ContourPoint Structure
Represents changes in pitch for the speech content of a TextFragment.
Namespace: System.Speech.Synthesis.TtsEngine
Assembly: System.Speech (in System.Speech.dll)
The ContourPoint type exposes the following members.
| Name | Description | |
|---|---|---|
 | Change | Gets the value that represents the amount to raise or lower the pitch at a point in a TextFragment. |
| ChangeType | Gets a member of ChangeType that specifies the unit to use for the number specified in the change parameter of a ContourPoint object. |
| Start | Gets a Single that specifies the point at which to apply the pitch change in a TextFragment. This is expressed as the elapsed percentage of the duration of the TextFragment at that point. |
| Name | Description | |
|---|---|---|
| Equals(ContourPoint) | Determines if a given instance of ContourPoint is equal to the current instance of ContourPoint. |
| Equals(Object) | Determines if a given object is an instance of ContourPoint and equal to the current instance of ContourPoint. (Overrides ValueType.Equals(Object).) |
| GetHashCode | Returns a hash code for this instance. (Overrides ValueType.GetHashCode().) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| ToString | Returns the fully qualified type name of this instance. (Inherited from ValueType.) |
| Name | Description | |
|---|---|---|
| Equality | Determines if two instances of ContourPoint are equal. |
| Inequality | Determines if two instances of ContourPoint are NOT equal. |
The pitch contour is defined as an array of targets at specified time positions in the speech output. Each target is defined by three parameters. The first value is a percentage of the period of the contained text (a number followed by "%"). The second value specifies the amount to raise or lower the pitch. The third value designates the unit to use for the number specified in the second value; either percentage or hertz (Hz).
ContourPoint objects are obtained by the GetContourPoints method, or used to set the pitch contour for a TextFragment by the SetContourPoints method.
