Understanding Bulgarian FLV 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 FLV 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 FLV file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Bulgarian FLV file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from FLV, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Bulgarian with Sonix:
Why won't my FLV file play on my computer?
FLV was designed for Adobe Flash Player, which was discontinued at the end of 2020, so modern browsers and many media players no longer support it. Players such as VLC can still open FLV files, or you can convert them to MP4 for broader compatibility.
Do I need to convert FLV to MP4 before transcribing?
No, FLV files can be uploaded directly for transcription. Converting to MP4 is only needed if you also want the video to play in modern browsers or editing software.
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.
