Amplitude and Amplitude Variation of Emotional Speech

The present study introduces a recording technique to maintain all dynamic information of even full-blown emotional speech, and investigates the effect of emotion class, speaker, and sentence type on the amplitude of speech. The results show that the factors emotion class and speaker are highly significant and that the former explains half of the variance while the latter explains only one ninth. Amplitude, as simple as it is, should therefore not be neglected or normalized in acoustic recordings and analyses of emotional speech.
