I'd be cautious about forcing user-agents to generate speech cues that  
are not, per-say, intrinsic to the authored content. For example, well- 
known structures such as lists and tables are usually exposed via  
screen-readers using special audio/speech cues (with configurable  
verbosity to meet user needs / preferences). Extra cues may also be  
generated to facilitate non-linear navigation of complex information  
structures (this is clearly out-of-scope in CSS, but it does overlap  
with the "begin/end level" concept you are describing). We can't  
possibly enumerate every possible way to announce well-defined  
structure points. So I agree with Fantasai about inserting additional  
text at the right places (should this be the author's wish). I assume  
you implied using CSS-generated content, right ? I also agree with not  
reading the shape name before each list item (proper reply in a  
separate email, coming soon). Regards, Daniel
