Windows 10 - System.Speech.Synthesis cannot get Mo

Question

In my Windows 10's Language, I have installed 2 version of English Language:

• US
• United Kingdom

Therefore, in [Settings] > [Time & language] > [Speech]

Under the section [Text-to-Speech], I can see the following options:

• Microsoft David Mobile
• Microsoft George Mobile
• Microsoft Susan Mobile
• Microsoft Hazel Mobile
• Microsoft Zira Mobile
• Microsoft Mark Mobile

but, in C# WinForm, by using the following code:

using System.Speech.Synthesis;
SpeechSynthesizer ss = new SpeechSynthesizer();
ss.GetInstalledVoices();

I can only get:

• Microsoft David Desktop
• Microsoft Hazel Desktop
• Microsoft Zira Desktop

I missed Susan, George and Mark.

How can I get Susan, George and Mark voice version in C# WinForm?

Answer 1

You can only access the Windows 10 Voices from the Windows.Media.SpeechSynthesis Namespace which belongs to the WinRT Framework. So you cant use them in WPF or WinForms.
