CHoral - Access to oral history
Supervision: prof. dr. Franciska de Jong, dr. Roeland Ordelman CHoral aims at the development of spoken document retrieval technology for the disclosure of oral history collections. With speech recognition transcriptions can be generated for spoken documents (audio and video). The transcripts have timestamps associated with the words and will be used to build an index that allows searching the audio files at fragment level. This project aims to contribute to the advent of a methodological framework for handling and use of multimedia oral history content for historical research. Take a look at our first demo (in Dutch). It was developed in cooperation with the Netherlands Institute for War Documentation and the Netherlands Institute for Sound and Vision. A second CHoral demonstrator was developed in cooperation with the Netherlands Institute for War Documentation, the UT Databases group, and DNB Media. CHoral contributed to the interview access functionality of the Rotterdam 'Brandgrens' Website.
Leiden University: Dual-ProAs of September 1st 2008 I am also working for Leiden University on the FP-7 SME project DUAL-PRO: Dual electric-acoustic speech processor with linguistic assessment tools for deaf individuals with residual low frequency hearing. I am involved in the development of a prosodic test battery. TopEarlier projects
PhD project: The acquisition of phoneme contrasts in L1 and L2 This study will examine how the perception of new phoneme contrasts develops. In classification training, new L2 contrasts will be taught to children aged 12 and adults. There are two hypotheses on the development of phoneme categories. The first hypothesis, acquired distinctiveness, states that no distinctions between adjacent stimuli from a phoneme continuum can be heard before training. During training, perceptual sensitivity increases for stimuli that are categorized differently. This learning strategy is expected for adults. The second hypothesis, acquired similarity, states that all stimuli can be distinguished before training. Training causes a decrease in sensitivity for items that are categorized together. Infants are thought to show acquired similarity. The way in which children learn new contrasts, as they develop from infants to adults, is unclear. The participants’ ability to perceive stimuli from phoneme continua will be assessed in identification and discrimination tasks. With respect to L1, the perceptual development of Dutch 5 to 7-year-olds is studied. We use phoneme contrasts that are comparable to the ones studied in L2 development, and study how child perception differs from adult perception, and how child perception changes over time.
MA thesis: Intonation in whispered speech. Correlates of production and perception. In normal speech, the fundamental frequency with which the speaker's vocal folds vibrate is an important cue in intonation perception. In whispered speech, however, the vocal folds do not vibrate, and therefore the fundamental frequency cue in intonation perception is absent. In this study we addressed the question how intonation is conveyed in whispered speech. |
