Understanding Greek GSM files
Standard Modern Greek, based on the Demotic variety spoken in Greece, is the form most speech recognition models are trained on. Cypriot Greek differs noticeably in pronunciation and vocabulary, and regional accents from Crete and northern Greece can also vary from the Athens standard.

Frequently asked questions
How to improve the accuracy of your Greek transcripts?
Start by improving the quality of the Greek 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 Greek GSM file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Greek 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 Greek 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 Cypriot Greek?
Sonix's Greek model is built around Standard Modern Greek, so Cypriot recordings can be transcribed, but dialect-heavy passages may need cleanup in the built-in editor.
Does Sonix output Greek transcripts in the Greek alphabet?
Yes, transcripts are produced in Greek script, and you can edit them in the browser and export to formats like DOCX, PDF, SRT, and VTT.
Can I add English subtitles to a Greek video?
Yes, after transcribing the Greek audio you can translate the transcript into English and export it as SRT or VTT subtitle files.
Trusted by professionals worldwide
I was amazed by your accuracy. What I used were not very good recordings. One with an American accent, another one Australian and many background noises. The transcript exceeded my expectations.
I loved my experience cause Sonix has a really good tutorial and it got the words from the audio pretty well. It really did it what I needed really fast, even if it was the first time using it.
