调研方向

Reproduce the issue with two UtteranceQueues sharing one Announcer, keeping the first queue nonempty. Start by tracing how UtteranceQueues are stepped through the stepTimer listener order and how readyToSpeak is consumed; done means both queues can announce rather than the later queue being blocked indefinitely.

描述

type:bug

If you share an Announcer between two UtteranceQueues and an UtteranceQueue doesn't empty it is is possible that the second UtteranceQueue will never get to announce because the Announcer is used up (never readyToSpeak ) by the first UtteranceQueue.

UtteranceQueues are stepped, and the order that they are stepped is determined by stepTimer listener order (i.e. order of UtteranceQueue creation). If the first UtteranceQueue in listener order always has Utterances, the second one may never speak.
