Emotions as a component of prosody
Original language description
Prosody is one of the factors which make natural and synthetic speech sound differently. Apart from frequently used prosodic parameters, such as fundamental frequency, speech unit duration and intensity, other parameters related to prosody, for example voice timbre, are also studied. Timbre is related to the expression of emotions in speech, but can be impacted by pathological changes as well. The timbre, characteristic of each individual, is based on higher formant frequencies, which are a result of signal modification in vocal organs, reverberation in cranial cavity, but also lip and tongue position variations. A direct expression of emotions is problematic in Text-to-Speech (TTS) synthesis. Emotions are coded in speech signal only, not in text. Theycan serve as one of the input parameters for prosody modelling by artificial neural networks (ANN) in TTS synthesis. The prosody will not reflect any specific emotion, but will increase the naturalness of speech.
