In accordance with the present invention, a web server supports a client choice of audio or standard video presentation of essentially the same web content. A client passes information requesting web page content in a specific form, preferably as a newly defined argument to the URL called "pagetype". The pagetype may specify that the client wants text only, audio only, or wants both audio and text. Preferably, a new HTML tag "audiate" is defined. An audiate tag in the HTML stream of a web page indicates how an audio version of the web content will be constructed, and optionally indicates the conditions under which the audio version will be played to the user. Specifically, the audiate tag may include one or more optional parameters, among which are one specifying a wave file containing audio content, one specifying HTML elements to be converted to audio, and one specifying a time interval for repeating the audio presentation. The alternative audio format of a web page has many potential uses, including background audio presentation while the user is working on other tasks at a workstation, audio presentation to portable devices, simultaneous audio and video presentation as a teaching tool, and others.
