The current implementation of speech synthesis has a queue inside the SpeechSynthesis object that's owned by one DOMWindow. This isn't likely to work very well if multiple windows try to speak at the same time.

I think that the queue needs to be pushed into the WebKit layer so that a multi-process browser can implement a single speech queue.

I filed this bug against the speech API to clarify the exact semantics of what should happen if multiple windows try to speak, but I think that no matter how this is resolved, we'll want at least some global state.
