How do listeners segment the continuous speech input into words? This paper addresses this important question by reviewing current views of lexical segmentation. After providing some background to the more general problem of spoken word recognition, we examine the different cues - including phonetic, phonological, prosodic, and lexical cues - that have been shown to play a role in speech segmentation. We then analyze how these cues are used to locate alignment points in the continuous speech signal. These points serve to define what parts of the signal are matched with which representations in the mental lexicon. Several solutions to the alignment problem are discussed in light of existing experimental evidence.
