Understanding Swahili RM 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 RM 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 RM file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Swahili RM file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from RM, 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 RM file play on my computer?
RM is a proprietary RealNetworks format that modern operating systems no longer support out of the box. You typically need RealPlayer, or a player like VLC that offers partial RM support.
Should I convert my RM files to a modern format?
For long-term preservation, converting to a widely supported format like MP4 is a reasonable step, since RM playback support continues to shrink. Keep the original file as well, because re-encoding a lossy format can reduce quality slightly.
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.

The entire process is extremely straightforward and what I liked most was the accuracy of the transcriptions and translations. I must say, I had some doubts as to what the quality would be like since it was in French, but I was not disappointed in the least.
The highest accuracy I have ever achieved through similar services.
