@dankaj -- Could you please look into the issue, pardon me if it has nothing to do with your changes and if possible please assign it to the concern Dev.
Thank You.

Um, the CL only renames methods, and wasn't in the regression range, I'm missing why this assigned to me.

Unable to find the exact culprit from the CL. Could some one please look into the issue and update.
Thank You.

Have the mock PlatformSpeechSynthesizer ignore pause/resume sometimes.

Should pause()/resume() be attempted without nothing being currently
spoken, just ignore.
