SpObjectToken MatchesAttributes Method (SAPI 5.3)

Speech API 5.3
Microsoft Speech API 5.3

Object: SpObjectToken

MatchesAttributes Method

The MatchesAttributes method indicates whether the token matches specified attributes.


SpObjectToken.MatchesAttributes(
     Attributes As String
) As Boolean

Parameters

Attributes
Specifies the Attributes.

Return Value

A Boolean variable. If True, the token matches the specified attributes; if False, it does not match.


Example

The following Visual Basic form code demonstrates the use of the MatchesAttibutes method. To run this code, create a form with the following controls:

  • A combo box control called Combo1
  • A command button called Command1
  • A list box called List1

Paste this code into the Declarations section of the form.

The Form_Load procedure initializes a new SpObjectTokenCategory object to the voices category, selects all voices into an ISpeechObjectTokens collection, and loads Combo1 with several attribute declarations. These attributes are intentionally irregular with regard to capitalization, spacing, and spelling.

The Command1 procedure contains a loop that performs a MatchesAttibutes call on each available voice. The name of each voice and the Boolean result of the MatchesAttibutes method is displayed in the list box.
