In this article, I explain how to retrieve parameters when it is necessary to execute the voice commands and how to update phrase lists within the app. I also explain how to use speech recognition and text-to-speech features. This way, you will be able to combine voice commands, speech recognition, and text-to-speech to enable a voice-driven UX.

Checking Parameters and Executing Voice Commands

The Recipes app discussed in the first two parts of this series recognizes voice commands, but fails when it has to navigate to the target pages because the pages don't yet exist in the project. It is time to add the pages for each of the voice commands. I'll start with the simple AddNewRecipePage page that the app must display when executing the CreateNewRecipe voice command. To keep the sample app simple and focused on speech-related features, I won't use a Model-View-ViewModel (MVVM) approach - I'll just add the necessary pieces of code to the code-behind files. However, take into account that a MVVM approach is definitely suitable for these kinds of apps.
