Hello Lisa,
Express Dictate has the option to send dictations by email, to an FTP server or you can use the Express Delegate program from NCH to transfer dictations directly to Express Scribe, the person that has Express Dictate will have to download and setup Express Delegate to be able to transfer dictations directly to you.
You can find out more about Express Delegate Here:

Hope this helps! Good Luck!
