 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 Bengali 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 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.
