Exempel

Kodexemplet nedan är en del av ett konsolprogram som visar emulerade indata, associerade igenkänningsresultat och associerade händelser som genereras av taligenkänningen. Exemplet genererar följande utdata.

TestRecognize("Smith")...
 SpeechDetected event raised.
 SpeechRecognized event raised.
  Grammar = Smith; Text = Smith
...Recognition result text = Smith

TestRecognize("Jones")...
 SpeechDetected event raised.
 SpeechRecognized event raised.
  Grammar = Jones; Text = Jones
...Recognition result text = Jones

TestRecognize("Mister")...
 SpeechDetected event raised.
 SpeechHypothesized event raised.
  Grammar = Smith; Text = mister
 SpeechRecognitionRejected event raised.
  Grammar = <not available>; Text =
...No recognition result.

TestRecognize("Mister Smith")...
 SpeechDetected event raised.
 SpeechRecognized event raised.
  Grammar = Smith; Text = mister Smith
...Recognition result text = mister Smith

Kommentarer

Taligenkänningen genererar SpeechDetectedhändelserna , SpeechHypothesized, SpeechRecognitionRejectedoch SpeechRecognized som om igenkänningsåtgärden inte emuleras.

De identifierare som levereras med Vista och Windows 7 ignorera skiftläge och teckenbredd när grammatikregler tillämpas på indatafrasen. Mer information om den här typen av jämförelse finns i CompareOptions uppräkningsvärdena OrdinalIgnoreCase och IgnoreWidth. Igenkännarna ignorerar också nya linjer och extra tomt utrymme och behandlar skiljetecken som literalindata.

Identifieraren använder compareOptions när den tillämpar grammatikregler på indatafrasen. De identifierare som levereras med Vista och Windows 7 ignorera fall om värdet OrdinalIgnoreCase eller IgnoreCase finns. Identifieraren ignorerar alltid teckenbredden och ignorerar aldrig Kana-typen. Identifieraren ignorerar också nya linjer och extra tomt utrymme och behandlar skiljetecken som literalindata. Mer information om teckenbredd och Kana-typ finns i CompareOptions uppräkningen.
