Understanding Bengali WEBM 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 WEBM 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 WEBM file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Bengali WEBM file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from WEBM, 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 WebM file open in my video editor?
Many desktop editing applications do not include VP8/VP9 decoders, so WebM files may need conversion to MP4 before importing, even though browsers and players like VLC handle them natively.
How do I get subtitles from a WebM video?
Upload the WebM file for transcription, review and edit the resulting transcript, then export it as an SRT or VTT caption file that most video players and platforms accept.
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.
Trusted by professionals worldwide
Thank you for this amazing application and program which really saved my life.
I've tried several different digital software packages and nothing has even approached giving me a usable transcription. The results from Sonix are the best I've seen. And fast. I'd given up on having my recordings automatically transcribed. No more.
