One important aspect that differentiates CSR from DUR is that
boundaries between words are not well defined
-
Since words are spoken in a continuous manner there will be
various speaking rates depending upon the speaker
-
Word decisions can be made as the talker is speaking and is
called early decision
-
In deferred decision, no word decisions are made until
the speaker pauses and recognition are made for the words till
that pause
-
Since any sequence of words can be spoken over any length of
time number of searches required to recognize a word increases
drastically

For a V word vocabulary having K reference prototypes per word
and utterances of up to L words requires KVL
searches to match each utterance
