Understanding French OPUS files
French varies noticeably between Metropolitan (European) French, Canadian French (including Québécois, with distinct vowel sounds and vocabulary), and the many African varieties spoken in countries like Senegal, Ivory Coast, and the Democratic Republic of the Congo. Belgian and Swiss French are close to the Metropolitan standard but use different number words (septante, nonante), which matters when verifying figures in a transcript.

Frequently asked questions
How to improve the accuracy of your French transcripts?
Start by improving the quality of the French 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 French OPUS file that I upload?
Yes, please do not over-compress or over-filter the audio track of your French 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 French 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 Canadian French?
Yes. Sonix transcribes French audio from Canada as well as Europe and Africa, and the in-browser editor lets you review and correct any regional vocabulary while listening to the synced audio.
Does French transcription handle accents from African countries?
Sonix accepts French recordings from any region, including Francophone Africa. Because the transcript is stitched to the audio, you can quickly verify passages with regional pronunciation or code-switching and fix them in the editor.
Can I export French subtitles from my transcript?
Yes. After transcribing a French audio or video file, you can export the transcript as SRT or VTT subtitle files, as a Word document, or in dozens of other formats.
