The Client Library
The Speech-to-Text client library is a thin C# client wrapper for Bing Speech API.
The easiest way to use this client library is to get microsoft.projectoxford.speechrecognition package from nuget. There are two nuget packages. One is for x86 build, and one is for x64 build. * For x86 package, please go to Speech Recognition API x86 Package in nuget for more details. * For x64 package, please go to Speech Recognition API x64 Package in nuget for more details.
This sample is a Windows WPF application to demonstrate the use of Speech-to-Text in the Bing Speech API. It demonstrates the following features using a wav file or external microphone input: * Short-form recognition * Long-form dictation * Recognition with intent
Build the sample
Start Microsoft Visual Studio 2015 and select
File > Open > Project/Solution.
Navigate to the folder where you cloned the repository.
Double-click the Visual Studio 2015 Solution (.sln) file SpeechToText-WPF-Sample.
Choose the build flavor to be x64. This is important because the sample is using Microsoft.ProjectOxford.SpeechRecognition-x64 nuget package by default.
Press Ctrl+Shift+B, or select
Build > Build Solution.
For intent recognition to work, you need to sign up Language Understanding Intelligent Service (LUIS). Please put your LUIS App ID and Subscription ID in app.config file. app.config file can be located from Solution Explorer.

After the build is complete, press F5 to run the sample.
