Understanding English AIFF 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 AIFF 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 AIFF file that I upload?
Yes, please do not over-compress or over-filter the audio track of your English AIFF file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from AIFF, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in English with Sonix:
Why are my AIFF files so large?
AIFF stores uncompressed PCM audio, which works out to roughly 10 MB per minute at CD quality. Converting to a compressed format like MP3 or a lossless codec like FLAC reduces the size if storage or upload time is a concern.
Do AIFF files play on Windows?
Most modern Windows media players and audio editors can open AIFF files, although WAV is the more common uncompressed format on that platform. If a specific program rejects the file, converting it to WAV preserves the audio exactly.
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.
