Understanding Bulgarian AAC files
Bulgarian splits into Eastern and Western dialect groups along the yat vowel line, which changes how certain vowels are pronounced across the country. Standard Bulgarian, the norm in broadcasting and formal speech, draws mainly on northeastern dialects, so recordings of standard speech are the most predictable input for speech recognition.

Frequently asked questions
How to improve the accuracy of your Bulgarian transcripts?
Start by improving the quality of the Bulgarian AAC 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 Bulgarian AAC file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Bulgarian AAC file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from AAC, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Bulgarian with Sonix:
What is the difference between AAC and M4A files?
Both typically contain the same AAC-encoded audio; the difference is packaging. A .aac file is a raw ADTS stream, while a .m4a file wraps the audio in an MPEG-4 container that supports metadata such as tags, artwork, and chapters.
Why won't my AAC file open in some apps?
Raw .aac files are a bare audio stream without a standard container, so some players and editors that expect MP4/M4A files cannot read them. Renaming the extension does not fix this — remux or convert the file into an M4A or MP3 instead.
Can Sonix transcribe Bulgarian audio and video?
Yes. Upload your Bulgarian audio or video file, Sonix generates a transcript automatically, and you can review and edit it in the browser before exporting to formats like DOCX, PDF, or SRT.
Does Bulgarian transcription output Cyrillic text?
Yes. Bulgarian is written in the Cyrillic alphabet, and transcripts are produced in Cyrillic, matching how the language is normally written.
Does Sonix handle regional Bulgarian dialects?
Recognition is based on standard Bulgarian, so clear standard speech works best. Recordings with strong eastern or western dialect features can still be transcribed, but expect to spend more time reviewing them in the editor.
