Voice

The voice Ascendis Caller ID will use when speaking.  You can hear a sample of the voice by clicking the play button () to the right of the voice selection.

Settings

If visible and enabled, lets you change settings for the selected voice.  This is provided with the speech engine and is not controlled by Ascendis Caller ID.  The standard voice included with Windows XP does not let you change the settings.

Speed

Specifies the rate at which Ascendis Caller ID speaks.  Move the control to the left (towards "Slow") to make it speak more slowly, or to the right (towards "Fast") to make it speak more quickly.  The Play button (next to the voice selection) will reflect the selected speed setting.

Preload speech support every ___ minutes

May decrease the time between the phone ringing and Ascendis Caller ID speaking.  A fast computer running no other programs and with power management disabled will probably not benefit.  You will have to experiment to determine the most effective setting.  Note that this will inhibit the computers ability to sleep, if power management is enabled.
