it would be great to start using scoped_ptr's support for passing ownership in
these methods.  Also, I would personally prefer to use the "Create" prefix
instead of "Get".  Can we change the method like so?

scoped_ptr<content::TtsDispatcherHostDelegate>
ChromeContentBrowserClient::CreateTtsDispatcherHostDelegate()

Imho GetSpeechRecognitionManagerDelegate should be renamed as well, so please
add a todo for me to fix it.  GetNetLog() and CreateAccessTokenStore() below are
appropriately named at least as far as Get vs Create goes.

Cool - done, and added the TODO for you.
