Understanding English WEBM 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 WEBM 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 WEBM file that I upload?
Yes, please do not over-compress or over-filter the audio track of your English WEBM file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from WEBM, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in English with Sonix:
Why won't my WebM file open in my video editor?
Many desktop editing applications do not include VP8/VP9 decoders, so WebM files may need conversion to MP4 before importing, even though browsers and players like VLC handle them natively.
How do I get subtitles from a WebM video?
Upload the WebM file for transcription, review and edit the resulting transcript, then export it as an SRT or VTT caption file that most video players and platforms accept.
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.

I’ve been using your transcription software for about a year now. I just wanted to let you guys know that I think it is incredible. I have tried many alternatives, and none of them have been able to match the accuracy of Sonix!
I LOVE Sonix. It's saving my life. I'm working on a project with almost NO budget, interviewing a bunch of people and the Sonix transcriptions are accurate, and are so easy and intuitive to correct.
