With some voices, you can change the volume of windows screen readers,  
windows media player has independant volume control and voice over has  
on the fly volume control.

Another big problem when using a screen reader and playing a media  
file with sound is trying to control the volume of the media  
separately from the volume of the screen reader.  I believe that is a  
screen reader control feature needed to make playing media files  
easier.  The only screen reader that I know of that does this is the  
prototype from IBM's Chieko Asakawa called aiBrowser - see http://www.eclipse.org/actf/downloads/tools/aiBrowser/index.php

. . . Users can also adjust the volume of an individual source in  
order to identify and listen to different sound sources without losing  
track of the screen-reading software because of the sound of a video.  
If a content creator wants to provide a voice narrative for a video,  
he can write a text script as a piece of metadata; the tool adds the  
audio descriptions by using text-to-speech engines. Future plans for  
extending this technology include enabling flexible audio speed  
control and contributing this work to an open-source development  
project. Such contribution will accelerate development and adoption of  
tools that make Web-based multimedia content accessible to the  
visually impaired. . .
