Understanding Welsh GSM files
The main spoken split is between northern and southern Welsh, which differ in vowel pronunciation and everyday vocabulary (for example, llefrith versus llaeth for milk). Colloquial speech also diverges noticeably from formal literary Welsh, and a small Patagonian Welsh community survives in Argentina.

Frequently asked questions
How to improve the accuracy of your Welsh transcripts?
Start by improving the quality of the Welsh 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 Welsh GSM file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Welsh 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 Welsh 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 Welsh audio and video?
Yes. Upload your Welsh recording, select Welsh as the language, and Sonix generates a transcript you can edit in the browser and export to formats such as DOCX, PDF, and SRT.
Does Welsh transcription handle both north and south Wales accents?
Sonix transcribes Welsh spoken across regions, though vocabulary and pronunciation differ between northern and southern Welsh, so it is worth reviewing regional words in the built-in editor.
Can Sonix transcribe recordings that mix Welsh and English?
Each file is transcribed in one selected language, so choose the language that dominates the recording and correct mixed-language passages in the editor.
Trusted by professionals worldwide
Sonix is simple and very easy to use and the results were very nearly perfect. I would definitely recommended the site to anyone who asks me.
Was using another software before, but their prices went up. Your prices are better and the transcription seems more accurate. I also like that you automatically take out all of the filler words - um, you know, etc.
