Reco
Introduction
Reco is a speech tool that you can use to examine and test the speech process. You may speak using a microphone for either dictation or command and control. Alternatively, you may directly type a command and control order in an edit box and submit it to the speech recognition engine.
During the recognition process, events will be displayed in the top window as they occur. An event log is kept and to examine the details of each one, double-click the item. You may use this log to trace the sequence and number of events. You may also examine speech results. Double-click the text or phrase to display more detailed information about the text in the bottom window.

The dialog box presents several options. By default, all options are initially on. The following options display detailed information suited for speech testing.
