EpubCCEPUBCheck OPF-095: voicing link not audio
Updated:
EPUBCheck OPF-095 is an error message: “The "media-type" attribute of "voicing" links must be an audio MIME type, but found "…".” A voicing link in the metadata declares a media type that is not audio. A voicing link points to a recording of a title or name being spoken, so its media type must be an audio type.
The official message
The "media-type" attribute of "voicing" links must be an audio MIME type, but found "%1$s".
- Default severity
- Error. The EPUB breaks a rule of the specification and is invalid. Stores and Send to Kindle may reject it, and EPUBCheck exits with status 1.
- EPUBCheck version
- 5.4.0
%1$s, %2$s… are filled in with the file, value or element EPUBCheck found.
Typical causes
- A media type typo, such as audio/mp3 written as application/mp3.
- A link to a non-audio file marked as voicing by mistake.
- A media type copied from another link.
How to fix it
- Find the link EPUBCheck points to and check the file it links to.
- Set media-type to the file's real audio type, for example audio/mpeg for MP3 or audio/mp4 for AAC.
- If the file is not audio, change rel or remove the link.
When it's not this
If the voicing link has no media type at all, that is OPF-094.
