Blue Yonder

Introduction

This is an implementation of Microsoft Blue Yonder tutorial that comes with Beta 2 SDK The Microsoft .NET Speech SDK V1.0 Beta 2 contains:

• Tools for creating and debugging grammars and prompts.
• Sample applications and tutorials.
• ASP.NET controls for creating voice-only and multimodal SALT applications.
• Speech add-ins for Microsoft Internet Explorer browser software.
• New desktop version of the Microsoft speech recognition engine.
• The Microsoft Text-to-Speech (TTS) engine.

Creating a Speech Application

• Basic Steps to Adding Speech Functionality.
• Design an overall application flow (Web page structure and call flow for a telephone application).
• Create or import the basic ASP.NET input controls, database access code, and other standard application elements.
• Define the Grammar, the structured set of phrases that a user may say to the application.
• Define the Prompts, what the application says to the user in a voice-only environment.
• Use Speech Controls to integrate grammars and prompts and merge them with the Web application.
• These speech controls will also allow you to implement the overall dialog flow for a voice-only application.

Basic Steps for Building a Speech-Enabled Web Application

1. Set Speech Controls
2. Build Grammars
3. Define Prompts
4. Test and Run Application

Blue Yonder

In this simple web-based project, you will be speech-enabling a sample Web application that will allow a user to select their seat and meal preferences for a flight booking on a fictitious airline.

To run this program, you should have:

• IIS (Internet Information Services should be running)
• Then you install Microsoft Visual Studio .Net
• Afterthat, install The Microsoft .NET Speech SDK V1.0 Beta 2

Ive run it on Windows 2000 professional Service Pack 3 .. But it should work fine on Windows XP Service Pack 1.

In the IIS, you should create a virtual directory .. For the folder BYAirlines .. and in the visual studio .Net Solution Explorer make sure that the file WebForm1.aspx set as start page. The zip file should be extracted under the folder C:\Program Files\Microsoft .NET Speech without changing its name.

When you run this program you need a high quality microphone (USB Microphone is recommended) and you should press on the Speak Seat and Meal Request Box then you should say something like Give me OR I want a window seat and a vegetarian meal .. Then you should see your order written in the above two boxes.

Conclusion

I havent worked in any type of speech recognition projects before but after working with this tool I found things to be easier than what I thought of. In conclusion, I hope that you found this implementation to be useful for you.. at least you dont have to write the code .. Just concentrate on understanding it.
