Your Read Aloud text-to-speech preferences default to Voice: Lauren, and Speed: Normal. However, you can change the defaults for both the voice and the speed. Here's how:
Select "Preferences" from the My Account toolbox.
netTrekker SEARCH allows you to choose which of three voices, and which of three speeds you would like to use.
Click on the drop-down box to select from the three voices available. You can listen to a sample of each voice by clicking on the link at the bottom the page which says, "Listen to a pregenerated sample of each voice here."
Choose the radio button for the speed at which you want the text to be read.
Once you have selected a preferred voice and/or speed, click this button to implement your change.
