Understanding Welsh WAV 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 WAV 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 WAV file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Welsh WAV file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from WAV, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Welsh with Sonix:
Do I need to convert WAV to MP3 before transcribing?
No, WAV files can be uploaded and transcribed directly. Keeping the original WAV avoids the compression artifacts an MP3 conversion introduces, though the larger file may take longer to upload.
Why are my WAV files so large?
WAV stores uncompressed PCM audio, so CD-quality stereo uses roughly 10 MB per minute. Converting to a compressed format like FLAC or MP3 reduces the size if you need to save space after 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.
