Understanding Swahili OPUS files
Standard Swahili is based on Kiunguja, the dialect of Zanzibar, and is the variety most speech recognition models target. Congolese Swahili (Kingwana) in the DRC and urban varieties such as Kenya's Sheng, which mixes Swahili with English, can differ noticeably from broadcast-standard Swahili.

Frequently asked questions
How to improve the accuracy of your Swahili transcripts?
Start by improving the quality of the Swahili 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 Swahili OPUS file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Swahili 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 Swahili 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 Congolese Swahili?
You can upload recordings in Congolese Swahili (Kingwana) and select Swahili as the spoken language. Because Kingwana differs from the East African standard, plan to review and polish the transcript in the browser editor before exporting.
Does Swahili transcription handle audio mixed with English?
Swahili recordings from Kenya and urban East Africa often include English words and phrases. Sonix transcribes the file with the Swahili model you select, and the synced editor makes it straightforward to correct code-switched passages.
What formats can I export a Swahili transcript to?
After transcribing, you can edit the transcript in your browser and export it to formats including Word, PDF, plain text, and SRT or VTT subtitle files.
