Understanding Esperanto OPUS 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 OPUS 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 OPUS file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Esperanto OPUS file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from OPUS, 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 OPUS file play on my computer?
Older media players and some built-in OS players lack Opus support. Opening the file in VLC or a modern web browser, or converting it to MP3 or WAV, usually resolves the issue.
Are WhatsApp voice messages OPUS files?
Yes, WhatsApp exports voice notes as .opus files. You can upload them for transcription directly without converting them first.
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.
