Understanding Welsh RM 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 RM 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 RM file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Welsh RM file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from RM, 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 RM file play on my computer?
RM is a proprietary RealNetworks format that modern operating systems no longer support out of the box. You typically need RealPlayer, or a player like VLC that offers partial RM support.
Should I convert my RM files to a modern format?
For long-term preservation, converting to a widely supported format like MP4 is a reasonable step, since RM playback support continues to shrink. Keep the original file as well, because re-encoding a lossy format can reduce quality slightly.
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
It's incredibly fast, and it sets the timing for subtitles perfectly. I dread having to time everything myself, and with Sonix I can do that just by pressing Enter!
I'm very impressed about the accuracy. The transcript needs a little editing, but just minor correction. I think the interface is straightforward and user-friendly. I also like the audio-transcript matching playback functionality. I've been very deterred to use recording during my interviews because it takes a tremendous amount of time to transcribe.
