You can find spoken word recordings in the University Libraries' using OneSearch's advanced search. You can search for a specific work using its title as a search term, or an author using his or her name, or you can use search terms that express a subject or topic that interests you.
Prior to running your search, however, choose "audio recording" from the "content type" filter.
If you are specifically interested in hearing a writer read his or her own work, you will need to examine the search results to find out who is the reader of each recording.
