I would like to reopen this discussion regarding routing of speech output. It would be VERY useful if synthesized speech could be dynamically routed to one or the other headphone speaker by an app. This would allow an app to send speech from 2 different voice profiles to 2 different audio channels. Perhaps even doing the reverse and suppressing output for the opposite channel might afford a cheap n easy way to route the audio to a single L/R channel.
Has any development of this been done since the preceding 2012 posting?
