A Review of Personality in Voice-Based Man Machine Interaction

In this paper, we will discuss state-of-the-art techniques for personality-aware user interfaces, and summarize our own recent work in automatically recognizing and synthesizing speech with “personality”. We present an overview of personality “metrics”, and show how they can be applied to the perception of voices, not only the description of personally known individuals. We present use cases for personality-aware speech input and/ or output, and discuss approaches at defining “personality” in this context. We cover the state of the art in recognizing personality from speech, using an approach, which is very similar to other meta-data extraction schemes. We also discuss the difficulty of generating appropriate responses in an automatic dialog system, including work on generating consistency of what is being said, and how it is being said. To conclude, we present speculations about the future of this exciting area of ongoing research.
