    Hi,

    How does one define a keyword spotter ? One way to look at it could be an
    engine that processes one complete
    utterance from start to end (like pocketsphinx for example) and checks if the
    keyword was spoken anywhere in that
    utterance.

    The other way to look at it is as an engine which keeps listening to the sound
    continuously (for however lengthy periods of times) and anytime a keyword is
    spoken it identifies it... so basically it always listens and hunts for a
    keyword.

    Which of the above will be termed as keyword spotter in speech recognition
    jargon and which of the schemes (or
    some other) is supported by say Sphinx-4 ?

    Thanks and regards,

    Hi,
    Both of them are keyword spotters. A keyword spotter looks for the keyword in
    an utterance, it is independent of when it reports it's finding.
    Both styles of implementation are possible to implement in sphinx-4
    (here is one such implementations).
