Understanding Swahili AAC 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 AAC 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 AAC file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Swahili AAC file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from AAC, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Swahili with Sonix:
What is the difference between AAC and M4A files?
Both typically contain the same AAC-encoded audio; the difference is packaging. A .aac file is a raw ADTS stream, while a .m4a file wraps the audio in an MPEG-4 container that supports metadata such as tags, artwork, and chapters.
Why won't my AAC file open in some apps?
Raw .aac files are a bare audio stream without a standard container, so some players and editors that expect MP4/M4A files cannot read them. Renaming the extension does not fix this — remux or convert the file into an M4A or MP3 instead.
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.
