About Me

How people talk and understand each other has always fascinated me. The big question for me is how to develop technology that understands spoken language: how can we make automatic speech recognition more intelligent?. Besides what is said, there is also a lot of information in how something is said: aspects of physical, emotional, and mental states resonate in the voice, both consciously and unconsciously. I am particularly interested in the automatic interpretation of this implicit information, with the aim of, for example, enabling conversational agents (such as Siri) to respond more appropriately to children or older adults, or to develop apps that offer remote support to people suffering from depression.

After studying Linguistics (specialisation Language and Speech Technology) in Utrecht, I ended up at TNO where I investigated automatic emotion recognition in speech. Then I went to the University of Twente, Human Media Interaction where I am still working on the automatic analysis of nonverbal aspects in speech communication (e.g. laughing, backchanneling) in human-human, and human-machine interaction. Besides doing research I also teach speech processing, affective computing, and interaction technology.

Research

My research mainly focuses on automatically analyzing and interpreting nonverbal aspects in speech communication that say something about how the conversation is going, and what someone's physical, socio-emotional, and mental state is. My goal is to make automatic speech recognition more intelligent. Among other things, I have worked on automatic detection of laughter, automatic emotion recognition in speech, and automatic generation of backchannels for artificial agents. Currently, I am supervising a number of PhD students who are researching multimodal emotion expression in older adults, and responsible design for child-robot interaction. I am also supervising master students in their research on technology for vulnerable people (e.g. people with dementia, people with multiple disabilities), and human-robot interaction.
