Inside Macintosh: Speech Recognition Manager /

Chapter 1 - Speech Recognition Manager

This chapter describes the Speech Recognition Manager, the part of the Macintosh system software that your application can use to respond to speech. You use the Speech Recognition Manager to define the words and phrases you want to listen for and to control other aspects of recognizing speech and reacting to successful recognitions.

To use this chapter, you should be familiar with the Apple Event Manager, as described in Inside Macintosh: Interapplication Communication. You need to know how to receive and process Apple events if you rely on the default behavior for being notified about the words and phrases recognized by the Speech Recognition Manager.

This chapter begins by describing the basic capabilities of the Speech Recognition Manager. Then it shows how to use some of those capabilities to recognize speech and to react to that speech. The section "Speech Recognition Manager Reference," beginning on page 1-35, provides a complete reference to the constants, data structures, and functions provided by the Speech Recognition Manager.

Note

This chapter describes the application programming interfaces supported by version 1.5 and later of the Speech Recognition Manager.
