93 (Fig. a). These changes included the removal of the second peak rule as it usually resulted in halving errors, the use of an unbiased autocorrelation function (whose envelope does not decrease to zero at large lags [11]). 46 T. Bőhm, Z. Both, and G. 5. 2 Normalized RMS Amplitude (NRMS) In irregularly phonated speech, there are generally fewer glottal pulses in a given time frame than in regularly phonated speech. This can be captured by the RMS amplitude (intensity), normalized by the RMS amplitude of a longer interval.

It is likely that irregular phonation plays a role in various aspects of speech communication. It has been shown to be a cue to segmental contrasts and to prosodic structure in several languages [2]. Further, its occurrence seems to be characteristic to certain speakers [3] and to certain emotional states [4]. g. speech recognition, emotional state classification and speaker identification). J.

This indicates a sort of distortion that can be considered as an additive noise (note that the subjective measure coincide in that the happy style is affected by a distortion in such a manner its MOS for naturalness is below the other styles). Finally, the jitter results for the sad style indicates that the synthesized speech suffers from a trembling effect (concretely, the more utterances to adapt, the higher the jitter).
