Glottalization is often associated with low pitch in intonation languages, but evidence from many languages indicates that this is not an obligatory association. We asked speakers of German, English and Swedish to compare glottalized stimuli with several pitch contour alternatives in an AXB listening test. Although the low F0 in the glottalized stimuli tended to be perceived as most similar to falling pitch contours, this was not always the case, indicating that pitch perception in glottalization cannot be predicted by F0 alone. We also found evidence for cross-linguistic differences in the degree of flexibility of pitch judgments in glottalized stretches of speech.
