Understanding Esperanto FLV files
Esperanto is a constructed language with a single standardized form and no regional dialects. In practice, pronunciation varies with each speaker's native language, so recordings from international gatherings can mix many different accents in one conversation.

Frequently asked questions
How to improve the accuracy of your Esperanto transcripts?
Start by improving the quality of the Esperanto 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 Esperanto FLV file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Esperanto 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 Esperanto 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 Esperanto audio and video?
Yes. Upload your recording, select Esperanto as the spoken language, and Sonix generates a transcript you can edit alongside the original audio and export as documents or subtitles.
Does Esperanto transcription handle different accents?
Esperanto speakers carry accents from their native languages, so pronunciation varies from speaker to speaker. Sonix's browser editor syncs the transcript to the audio, making it easy to review and correct accent-related mistakes.
Will Esperanto's special characters like ĉ and ŭ appear in my transcript?
Yes. Transcripts and exports use standard Unicode text, so the six diacritic letters (ĉ, ĝ, ĥ, ĵ, ŝ, ŭ) are preserved in documents and subtitle files.
