Understanding Basque OPUS files
Basque has five main dialect groups in the modern classification, including Biscayan, Gipuzkoan, and the more divergent Zuberoan (Souletin) spoken in France. Most modern media, education, and broadcast content uses Euskara Batua (Standard Basque), the standardized form that speech recognition handles most reliably.

Frequently asked questions
How to improve the accuracy of your Basque transcripts?
Start by improving the quality of the Basque OPUS 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 Basque OPUS file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Basque OPUS file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from OPUS, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Basque with Sonix:
Why won't my OPUS file play on my computer?
Older media players and some built-in OS players lack Opus support. Opening the file in VLC or a modern web browser, or converting it to MP3 or WAV, usually resolves the issue.
Are WhatsApp voice messages OPUS files?
Yes, WhatsApp exports voice notes as .opus files. You can upload them for transcription directly without converting them first.
Can Sonix transcribe Basque audio and video?
Yes. Upload your Basque audio or video file, select Basque as the language, and Sonix generates a transcript you can edit in the browser and export to formats like DOCX, PDF, and SRT.
Does Basque transcription work for regional dialects?
Automated transcription performs best with Euskara Batua (Standard Basque), the form used in most broadcast and educational content. Recordings in traditional dialects such as Zuberoan may require more manual correction in the editor.
What if my Basque recording mixes in Spanish or French?
Code-switching with Spanish or French is common in Basque speech. Transcribe in the dominant language of the recording, then use the built-in editor to correct any mixed-language passages.
