I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

apparently here?

runtime/src/libraries/System.Speech/tests/SynthesizeRecognizeTests.cs

Line 52 in dd6696a

Assert.True(result.Confidence > 0.1);

looks like this means the timeout expired for recognition - for some reason.

options

1. register for SpeechRecognitionRejected event, triggered by check here. question is -- does that count as a pass? if it does, how do we know recognition ever works
   

   runtime/src/libraries/System.Speech/src/Recognition/RecognizerBase.cs

   Line 2355 in dd6696a

   FireSpeechRecognitionRejectedEvent(result);

2. increase the timeout. default is 30 secs. looks like InitialSilenceTimeout allows that (despite the name)
   

   runtime/src/libraries/System.Speech/src/Recognition/RecognizerBase.cs

   Line 596 in dd6696a

   TimeSpan eventTimeout = TimeSpan.FromTicks(Math.Max(initialSilenceTimeout.Ticks, _defaultTimeout.Ticks));

Seems like 2 is reasonable to start.

[danmoseley]

BTW, this test is kind of the "key" test that verifies recognition works so I would recommend not disabling it as a first approach.

@jeffhandley apparently the bot json didn't get picked up yet as I got tagged 😸

We've not made the change yet. Thanks for tagging me.

I'm looking at improving the test.
