範例

以下範例使用 Choices 和 GrammarBuilder 物件來創造一個可用來辨識語音輸入的片語，例如「Call Anne on her cell with her cell」和「Call James」 on his work phone。 範例使用從 Choices 和 String 隱式鑄造到 GrammarBuilder。

public Grammar CreatePhonePhrase()
{

  // Create alternatives for female names and add a phrase.
  GrammarBuilder females = new Choices(new string[] { "Anne", "Mary" });
  females.Append("on her");

  // Create alternatives for male names and add a phrase.
  GrammarBuilder males = new Choices(new string[] { "James", "Sam" });
  males.Append("on his");

  // Create a Choices object that contains an array of alternative
  // GrammarBuilder objects.
  Choices people = new Choices();
  people.Add(new Choices(new GrammarBuilder[] {females, males}));

  // Create a Choices object that contains a set of alternative phone types.
  Choices phoneType = new Choices();
  phoneType.Add(new string[] { "cell", "home", "work" });

  // Construct the phrase.
  GrammarBuilder gb = new GrammarBuilder();
  gb.Append("call");
  gb.Append(people);
  gb.Append(phoneType);
  gb.Append(new GrammarBuilder("phone"), 0, 1);

  return new Grammar(gb);
}

備註

此建構子回傳一組有效且空的替代方案。 你可以用任何 Add 方法加入替代方案。

範例

以下範例使用 Choices 和 GrammarBuilder 物件來建立 Grammar 像「Call Anne on her cell cell」和「Call James on his work phone」這類片語的 for。 範例使用從 Choices 和 String 隱式鑄造到 GrammarBuilder。

public Grammar CreatePhonePhrase()
{

  // Create alternatives for female names and add a phrase.
  GrammarBuilder females = new Choices(new string[] { "Anne", "Mary" });
  females.Append("on her");

  // Create alternatives for male names and add a phrase.
  GrammarBuilder males = new Choices(new string[] { "James", "Sam" });
  males.Append("on his");

  // Create a Choices object that contains an array of alternative
  // GrammarBuilder objects.
  Choices people = new Choices();
  people.Add(new Choices(new GrammarBuilder[] {females, males}));

  // Create a Choices object that contains a set of alternative phone types.
  Choices phoneType = new Choices();
  phoneType.Add(new string[] { "cell", "home", "work" });

  // Construct the phrase.
  GrammarBuilder gb = new GrammarBuilder();
  gb.Append("call");
  gb.Append(people);
  gb.Append(phoneType);
  gb.Append(new GrammarBuilder("phone"), 0, 1);

  return new Grammar(gb);
}

備註

每個 GrammarBuilder in alternateChoices 都定義了一個替代方案。 若 alternateChoices 為空陣列，建構子回傳一組空的備選方案。 你可以用任何 Add 方法加入替代方案。

當 是 或 ArgumentNullException 當任一陣列元素為 alternateChoices時，建構子會拋出一個 null 。null

由於該 GrammarBuilder 類別透過正確使用 cast 隱含地將 Choices、 SemanticResultValue及 SemanticResultKey 物件轉換為 GrammarBuilder 實例，此建構子也可用來從任意組合這些物件的清單中建立 Choices 物件。

範例

以下範例使用 Choices 和 GrammarBuilder 物件來創造像「Call Anne on her cell cell」和「Call James on his work phone」這類片語的 a Grammar 。 範例使用從 Choices 和 String 隱式鑄造到 GrammarBuilder。

public Grammar CreatePhonePhrase()
{

  // Create alternatives for female names and add a phrase.
  GrammarBuilder females = new Choices(new string[] { "Anne", "Mary" });
  females.Append("on her");

  return new Grammar(gb);
}

備註

每個 String in phrases 都定義了一個替代方案。 語音辨識引擎可以使用字串陣列中的任一個項目來匹配語音輸入。 若 phrases 為空陣列，建構子回傳一組空的備選方案。 你可以用任何 Add 方法加入替代方案。

當 ArgumentNullException 是 或phrases任一陣列元素 時null，建構子會拋null出 。 若陣列中有空字串（“”），則建構子會拋出 。ArgumentException
