Understanding Esperanto AAC 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 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 Esperanto AAC file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Esperanto 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 Esperanto 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 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.
