Recently I started getting time-out errors from the Bing Speech API for WinRT with any utterance audio that is longer than a few seconds. I'm having a hard time finding
a good technical contact for that group. Can you direct me to someone that could help? It's really ruining the speech recognition experience in my Windows Store App, and this is the app that won the Accela Grand Prize in their recent contest, so
I'm very eager to make this work. If the utterance is short, it works reliably, but anything longer than a few seconds and the Bing Speech recognizer times out. It never did this before. Here's the call I to the Bing Speech API control that
triggers the intermittent error:
// Start speech recognition.
var result = await _speechRecognizer.RecognizeSpeechToTextAsync();
Sometimes I get the following series of Exceptions during a failed session. Here's the thread state at the time of the failure, the current thread is the one currently executing the SetThinkingStateTimer() method:
