[mst-content-hint] Differentiate between speech for human and machine consumption (#39)

sjdallst has just created a new issue for https://github.com/w3c/mst-content-hint:

== Differentiate between speech for human and machine consumption ==
There are different requirements for speech that is meant to be listened to by a human, and speech that is to be transcribed by a machine (signal preservation vs listening experience). The current spec leans towards speech that is meant for human ears. It would be helpful for applications seeking to do speech recognition if there was a more specific contentHint for that purpose.
