In general, I think that the article covers main aspects of speaker recognition. However, some latest research topics were not addressed; e.g. long-term temporal features and dynamic features of speakers. I'd like to see those will be added after revision.
User 2 (Assistant Editor): symbol "?" in text
There are at least three question mark symbol (ascii code 63, on web browser firefox and chrome) in the middle of sentences before numbers such as "a slope equal to ? 1." Do they have a specific meaning? I don't understand why they are there at all. --Memming 18:04, 3 December 2008 (EST)
