问题:

Is Speech api available in WinRT (like Windows Phone 8).
Can I use some third party speech api instead?

I want to implement TTS in my Windows 8/WinRT application, does anyone have some suggestions?

回答1:

Speech is now available for WinRT

Voice Commands and Speech Recognition are available on phone only.

TTS is available for all winRT devices.

回答2:

There is no Speech API available in WinRT.

There may be 3rd party WinRT components, you would have to look for those. I am not aware of any, but I only did a cursory search.

If being connected to the internet as an app requirement is not a problem, you can use http://translatorservice.codeplex.com/

The Bing Speech Control for Windows 8.1 has a nearly identical API set to that of the speech recognition APIs on Windows Phone. It is not difficult to create an abstraction around them that can work in a universal app. Unfortunately the speech control for Windows 8 does require an internet connection for speech recognition.

For text to speech only (not recognition), those APIs were added directly to Windows 8.1. They are in the Windows.Media.SpeechSynthesis namespace.
