I'm fuzzy on what "session" might mean.  In an IVR app it's kinda obvious -usually the duration of the call, or perhaps of a particular service request that spans calls.

But in the public web, it's unclear.  For example...

I open a web site in my browser and it's speech enabled.  My "session" exists for the entire duration of me using that site.  I close the browser and reopen it next week - same user, same device - and I'm still in the same session, right?

I open two different sites on the same device.  Both sites happen to use the same speech service at the back end.  They're different sites, so they're different sessions, right?  The back end is accumulating acoustic adaptation data for the user across both sessions, but contextual data is being kept separate.

Session doesn't make a lot of sense to me unless there is a start and a stop.  So if you disagree on this point, we have more to discuss.

Regarding possible implementation, cookies can be unset.

This seems reasonable to me, as long as it doesn't imply that there is a requirement for web apps or UAs to close the sessions. HTTP cookies does not have such a mechanism.
