SpeechSynthesizer.SelectVoice() Fails with “No matching voice is installed or the voice was disabled”

问题

I am modifying Scott Hanselman's BabySmash code to support other languages.

I installed the speech platform and a new language per these steps.
The language now shows up in the registry:
The language can now be selected and played by Windows:
System.Speech.Synthesis.SpeechSynthesizer.GetInstalledVoices() now returns the voice.
However SelectVoice() in the code below throws the error "System.ArgumentException: Cannot set voice. No matching voice is installed or the voice was disabled."

string phrase = null;
SpeechSynthesizer speech = new SpeechSynthesizer();
CultureInfo keyboardCulture = System.Windows.Forms.InputLanguage.CurrentInputLanguage.Culture;
InstalledVoice neededVoice = speech.GetInstalledVoices(keyboardCulture).FirstOrDefault();
if (neededVoice == null)
{
    phrase = "Unsupported Language";
}
else if (!neededVoice.Enabled)
{
    phrase = "Voice Disabled";
}
else
{
    speech.SelectVoice(neededVoice.VoiceInfo.Name);
}

speech.Speak(phrase);

I've tried upgrading to C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.6.1\System.Speech.dll.
I've verified that the versions of Microsoft.Speech.dll and the language pack match.
This code works for the default voices I've already had installed.
In desperation, I've even tried invoking System.Speech.Internal.Synthesis.VoiceSynthesis.GetVoice() directly through reflection, but same exact error.

I would greatly appreciate any help you can provide! Thanks.

ha ha I feel special: this post on Python actually solved my problem: build configuration platform needs to be x64, not Any CPU!

Another solution is to install (x64) bits version of Microsoft Speech Platform SDK and Microsoft Server Speech Platform Runtime. I think that you had installed (x86) bits of both and the plataform try to read it in (x64) bits.

I had the same problem that you but on the contrary and this works to me!

In my case Instead of the library System.Speech.Synthesis i need to use Microsoft.Speech.Synthesis. For that we need to go to Solution Explorer on VisualStudio --> References and Browse for Microsoft.Speech.dll

using Microsoft.Speech.Synthesis;

After that you will have other Runtime Languages available.

        SpeechSynthesizer synth = new SpeechSynthesizer();    

        // Output information about all of the installed voices. 
        foreach (InstalledVoice voice in synth.GetInstalledVoices())
        {
            VoiceInfo info = voice.VoiceInfo;

            Console.WriteLine(" Name:          " + info.Name);
            Console.WriteLine(" Culture:       " + info.Culture);
            Console.WriteLine(" Age:           " + info.Age);
            Console.WriteLine(" Gender:        " + info.Gender);
            Console.WriteLine(" Description:   " + info.Description);
            Console.WriteLine(" ID:            " + info.Id);
        }
