Laryngealization: characterization and interaction with other features

We studied the functioning of the larynx in the production of glottal stops and in the production of laryngealized voicing via an original approach to the quantification of this phonetic feature in running speech. We studied the interaction between vowel laryngealization and lexical tones and the interactions between glottal stops and flanking vowels. Both languages in which this feature distinguishes phonemes and languages in which this feature has a prosodic role were studied.
