Understanding Welsh MK3D 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 MK3D 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 MK3D file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Welsh MK3D file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from MK3D, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Welsh with Sonix:
Does the 3D video affect transcription of an MK3D file?
No. Transcription uses only the audio track, so the stereoscopic layout stored in the StereoMode field has no effect on the resulting text.
Why won't my MK3D file play on my computer?
Many default media players do not recognize the .mk3d extension or lack stereoscopic support. Players that handle Matroska files, such as VLC, can usually open them, though the video may display as 2D without 3D-capable hardware.
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.
