Understanding English MPGA 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 MPGA 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 MPGA file that I upload?
Yes, please do not over-compress or over-filter the audio track of your English MPGA file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from MPGA, 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 MPGA file open in my media player?
Some players do not recognize the .mpga extension even though the audio inside is standard MPEG audio. Renaming the file with an .mp3 extension usually lets any MP3-capable player open it.
Is an MPGA file the same as an MP3?
In most cases the audio data is identical, since both typically use MPEG-1 Audio Layer III encoding. The .mpga extension simply appears more often on audio tracks extracted from MPEG video files.
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.
