Understanding Welsh MP3 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 MP3 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 MP3 file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Welsh MP3 file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from MP3, 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 MP3 bitrate affect transcription quality?
It can. Files encoded at 128 kbps or higher preserve more speech detail, while heavily compressed recordings below about 96 kbps may introduce artifacts that make words harder to recognize.
How do I turn an MP3 recording into SRT subtitles?
Upload the MP3, generate a transcript, adjust the text and timings as needed, and export the result in SRT or VTT caption format.
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.
