Student assignments

Here are some available student assignments – note that these are general descriptions and can be adjusted such that they fit a certain type of assignment (bachelor graduation project / master graduation project / capita selecta / advanced research project / i-tech project) and that they fit the interests and skills of the student.

Analysis of depression in speech

The NESDO research (Nederlandse Studie naar Depressie bij Ouderen) was a large longitudinal Dutch study into depression in older adults (>60yr old). Older adults with and without depression were followed over a period of six years. Measurements included questionnaires, a medical examination, cognitive tests and information was gathered about mental health outcomes, demographic, psychosocial and cognitive determinants. Some of these measurements were taken in face-to-face assessments. After baseline measurement, face-to-face assessments were held after 2 and 6 years.

Currently, we have a few audio recordings available from the 6-yrs measurement from depressed and non-depressed older persons. We are looking for a student (who preferably has knowledge of Dutch) who is interested in performing speech analyses on these recordings with the eventual goal to detect depression automatically in speech.

This work will be carried out in collaboration with Dr. Paul Naarding, GGNet Apeldoorn.

Automatic Laughter analysis in human-Computer Interaction

Laughter analysis is currently a hot topic in Human-Computer Interaction. Computer scientists generally study how humans communicate through laughter and how this can be implemented in Automatic Laughter Detection and Automatic Laughter Synthesis. Development of such tools would be very helpful in fields like Human-Computer/Robot Interaction, where voice assistants like Alexa and Google assistant might understand more complex natural communication through the interpretation of social signals such as laughter and generating well timed and appropriate realistic laughter responses. Another application could be multi-media laughter retrieval, automatically extracting laughter occurrences from large amounts of video and audio data, opening the way for retrieving large laughter datasets. As a final example, laughter detection could also possibly be used to study group behavior or automatic person identification.

However there are several challenges in laughter research that need to be considered when aiming for automatic laughter analysis. For one, annotating laughter is a much discussed challenge for the field, there are debates on how laughter should be segmented and labeled. Are there different kinds of laughs for different situations and how do we label these? Do people have specific laughter profiles? How does context play a role in laughter detection? How could a real-time implementation in a conversational agent look like and for what purpose? Students can choose to go for a more human-centered or technology oriented direction.

This makes achieving automatic laugher analysis an interesting goal. Students are invited to explore the topic of Automatic Laughter analysis and come up with an interesting question or challenge they want to address. You will be supervised by assistant professor Khiet P. Truong, who is an expert in laughter research and SSP and PhD student Michel-Pierre Jansen whose PhD work evolves around human laughter recognition and Social Signal Processing.

Spoken Interaction with Conversational Agents and Robots

Speech technology for conversational agents and robots has taken a flight (e.g., Siri, Alexa), but we are not quite there yet. While there are technical challenges to address (e.g., how can an agent display listening behavior such as backchannels “uh-uhm”, how can we recognize a user’s stance/attitude/intent, how can we express intent without using words, how can an agent build rapport with a user), there are also more human-centered questions such as how to design such a spoken conversational interaction, how do people actually talk to an agent or robot, what effect does a certain agent/robot behavior (e.g., robot voice, appearance) have on a child’s perception and behavior in a specific context?

These are some examples of research questions we are interested in. Much more is possible. Are you also interested? Khiet Truong and Ella Velner can tell you more.
