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 closed captions

What's the difference between closed captions and subtitles?

Closed captions include all audio elements (dialogue, sound effects, music cues) for deaf and hard-of-hearing viewers. Subtitles typically only include dialogue and are meant for viewers who can hear but don't understand the spoken language. Sonix can create both.

Are Sonix captions ADA compliant?

Yes. Sonix generates captions that meet ADA (Americans with Disabilities Act), Section 508, and WCAG 2.1 accessibility requirements. Our captions include accurate timing, proper synchronization, and support for required caption formats.

Can I add sound effect descriptions to captions?

Yes! In the Sonix editor, you can add non-speech audio descriptions like [music playing], [applause], or [door closes]. These descriptions help deaf and hard-of-hearing viewers understand the full audio context.

How accurate are Welsh closed captions?

Sonix delivers 85-99% accuracy for Welsh captioning depending on audio quality. Clear audio with minimal background noise achieves the best results. You can review and edit captions in our browser-based editor.

What platforms support closed captions?

All major video platforms support closed captions including YouTube, Vimeo, Facebook, Twitter, LinkedIn, and Wistia. Sonix exports SRT and VTT formats compatible with all these platforms and more.

Can I burn captions into my video?

Yes! Sonix offers a burn-in feature that permanently embeds captions into your video file. This is useful for social media where closed captions may not display automatically. See our burn-in subtitles service for more details.

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.
