![]() SpeechRecognizer.LoadGrammar(new Grammar(grammarBuilder)) ValueChoices.Add("small", "medium", "large") ValueChoices.Add("red", "green", "blue") Here's the code: GrammarBuilder grammarBuilder = new GrammarBuilder() Ĭhoices commandChoices = new Choices("weight", "color", "size") #Azure speech to text tutorial codeShow you the entire code sample, I want to focus on the way we add the commands to the engine. Value, which in this case will be used to change the color, size and weight of the text in a Label control, solely based on your voice commands. The idea is that it should listen for two words: A command/property and a In the next example, we'll feed a set of commands into the recognition engine. ![]() Instead, it will use basic voice recognition and listen only for grammar which you feed into the class. #Azure speech to text tutorial windowsA huge differenceīetween the two is that the SpeechRecognitionEngine class doesn't require the Windows speech recognition to be running and won't take you This also means that dictation will be ignored completely, even though text input fields have focus.įor this purpose, we will use the SpeechRecognitionEngine class instead of the SpeechRecognizer class. So while the above examples have been focusing on dictation and interaction with UI elements, this next example will focus on the ability to listen for and Windows will then try to distinguishīetween dictation and commands, but this can of course be difficult in certain situations. In the above example, Windows will automatically go into dictation mode as soon as focus is given to a text box. While at the same time invoking commands from the user interface - pretty cool indeed! Specific commands This actually allows you to dictate text to the TextBox, You can try running the example and then speaking out one of the commands, e.g. MessageBox.Show("Command invoked: Save") Private void btnSave_Click(object sender, RoutedEventArgs e) MessageBox.Show("Command invoked: Open") Private void btnOpen_Click(object sender, RoutedEventArgs e) Private void btnNew_Click(object sender, RoutedEventArgs e) SpeechRecognizer recognizer = new SpeechRecognizer() Public SpeechRecognitionTextCommandsSample() Public partial class SpeechRecognitionTextCommandsSample : Window Here and turn your buttons into commands, reachable through speech, without any extra work. This first example will allow you to dictate text to your application, which is great, but what about commands? Windows and WPF will actually work together If you haven't used speech recognition on your computer before, then Windows will take you through a guide which will help you get started and make ![]() This is actually all you need - the text in the screenshot above was dictated through my headset and then inserted into the TextBox control as text,Īs soon as you initialize a SpeechRecognizer object, Windows starts up its speech recognition application, which will do all the hard workĪnd then send the result to the active application, in this case ours. ![]() SpeechRecognizer speechRecognizer = new SpeechRecognizer() Public partial class SpeechRecognitionTextSample : Window Namespace WpfTutorialSamples.Audio_and_Video With that taken care of, let's start out with an extremely simple speech recognition example: Depending on which version of Visual Studio you use, the This assembly is not a part of your solutions by default, but we can easily add it. To do that, we'll be using the SpeechRecognition class, which resides in the System.SpeechĪssembly. Way around, by turning spoken words into text. In the previous article we discussed how we could transform text into spoken words, using the SpeechSynthesizer class. Audio & Video: Speech recognition (making WPF listen) ![]()
