Learning Microsoft Cognitive Services - Second Edition

Overview of this book

Microsoft has revamped its Project Oxford to launch the all new Cognitive Services platform-a set of 30 APIs to add speech, vision, language, and knowledge capabilities to apps. This book will introduce you to 24 of the APIs released as part of Cognitive Services platform and show you how to leverage their capabilities. More importantly, you'll see how the power of these APIs can be combined to build real-world apps that have cognitive capabilities. The book is split into three sections: computer vision, speech recognition and language processing, and knowledge and search. You will be taken through the vision APIs at first as this is very visual, and not too complex. The next part revolves around speech and language, which are somewhat connected. The last part is about adding real-world intelligence to apps by connecting them to Knowledge and Search APIs. By the end of this book, you will be in a position to understand what Microsoft Cognitive Service can offer and how to use the different APIs.

Verifying a person through speech


The process of verifying if a person is who they claim to be is quite similar to the identification process. To show how it is done, we will create a new example project, as we do not need this functionality in our smart-house Application.

Add the Microsoft.ProjectOxford.SpeakerRecognition and NAudio NuGet packages to the project. We will need the Recording class, which we used earlier, so copy this from the smart-house application's Model folder.

Open the MainView.xaml file. We need a few elements in the UI for the example to work. Add a Button element to add speaker profiles. Add two Listbox elements. One will hold available verification phrases, while the other will list our speaker profiles.

Add Button elements for deleting a profile, starting and stopping enrollment recording, resetting enrollment, and starting/stopping verification recording.

In the ViewModel, you will need to add two ObservableCollection properties: one of type string, the other of type...
