 void Append(System::String ^ phrase, int minRepeat, int maxRepeat);

public void Append (string phrase, int minRepeat, int maxRepeat);

member this.Append : string * int * int -> unit

Public Sub Append (phrase As String, minRepeat As Integer, maxRepeat As Integer)

Parâmetros

Exemplos

O exemplo a seguir cria uma gramática de reconhecimento de fala para frases como "Chamar James no trabalho" e "Chamar Anne em seu celular", em que a palavra "telefone" é opcional. GrammarBuilder e Choices objetos são usados para construir a gramática. O exemplo realça o uso do Append método .

public static Grammar CreatePhonePhrase()
{
  // Create alternatives for person names, locations, devices, and pronouns.
  Choices personChoice = new Choices(new string[] {"Anne", "James", "Mary", "Sam"});
  Choices locationChoice = new Choices(new string[] {"home", "work"});
  Choices deviceChoice = new Choices(new string[] {"home", "work", "cell"});
  Choices pronounChoice = new Choices(new string[] {"his", "her"});

  // Create a phrase for the receiving device, which optionally contains the word "phone".
  GrammarBuilder devicePhrase = new GrammarBuilder(pronounChoice);
  devicePhrase.Append(deviceChoice);
  devicePhrase.Append("phone", 0, 1);

  // Create alternatives for phrases specifying a device or a location.
  GrammarBuilder atLocation = new GrammarBuilder("at");
  atLocation.Append(locationChoice);

  GrammarBuilder onDevice = new GrammarBuilder("on");
  onDevice.Append(devicePhrase);

  Choices howChoice = new Choices(new GrammarBuilder[] {atLocation, onDevice});

  // Build the final phrase.
  GrammarBuilder callWho = new GrammarBuilder("Call");
  callWho.Append(personChoice);
  callWho.Append(howChoice);

  // Create the Grammar object.
  Grammar callGrammar = new Grammar(callWho);
  callGrammar.Name = "Call Grammar";

  return callGrammar;
}

Comentários

O valor de minRepeat deve ser maior ou igual a 0 e menor ou igual ao valor de maxRepeat.

Parâmetros

Exemplos

O exemplo a seguir cria uma gramática de reconhecimento de fala para cada SubsetMatchingMode valor. Por exemplo, a gramática OrderedSubset gerada reconhece as frases , "três quatro cinco" e "um três cinco", e a gramática Subsequence reconhece a frase "três quatro cinco", mas não a frase , "um três cinco".

private Grammar[] CreateSubsetMatchTest()
{
  List<Grammar> grammars = new List<Grammar>(4);

  string phrase = "one two three four five six";
  foreach (SubsetMatchingMode mode in
    Enum.GetValues(typeof(SubsetMatchingMode)))

    GrammarBuilder gb = new GrammarBuilder();
    gb.Append(phrase, mode);

    Grammar grammar = new Grammar(gb);

O elemento subconjunto é adicionado ao final da sequência atual de elementos. Para obter mais informações sobre como criar uma gramática de reconhecimento de fala usando cadeias de caracteres, consulte Usando cadeias de caracteres para criar uma gramática GrammarBuilder.
