5	speak(utterance2)	FALSE	TRUE	FALSE	utterance1		FALSE	TRUE	FALSE	W1 calls speak() again before the first utterance ends.
6		FALSE	TRUE	TRUE		speak(utterance3)	FALSE	TRUE	FALSE	W2 calls speak() while Window 1 is speaking.
7		FALSE	TRUE	TRUE			FALSE	TRUE	TRUE
8		FALSE	TRUE	TRUE	utterance3		FALSE	TRUE	FALSE	W2 gets output next, even though W1 called speak first.
9		FALSE	TRUE	TRUE	utterance3		FALSE	TRUE	FALSE
10		FALSE	TRUE	FALSE	utterance2		FALSE	TRUE	FALSE
11		FALSE	TRUE	FALSE			FALSE	TRUE	FALSE
12		FALSE	TRUE	FALSE			FALSE	TRUE	FALSE

14	Case 2. Pause while speaking
15		FALSE	FALSE	FALSE		speak(utterance4)	FALSE	FALSE	FALSE
16	pause()	TRUE	TRUE	FALSE	utterance4		FALSE	TRUE	FALSE	W1 can't pause utterance it didn't speak, but it's local state is paused
17	speak(utterance5)	TRUE	TRUE	FALSE			FALSE	TRUE	FALSE	W1 speaks in paused state, utterance is queued
18		TRUE	TRUE	TRUE		pause()	FALSE	TRUE	FALSE	W2 can pause its own utterance.
19		TRUE	TRUE	TRUE		resume()	TRUE	TRUE	FALSE	W2 can resume its own utterance
20		TRUE	TRUE	TRUE			FALSE	TRUE	FALSE
21	resume()	TRUE	FALSE	TRUE			FALSE	FALSE	FALSE	W1 is in paused state, needs to resume to get spoken
22		FALSE	TRUE	FALSE	utterance5		FALSE	TRUE	FALSE

27	speak(utterance7)	FALSE	TRUE	TRUE		speak(utterance9)	FALSE	TRUE	TRUE
28		FALSE	TRUE	TRUE		cancel()	FALSE	TRUE	TRUE	W2 can't stop utterance from other window, but its queue will be dropped.

36	speak(utterance10)	TRUE	FALSE	FALSE			FALSE	FALSE	FALSE	W1 speak method is held by local paused state
37		TRUE	FALSE	TRUE		speak(utterance11)	FALSE	FALSE	FALSE
38	resume()	TRUE	TRUE	TRUE	utterance11		FALSE	TRUE	FALSE	W1 calls resume, utterance gets queued
39		FALSE	TRUE	TRUE	utterance11		FALSE	TRUE	FALSE
