Understanding Bulgarian MP3 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 MP3 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 MP3 file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Bulgarian MP3 file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from MP3, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Bulgarian with Sonix:
Does the MP3 bitrate affect transcription quality?
It can. Files encoded at 128 kbps or higher preserve more speech detail, while heavily compressed recordings below about 96 kbps may introduce artifacts that make words harder to recognize.
How do I turn an MP3 recording into SRT subtitles?
Upload the MP3, generate a transcript, adjust the text and timings as needed, and export the result in SRT or VTT caption format.
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.
