Shows how to implement continuous voice recognition and Speech Synthesis. |
Shows how to implement continuous voice recognition and Speech Synthesis, using a keyword-based constraint list, and the Speech Synthesizer to provide an spoken prompt. The event handler is set to change the color of the cube to a different color, based on voice input (eg, the user saying "red", "green", "blue".) Due to the lack of directional lighting, this produces a uniformly colored/lit cube of the requested color.
Note: This sample is part of a large collection of UWP feature samples. You can download this sample as a standalone ZIP file from docs.microsoft.com, or you can download the entire collection as a single ZIP file, but be sure to unzip everything to access shared dependencies. For more info on working with the ZIP file, the samples collection, and GitHub, see Get the UWP samples from GitHub. For more samples, see the Samples portal on the Windows Dev Center.
The sample demonstrates how to construct a constraint list, compile it, start continuous recognition, handle events in response to incoming speech, evaluate the confidence that the speech engine has provided, and handle errors. It also demonstrates how to construct a speech synthesizer, and hook it up to XAudio2 for output to the user.
This sample uses the microphone app capability in order to access the user's voice input.
Note The Windows universal samples for Windows 10 Holographic require Visual Studio to build, and a Windows Holographic device to execute. Windows Holographic devices include the Microsoft HoloLens and the Microsoft HoloLens Emulator.
To obtain information about Windows 10 development, go to the Windows Dev Center.
To obtain information about the tools used for Windows Holographic development, including Microsoft Visual Studio and the Microsoft HoloLens Emulator, go to Install the tools.
The following types are used in this code sample:
Client: Windows 10 Holographic build 14393
Phone: Not supported
- If you download the samples ZIP, be sure to unzip the entire archive, not just the folder with the sample you want to build.
- Start Microsoft Visual Studio and select File > Open > Project/Solution.
- Starting in the folder where you unzipped the samples, go to the Samples subfolder, then the subfolder for this specific sample, then the subfolder for your preferred language (C++, C#, or JavaScript). Double-click the Visual Studio Solution (.sln) file.
- Press Ctrl+Shift+B, or select Build > Build Solution.
The next steps depend on whether you just want to deploy the sample or you want to both deploy and run it.
- Click the debug target drop-down, and select Microsoft HoloLens Emulator.
- Select Build > Deploy Solution.
- Developer unlock your Microsoft HoloLens. For instructions, go to [Enable your device for development] (https://msdn.microsoft.com/windows/uwp/get-started/enable-your-device-for-development#enable-your-windows-10-devices).
- Find the IP address of your Microsoft HoloLens. The IP address can be found in Settings > Network & Internet > Wi-Fi > Advanced options. Or, you can ask Cortana for this information by saying: "Hey Cortana, what's my IP address?"
- Right-click on your project in Visual Studio, and then select Properties.
- In the Debugging pane, click the drop-down and select Remote Machine.
- Enter the IP address of your Microsoft HoloLens into the field labelled Machine Name.
- Click OK.
- Select Build > Deploy Solution.
The first time you deploy from your development PC to your developer-unlocked Microsoft HoloLens, you will need to use a PIN to pair your PC with the Microsoft HoloLens.
- When you select Build > Deploy Solution, a dialog box will appear for Visual Studio to accept the PIN.
- On your Microsoft HoloLens, go to Settings > Update > For developers, and click on Pair.
- Type the PIN displayed by your Microsoft HoloLens into the Visual Studio dialog box and click OK.
- On your Microsoft HoloLens, select Done to accept the pairing.
- The solution will then start to deploy.
- To debug the sample and then run it, follow the steps listed above to connect your developer-unlocked Microsoft HoloLens, then press F5 or select Debug > Start Debugging. To run the sample without debugging, press Ctrl+F5 or select Debug > Start Without Debugging.
