Gets or sets the volume (loudness) of the synthesized speech in the SpeechSynthesizer's audio output.
Namespace:
Microsoft.Speech.Synthesis
Assembly:
Microsoft.Speech (in Microsoft.Speech.dll)
Syntax
| Visual Basic (Declaration) |
|---|
Public Property TtsVolume As Integer Get Set |
| Visual Basic (Usage) |
|---|
Dim instance As SpeechSynthesizer Dim value As Integer value = instance.TtsVolume instance.TtsVolume = value |
| C# |
|---|
public int TtsVolume { get; set; } |
Property Value
Type: System..::..Int32Returns the volume of the synthesized voice in the SpeechSynthesizer's audio output, from 0 through 100.
Remarks
You can use this property to balance the level of the TTS voice with the level of recorded audio in a prompt. By contrast, the Volume property sets the level of the combined audio output for both the synthesized voice and audio files in a prompt.
Examples
The following example sets the level of the TTS voice to be compatible with the level of the WAV file ContosoWeather.wav.

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.
synth.SetOutputToDefaultAudioDevice();
// Set the volume of the TTS voice.
synth.TtsVolume = 50;
// Build a prompt containing recorded audio and synthesized speech.
PromptBuilder builder = new PromptBuilder(
new System.Globalization.CultureInfo("en-US"));
builder.AppendAudio("C:\\Test\\WelcomeToContosoRadio.wav");
builder.AppendText(
"The weather forecast for today is partly cloudy with some sun breaks.");
// Speak the prompt.
synth.Speak(builder);
}
Console.WriteLine();
Console.WriteLine("Press any key to exit...");
Console.ReadKey();
