Understanding Swahili OGA 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 OGA 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 OGA file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Swahili OGA file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from OGA, 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 OGA file play on my iPhone or in Apple Music?
Apple's built-in media apps do not include Ogg Vorbis decoders, so OGA files require a third-party player such as VLC or conversion to a supported format like M4A or MP3.
Do I need to convert OGA to MP3 before transcribing it?
No. OGA files can be uploaded directly for transcription; conversion is only needed if you want to play the file in software without Ogg support.
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.
