Understanding Swahili CAF 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 CAF 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 CAF file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Swahili CAF file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from CAF, 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 CAF file play on Windows?
CAF is an Apple container that most Windows applications do not support natively. You can open it with a third-party player such as VLC, or convert it to WAV or MP3 for broader compatibility.
How large can a CAF file be?
CAF uses 64-bit file offsets, so there is no practical size limit and recordings can run for many hours. This is the main advantage over WAV and AIFF, which are capped at 4 GB.
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.
Trusted by professionals worldwide
It really accelerated my work and I was amazed by the accuracy, especially given that the video featured only non-native speakers.
Seriously the best transcript I’ve ever seen. And the synchronized editor is amazing. I will be using again and I will be sharing with my friends :)
