SrgsOneOf Constructors

Definition

Namespace:

System.Speech.Recognition.SrgsGrammar

Assembly:

System.Speech.dll

Package:

System.Speech v9.0.0

Creates a new instance of the SrgsOneOf class.

Overloads

SrgsOneOf()	Initializes a new instance of the SrgsOneOf class.
SrgsOneOf(SrgsItem[])	Initializes a new instance of the SrgsOneOf class from an array of SrgsItem objects.
SrgsOneOf(String[])	Initializes a new instance of the SrgsOneOf class from an array of String objects.

Remarks

You can construct an instance of the SrgsOneOf class from an array of String objects, from an array of SrgsItem objects, or as an empty list. Using SrgsItem objects instead of String objects in a list of alternatives lets you apply properties of SrgsItem to each item in the list, such as MinRepeat, MaxRepeat, RepeatProbability, and Weight.

SrgsOneOf()

Source:

SrgsOneOf.cs

Initializes a new instance of the SrgsOneOf class.

public:
 SrgsOneOf();

public SrgsOneOf ();

Public Sub New ()

Examples

The following example uses the SrgsOneOf element to build lists of SrgsItem elements containing country/region names, any one of which may be used to recognize the containing phrase. The example then adds one of the resulting SrgsOneOf objects to their respective rules for European and South American countries/regions. Further on, the example uses the SrgsOneOf object to group rule references to ruleEurope and ruleSAmerica into a list of two alternatives, either one of which may be used to recognize spoken input.

public void WorldSoccerWinners ()
{

  // Create an SrgsDocument, create a new rule
  // and set its scope to public.
  SrgsDocument document = new SrgsDocument();
  SrgsRule winnerRule = new SrgsRule("WorldCupWinner");
  winnerRule.Scope = SrgsRuleScope.Public;

  // Add the introduction.
  winnerRule.Elements.Add(new SrgsItem("A nation that has won the world cup is: "));

  // Create the rule for the European nations.
  SrgsOneOf oneOfEurope = new SrgsOneOf(new SrgsItem[] {new SrgsItem("England"),
    new SrgsItem("France"), new SrgsItem("Germany"), new SrgsItem("Italy")});
  SrgsRule ruleEurope = (new SrgsRule("EuropeanNations", new SrgsElement[] {oneOfEurope}));

  // Create the rule for the South American nations.
  SrgsOneOf oneOfSAmerica = new SrgsOneOf(new SrgsItem[] {new SrgsItem("Argentina"),
    new SrgsItem("Brazil"), new SrgsItem("Uruguay")});
  SrgsRule ruleSAmerica = (new SrgsRule("SouthAmericanNations", new SrgsElement[] {oneOfSAmerica}));

  // Add references to winnerRule for ruleEurope and ruleSAmerica.
  winnerRule.Elements.Add(new SrgsOneOf(new SrgsItem[] {(new SrgsItem
    (new SrgsRuleRef(ruleEurope))), new SrgsItem(new SrgsRuleRef(ruleSAmerica))}));

  // Add all the rules to the document and make winnerRule
  // the root rule of the document.
  document.Rules.Add(new SrgsRule[] {winnerRule, ruleEurope, ruleSAmerica});
  document.Root = winnerRule;
}

SrgsOneOf(SrgsItem[])

Source:

SrgsOneOf.cs

Initializes a new instance of the SrgsOneOf class from an array of SrgsItem objects.

public:
 SrgsOneOf(... cli::array <System::Speech::Recognition::SrgsGrammar::SrgsItem ^> ^ items);

public SrgsOneOf (params System.Speech.Recognition.SrgsGrammar.SrgsItem[] items);

new System.Speech.Recognition.SrgsGrammar.SrgsOneOf : System.Speech.Recognition.SrgsGrammar.SrgsItem[] -> System.Speech.Recognition.SrgsGrammar.SrgsOneOf

Public Sub New (ParamArray items As SrgsItem())

Parameters

items

SrgsItem[]

The alternative items to add.

Exceptions

ArgumentNullException

items is null.

Any element in the items array is null.

Examples

The following example creates a grammar that recognizes the phrase "A nation that has won the World Cup is" followed by the name of a country/region that has won the World Cup. It creates a public rule named WorldCupWinner. It then creates two SrgsRule objects using SrgsOneOf objects that contain arrays of new SrgsItem objects. To see the grammar that this example generates, see SrgsRule.

 public void WorldSoccerWinners ()
{

  // Create an SrgsDocument, create a new rule
  // and set its scope to public.
  SrgsDocument document = new SrgsDocument();
  SrgsRule winnerRule = new SrgsRule("WorldCupWinner");
  winnerRule.Scope = SrgsRuleScope.Public;

  // Add the introduction.
  winnerRule.Elements.Add(new SrgsItem("A nation that has won the world cup is: "));

  // Create the rule for the European nations.
  SrgsOneOf oneOfEurope = new SrgsOneOf(new SrgsItem[] {new SrgsItem("England"), new SrgsItem("France"), new SrgsItem("Germany"), new SrgsItem("Italy")});
  SrgsRule ruleEurope = (new SrgsRule("EuropeanNations", new SrgsElement[] {oneOfEurope}));

  // Create the rule for the South American nations.
  SrgsOneOf oneOfSAmerica = new SrgsOneOf(new SrgsItem[] {new SrgsItem("Argentina"), new SrgsItem("Brazil"), new SrgsItem("Uruguay")});
  SrgsRule ruleSAmerica = (new SrgsRule("SouthAmericanNations", new SrgsElement[] {oneOfSAmerica}));

  // Add references to winnerRule for ruleEurope and ruleSAmerica.
  winnerRule.Elements.Add(new SrgsOneOf(new SrgsItem[] {(new SrgsItem
    (new SrgsRuleRef(ruleEurope))), new SrgsItem(new SrgsRuleRef(ruleSAmerica))}));

  // Add all the rules to the document and make winnerRule
  // the root rule of the document.
  document.Rules.Add(new SrgsRule[] {winnerRule, ruleEurope, ruleSAmerica});
  document.Root = winnerRule;
}

SrgsOneOf(String[])

Source:

SrgsOneOf.cs

Initializes a new instance of the SrgsOneOf class from an array of String objects.

public:
 SrgsOneOf(... cli::array <System::String ^> ^ items);

public SrgsOneOf (params string[] items);

new System.Speech.Recognition.SrgsGrammar.SrgsOneOf : string[] -> System.Speech.Recognition.SrgsGrammar.SrgsOneOf

Public Sub New (ParamArray items As String())

Parameters

items

String[]

The alternative items to add.

Exceptions

ArgumentNullException

items is null.

Any element in the items array is null.

Examples

The following example creates a grammar that recognizes the phrase "A nation that has won the World Cup is" followed by the name of a country/region that has won the World Cup. The example uses the SrgsOneOf element to build lists of acceptable country/region names from an array of String objects. The example then adds one of the resulting SrgsOneOf objects to their respective rules for European and South American countries/regions.

public void WorldSoccerWinners ()
{
    // Create a grammar from an SRGSDocument, create a new rule
  // and set its scope to public.
  SrgsDocument srgsGrammar = new SrgsDocument ();
  SrgsRule winnerRule = new SrgsRule ("WorldCupWinner");
  winnerRule.Scope = SrgsRuleScope.Public;

  // Add the introduction.
  winnerRule.Elements.Add (new SrgsItem ("A nation that has won the world cup is"));

  // Create the rule for the European nations.
  SrgsOneOf oneOfEurope = new SrgsOneOf (new string[] {"England","France","Germany","Italy"});
  SrgsRule ruleEurope = (new SrgsRule("EuropeanNations", new SrgsElement[] {oneOfEurope}));

  // Create the rule for the South American nations.
  SrgsOneOf oneOfSAmerica = new SrgsOneOf (new string[] {"Argentina","Brazil","Uruguay"});
  SrgsRule ruleSAmerica = (new SrgsRule("SouthAmericanNations", new SrgsElement[] {oneOfSAmerica}));

  // Add references to winnerRule for ruleEurope and ruleSAmerica.
  winnerRule.Elements.Add(new SrgsOneOf(new SrgsItem[] {(new SrgsItem
    (new SrgsRuleRef(ruleEurope))), new SrgsItem(new SrgsRuleRef(ruleSAmerica))}));

  // Add all the rules to the grammar and make winnerRule
  // the root rule of the grammar.
  srgsGrammar.Rules.Add (new SrgsRule[] {winnerRule, ruleEurope, ruleSAmerica});
  srgsGrammar.Root = winnerRule;
}
