Understanding Hindi GSM files
Standard Hindi is based on the Khari Boli dialect of the Delhi region, but everyday speech across northern India shades into related varieties such as Awadhi, Braj, and Bhojpuri. Spoken Hindi also overlaps heavily with Urdu, and urban speakers frequently mix in English ("Hinglish"), so recordings often contain more than one register.

Frequently asked questions
How to improve the accuracy of your Hindi transcripts?
Start by improving the quality of the Hindi 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 Hindi GSM file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Hindi 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 Hindi 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 Hindi audio that mixes in English words?
Yes, you can upload Hindi audio and video files and Sonix will transcribe them; because Hindi speakers often switch into English mid-sentence, it is worth reviewing mixed-language passages in the built-in editor before exporting.
Does Sonix output Hindi transcripts in Devanagari script?
Yes, Hindi transcripts are produced in Devanagari, and you can edit them in the browser and export to formats like DOCX, PDF, SRT, and VTT.
Should I choose Hindi or Urdu for my recording?
Spoken Hindi and Urdu overlap heavily, but they are separate language selections with different scripts, so choose the one that matches your recording to get the transcript in the correct writing system.
Trusted by professionals worldwide
I had been using Dragon voice recognition software, but Sonix eliminates that step all together. I absolutely love Sonix.
I have been a dialogue system researcher for half a decade now. I had build my own app for doing the transcriptions. Sonix was clearly better than what I had. I made the switch!
