Understanding Welsh transcription

Who transcribes Welsh content?

Welsh-language broadcasters and podcast producers, Welsh Government bodies and local councils meeting bilingual service requirements, and universities researching Welsh-medium education regularly transcribe Welsh audio. Oral history projects and legal proceedings in Wales, where Welsh may be spoken in court, also generate Welsh recordings.

Welsh dialects and accents

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.

Where Welsh is spoken

Welsh is spoken in Wales, and by some in England, Argentina, Canada, and America.

Welsh transcription FAQ

Frequently asked questions about
Welsh subtitles

What's the difference between SRT and VTT subtitles?

SRT (SubRip) is the most widely compatible subtitle format, supported by most video players and platforms. VTT (WebVTT) is the HTML5 standard that supports styling and positioning. Sonix exports both formats so you can use whichever works best for your platform.

How do I add Welsh subtitles to YouTube?

After downloading your SRT file from Sonix, go to YouTube Studio, select your video, click 'Subtitles', then 'Add Language' and choose Welsh. Click 'Add' under subtitles and upload your SRT file. YouTube will automatically sync the subtitles with your video.

Can I customize the subtitle timing?

Yes! Sonix provides precision timing tools in the editor. You can adjust start and end times for each subtitle line, set line breaks, and fine-tune synchronization. Changes are reflected in real-time as you watch the video.

How accurate are Welsh subtitles?

Sonix delivers 85-99% accuracy for Welsh transcription depending on audio quality. Our timing algorithm ensures subtitles appear at exactly the right moment. You can review and edit in our browser-based editor before exporting.

Can I style my subtitles?

VTT format supports basic styling like bold, italic, and positioning. For more advanced styling (fonts, colors, backgrounds), you'll need to use your video editing software or the platform's subtitle customization features after uploading.

How many subtitles can I create?

There's no limit on the number of subtitle files you can create. Sonix charges per minute of audio/video transcribed, not per export. Create as many subtitle files as you need from a single transcription.

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.
