feed 7 means Text to Speech
Synthesized speech, such as audiobooks or a site plugin that reads articles aloud (MISC class). Not in OpenRTB 2.5.
When to send it
Send 7 when the audio is produced by text to speech: a website plugin that reads articles aloud, or audiobooks voiced by software. AdCOM classes it as miscellaneous.
Buyers use 7 to separate synthetic narration of written content from produced audio, which affects brand-safety review, because the audio says whatever the text says. It is confused with 3 when a publisher distributes its read-aloud articles as a podcast feed; the feed type should describe how the audio was made.
