Unfortunately, no. We are looking for the “Speech Synthesis” capability. The Sonos device type only registers with the following capabilities:
capability "Actuator" capability "Switch" capability "Refresh" capability "Sensor" capability "Music Player"
The “Speech Synthesis” capability could easily be added to the Sonos though… It already supports the actually functionality, just not the exact same interface.
@April - Who could we talk to to get this added to the default Sonos device type?
