Please Note

Downloaded audio examples will arrive at your computer in Ogg Vorbis (.ogg) format. Most of the recent versions of Windows, Macintosh, and Unix/Linux operating systems contain audio players that will play .ogg files without requiring any format conversion. If your web browser cannot play .ogg files directly, downloading them to your computer and double-clicking on the file(s) will open an appropriate player, if you have one installed. If you find that your software does not play .ogg files, you can download a free .ogg player at http://www.vorbis.com or http://www.rarewares.org/ogg.html. You should also be able to play sound files directly by clicking on the live links in the PDF file of the article. If those links do not work properly, check to be sure you are using the latest version of Adobe Acrobat Reader; you can update your Reader at no cost at http://www.adobe.com.
