Homework (for 10/29)

Go to ELLLO: www.elllo.org.   Go through at least three different interviews at three different times in three different ways, spending at least 60 minutes total (of course more is better). Note that here are some tips for using the website:

• Try doing the quiz version first
• Try reading the transcript first
• Try the archives--you may find topics that interest you more there (click "interviews" at the top of the home page); explore the site in general
• If you find a topic you're familiar with and a speaker that's easy to understand, practice some dictation and check against the text
• Try downloading the mp3 and opening it with Windows Media Player so you have more control (pause, rewind, longer slidebar)
• Try listening at a slower speed: using Windows Media Player click on view>enhancements to find it

Send me the report of your experience (efs@stanford.edu) by 6:00 PM Monday the 29th.
