It would be very helpful to be able to get a stream of the output of SpeechSynthesis.

For an explicit use cases, I would like to:

• position speech synthesis in a virtual world in WebXR (using Web Audio's PannerNode)
• be able to feed speech synthesis output through a WebRTC connection
• have speech synthesis output be able to be processed through Web Audio

(This is similar/inverse/matching/related feature to #66.)
