PAUSES — Analysis of pauses, utterances, loudness and dynamics
Determines the distributions of speech parameters, such as
duration of pauses and utterances, energy and dynamics, or mean
vocal pitch, in a speech recording, or in a set of recordings.
Speech parameters can be analysed within individuals or across
individuals for a prespecified experimental condition. All
parameter distributions can be visualized through bar charts.

Fig. 21: Mean utterance duration and mean pause duration describe
the statistical properties of speech flow. These parameters are
used to test the hypotheses that (1) patients speak more slowly
during depression than they do after recovery, and (2) number and
duration of temporary breaks decrease with recovery from
depression. It is worth noting, however, that speaking behavior
is a complex issue that cannot be reliably described by a single
parameter.
