We have received some requests about supporting text to speech in actions. We post it here to see whether others also find it useful.

To be able to trigger events such as text to speech based on the POI entering the field of view will allow for example a person who has bad eyesight to hear what their mobile is looking at.
Also a person who doesn't want to always look at their mobile, like when on a bike or driving or walking in the street… it will allow the user to get AR information from the layar browser in a more passive manner. Rather than always needing to look directly at their screen. This way they can just point it an listen.
