Inside Macintosh: Speech Recognition Manager /

Chapter 1 - Speech Recognition Manager

Using the Speech Recognition Manager

This section illustrates basic ways of using the Speech Recognition Manager. In particular, it provides source code examples that show how you can

• determine whether the Speech Recognition Manager is available
• open a recognition system and a recognizer
• build a language model to define the words and phrases your application wants to listen for
• set that model as the active language model
• start and stop listening
• handle recognition results using an Apple event handler or a speech recognition callback routine
• interpret the data passed to your application in a recognition result
• save a language model (or other language object) into a resource or data file, and read that object from that file

Note

The code examples shown in this section provide only very rudimentary error handling.
