ER performance using region-wise syllable-level features is obtained by combining
the measures from the ERSs developed using initial, middle, and final syllables.
The performance of ERSs developed using region wise syllable-level, global and
local prosodic features is shown in Table 3.14 . In this study, three sets of studies are
carried out similar to the studies on utterance-wise syllable level emotion recognition.
Initial, middle and final syllablemodels are developed using global and local prosodic
features derived from the syllables of the initial words of the utterance. Similarly,
syllable models are developed using global and local prosodic features derived from
the syllables of middle and final words. In Table 3.14 , these results are shown in
separate rows. From the table, it is observed that the syllables of the final words carry
