1. Desktop
Speech technology can augment traditional graphical user interfaces. At its simplest, it can be used to provide audible prompts with spoken "Yes/No/OK" responses that do not distract the user's focus. But increasingly, complex commands are enabling rapid access to features that have traditionally been buried in sub-menus and dialogs. For example, the command "Use 12-point, bold, Helvetica font" replaces multiple menu selections and mouse clicks.
2. Telephony Systems
Speech technology is being used by many enterprises to handle customer calls and internal requests for access to information, resources and services.
Universal messaging systems can provide a single point of access to multiple media such as voice-mail, email, fax and pager messages. Such systems rely upon speech synthesis to read out messages over the telephone. For example: "Do I have any email?" "Yes, you have 7 messages including 2 high priority messages from the production manager." "Please read me the mail from the production manager." "Email arrived at 12:30pm...".
3. Personal and Embedded Devices
Speech technology is being integrated into a range of small-scale and embedded computing devices to enhance their usability and reduce their size. Such devices include Personal Digital Assistants (PDAs), telephone handsets, toys and consumer product controllers.
4. Speech and the Internet
The Java Speech API allows applets transmitted over the Internet or intranets to access speech capabilities on the user's machine. This provides the ability to enhance World Wide Web sites with speech and support new ways of browsing. Speech recognition can be used to control browsers, fill out forms, control applets and enhance the WWW/Internet experience in many other ways. Speech synthesis can be used to bring web pages alive, inform users of the progress of applets, and dramatically improve browsing time by reducing the amount of audio sent across the Internet.
