There are several reasons you might not hear sound when you click the "Audio" link.

The volume setting on your computer might be too low. To adjust the volume, click the speaker icon on the toolbar in the lower-right corner of your screen.

Or, you might need to install the QuickTime audio plug-in on your computer. Follow these steps to install:

2. Select your operating system, and click the "Download QuickTime" button.
3. Follow the installation instructions to complete the procedure.
4. During the installation process, you see the QuickTime Settings window in which you can assign file type associations. Under the "Select viewer associations" heading, check the "Windows file types" and "Macintosh file types" boxes, and then continue.
5. When the QuickTime installation is finished, launch your web browser and test audio pronunciation.
