        ABSTRACT:  Preparing words in speech production is normally a
        fast and accurate process. We generate them two or three per
        second in fluent conversation, and overtly naming a clear picture
        of an object can easily be initiated within 600 ms after picture
        onset. The underlying process, however, is exceedingly complex.
        The theory reviewed in this target article analyzes this process
        as staged and feedforward. After a first stage of conceptual
        preparation, word generation proceeds through lexical selection,
        morphological and phonological encoding, phonetic encoding and
        articulation itself. In addition, the speaker exerts some degree
        of output control by monitoring self-produced internal and
        overt speech. The core of the theory, ranging from lexical
        selection to the initiation of phonetic encoding, is captured in a
        computational model, called WEAVER++. Both the theory and the
        computational model have been developed in conjunction with
        reaction time experiments, particularly in picture naming or
        related word production paradigms with the aim of accounting for
        the real-time processing in normal word production. A
        comprehensive review of theory, model and experiments are
        presented. The model can handle some of the main observations in
        the domain of speech errors (the major empirical domain for most
        other theories of lexical access), and the theory also opens new
        ways of approaching the cerebral organization of speech production
        by way of high-resolution temporal imaging.
