This function doesn't reliably find all NPs within an utt,
typically, it finds more, since it doesn't recognize
complex NPs e.g. NPs modified by relative clauses,
genetive NPs or PPs.
Short NPs consisting only of a noun and immediately
following another NP are analyzed as part of the preceding NP.
The function is needed to predict phrase breaks, which are
typically inserted after NPs, although they can also occur
within complex NPs before NP-internal constituents, so the
problems mentioned above are less crucial.
