secondary emotions definition
secondary emotions like empathy. As a means o engaging with social robots, empathy is particularl salient due to its nature of demonstrating emotion understanding and engagement, and has clear use i medical technology (James et al., 2018) and soci robots (Asada, 2015). This original research seeks t shed more light on the nature of empathy in speec using a parametric approach to synthesis. Althoug an older technique compared to machine learnin synthesis, it is found that this approach allows for greater degree of control over acoustic correlate and allows for a more precise image of empathy t emerge. This research splits empathy int production and perception; the first experimen looks at the difference between non-empathetic an empathetic contexts in a dialogue context with 1 participants (5 male and 5 female, in pairs), whic allows for the identification of empathetic correlate in natural speech production. Following this, a experiment using resynthesised versions of th non-empathetic productions explores whic combinations and amounts of the correlate observed in the first experiment (including pitc duration, and voice quality) must be used in order t elicit empathy. In doing so, it becomes clear th empathy is not a unified concept in speech, instea behaving differently within and between productio and perception.
