Phonetic explanations for the development of tones

The development of contrastive tone because of the articulatory reinterpretation of segmentally-caused perturbations in intrinsic fundamental frequency is well attested in a number of unrelated languages. Considering the wide-spread character of this process, it is likely that its ‘seeds’ can be found in the functioning of the human articulatory and/or auditory mechanisms. This paper reviews what the authors consider promising explanations for well-attested tonal sound patterns, e.g. tone originating from the effect of prevocalic stop consonants or postvocalic glottal consonants, and tone rarely or never originating from the influence of postvocalic non-glottal consonants or from vowel height.
