Speech Prosody 2004
The gradual behaviour of articulatory supralaryangeal variations as a function as an 8-level vs a 4-level prosodic hierarchy was analysed here. Comparisons between the results related to each hierarchy suggested that 4-level hierarchy was sufficient to account for prosodic-dependent articulatory changes in French. These results allowed to discuss the architecture of hierarchical prosodic representation of speech.
