“…A direct way of inducing affective arousal and studying the effects of the voice is the use of psychoactive drugs. Thus, Helfrich et al (1984) studied the effects of antidepressive drugs on several vocal parameters (compared to placebo) over a period of several hours. Most induction studies have used indirect paradigms that include stress induction via difficult tasks to be completed under time pressure, the presentation of emotioninducing films or slides, or imagery methods (Alpert et al, 1963;Bachorowski and Owren, 1995;Bonner, 1943;Havrdova and Moravek, 1979;Hicks, 1979;Karlsson et al, 1998;Markel et al, 1973;Plaikner, 1970;Roessler and Lester, 1979;Scherer, 1977Scherer, , 1979Scherer et al, 1985;Skinner, 1935;Tolkmitt and Scherer, 1986).…”

The current state of research on emotion effects on voice and speech is reviewed and issues for future research efforts are discussed. In particular, it is suggested to use the Brunswikian lens model as a base for research on the vocal communication of emotion. This approach allows one to model the complete process, including both encoding (expression), transmission, and decoding (impression) of vocal emotion communication. Special emphasis is placed on the conceptualization and operationalization of the major elements of the model (i.e., the speakerÕs emotional state, the listenerÕs attribution, and the mediating acoustic cues). In addition, the advantages and disadvantages of research paradigms for the induction or observation of emotional expression in voice and speech and the experimental manipulation of vocal cues are discussed, using pertinent examples drawn from past and present research.

Speech consists not only of linguistic elements such as phonemes – it also contains features which carry nonlinguistic information. These features, e.g. voice quality and prosody, either occur spontaneously and are related to the speaker’s emotional and/or physiological state or are produced intentionally and related to the speaker’s attitudes or interaction strategies (even though the latter often include features that are meant to appear as unintentional). Acoustic analysis of the human voice thus allows the identification of vocal correlates of the speaker’s emotional and/or physiological state as well as of his social intentions.

Speech Characteristics in Depression

This study examined the relationship between speech characteristics and psychopathology throughout the course of affective disturbances. Our sample comprised 20 depressive, hospitalized patients who had been selected according to the following criteria: (1) first admission; (2) long-term patient; (3) early entry into study; (4) late entry into study; (5) low scorer; (6) high scorer, and (7) distinct retarded-depressive symptomatology. Since our principal goal was to model the course of affective disturbances in terms of speech parameters, a total of 6 repeated measurements had been carried out over a 2-week period, including 3 different psychopathological instruments and speech recordings from automatic speech as well as from reading out loud. It turned out that neither applicability nor efficiency of single-parameter models depend in any way on the given, clinically defined subgroups. On the other hand, however, no significant differences between the clinically defined subgroups showed up with regard to basic speech parameters, except for the fact that low scorers seemed to take their time when producing utterances (this in contrast to all other patients who, on the average, had a considerably shorter recording time). As to the relationship between psychopathology and speech parameters over time, we found significant correlations: (1) in 60% of cases between the apathic syndrome and energy/dynamics; (2) in 50% of cases between the retarded-depressive syndrome and energy/dynamics; (3) in 45% of cases between the apathic syndrome and mean vocal pitch, and (4) in 71 % of low scores between the somatic-depressive syndrome and time duration of pauses. All in all, single parameter models turned out to cover only specific aspects of the individual courses of affective disturbances, thus speaking against a simple approach which applies in general.
