PromptBuilder.StartStyle Method

Specifies the start of a style in the PromptBuilder object.

Namespace:  Microsoft.Speech.Synthesis
Assembly:  Microsoft.Speech (in Microsoft.Speech.dll)

public void StartStyle(
	PromptStyle style


Type: Microsoft.Speech.Synthesis.PromptStyle
The style to start.

The StartStyle(PromptStyle) method takes a PromptStyle object as its argument. You can use the properties of the PromptStyle object to set the emphasis, speaking rate, and volume (loudness) to apply to speech output while the style is in effect. To stop using the current style, call the EndStyle() method.

The following example creates a PromptBuilder object and appends text strings. The example uses the StartStyle(PromptStyle) method to specify a slow speaking rate for the string being added, which enumerates the contents of an order.

using System;
using Microsoft.Speech.Synthesis;

namespace SampleSynthesis
  class Program
    static void Main(string[] args)

      // Initialize a new instance of the SpeechSynthesizer.
      using (SpeechSynthesizer synth = new SpeechSynthesizer())

        // Configure the audio output. 

        // Create a SoundPlayer instance to play the output audio file.
        System.Media.SoundPlayer m_SoundPlayer =
          new System.Media.SoundPlayer(@"C:\test\Style.wav");

        // Create a PromptBuilder object and add content.
        PromptBuilder style = new PromptBuilder();
        style.AppendText("Your order for");
        style.StartStyle(new PromptStyle(PromptRate.Slow));
        style.AppendText("one kitchen sink and one faucet");
        style.AppendText("has been confirmed.");

        // Speak the prompt and play back the output file.

      Console.WriteLine("Press any key to exit...");
