Stops are not identified in the same way depending on preceding fricatives. According to Mann and Repp (1981), such context-dependent variations in the perception of stops originate from the influence of fricatives on how stops are produced. This study aimed further to explore this hypothesis. A first experiment showed that the effect of fricatives on the identification of stops tends to be confined to the most ambiguous stimuli, when a large range of acoustic cues to place of stop articulation is provided to the listener. In a second experiment, articulatory and acoustic data were gathered in the production of fricative-stop sequences. Although on the whole consistent with previous findings, our results indicate that many articulatory dimensions are brought into play in fricative-stop articulatory patterns, thus making it difficult to establish a direct link between the articulatory and perceptual levels.
