Frequently asked questions
How to improve the accuracy of your Esperanto transcripts?
Start by improving the quality of the Esperanto M4A 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 M4A file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Esperanto M4A file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from M4A, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Esperanto with Sonix:
How do I transcribe an iPhone voice memo saved as M4A?
Export or share the recording from the Voice Memos app, then upload the M4A file directly. Once the automatic transcript is ready, you can edit it and export the text in your preferred format.
Is an M4A file the same as an AAC file?
Not exactly. AAC is the audio codec, while M4A is the MPEG-4 container that usually holds AAC data (and sometimes Apple Lossless). In practice, most M4A files play anywhere AAC is supported.
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.
