Understanding English MK3D files
English spans many regional varieties, including American, British, Australian, Irish, Canadian, Caribbean, Indian, and Nigerian English, each with distinct pronunciation, vocabulary, and rhythm. Non-rhotic accents (many British and Australian varieties drop the "r" after vowels, as in "car" or "letter") and vowel shifts across regions are the variations most likely to affect speech recognition.

Frequently asked questions
How to improve the accuracy of your English transcripts?
Start by improving the quality of the English MK3D 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 English MK3D file that I upload?
Yes, please do not over-compress or over-filter the audio track of your English MK3D file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from MK3D, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in English with Sonix:
Does the 3D video affect transcription of an MK3D file?
No. Transcription uses only the audio track, so the stereoscopic layout stored in the StereoMode field has no effect on the resulting text.
Why won't my MK3D file play on my computer?
Many default media players do not recognize the .mk3d extension or lack stereoscopic support. Players that handle Matroska files, such as VLC, can usually open them, though the video may display as 2D without 3D-capable hardware.
Can Sonix transcribe British and Australian English as well as American English?
Yes. Sonix transcribes English recordings from any region, including British, Australian, Irish, Canadian, and Caribbean accents. Upload your file, review the transcript in the in-browser editor, and export it in your preferred format.
Does English transcription handle recordings with multiple accents?
Yes. A single English recording can include speakers with different regional accents, and Sonix transcribes them in one pass. Speaker labels help you attribute lines to each participant while you edit.
Can Sonix transcribe English audio with heavy background noise?
Sonix can transcribe noisy English audio, but cleaner recordings produce better results. Recordings with background noise, low volume, or crosstalk typically need more correction in the editor.
Trusted by professionals worldwide
The level of accuracy and your UI is quite amazing. It allowed me to try the product without having to learn anything new, I was so happy about it I sent the results to a couple of friends because I knew at the moment that this could change the way I work.
Sonix saves me 60% of the time editing. No more manual trascription nightmare with writing down timecodes, and sending emails. I think you are changing the game here! Bravo :)
