  • Hi TIKSN,

    Based on your description, it seems that you want to know the difference of the TTS APIs among the Windows Desktop and Windows Store/Phone app. If so in Windows Desktop it uses this System.Speech.Synthesis APIs to implement the text-to-speech function. But in Windows Phone Runtime and Windows Store 8.1, it uses the Windows.Media.SpeechSynthesis APIs to implement the text-to-speech function.

    For the difference between the "Windows.Media.SpeechSynthesis" and "System.Speech.Synthesis", please try to check the reply which posted by @Rob Caplan - MSFT in here:

    If I have misunderstood you, please feel free to let me know.

    Best Regards,
