2. From Acoustics to Articulation : Study of the acoustic-articulatory relationship along with methods to normalize and adapt to variations in production across different speakers
Sammanfattning : The focus of this thesis is the relationship between the articulation ofspeech and the acoustics of produced speech. There are several problems thatare encountered in understanding this relationship, given the non-linearity,variance and non-uniqueness in the mapping, as well as the differences thatexist in the size and shape of the articulators, and consequently the acoustics,for different speakers.

3. Robots Beyond Borders : The Role of Social Robots in Spoken Second Language Practice
Sammanfattning : This thesis investigates how social robots can support adult second language (L2) learners in improving conversational skills. It recognizes the challenges inherent in adult L2 learning, including increased cognitive demands and the unique motivations driving adult education. LÄS MER
4. Computational Modeling of the Vocal Tract : Applications to Speech Production
Sammanfattning : Human speech production is a complex process, involving neuromuscular control signals, the effects of articulators' biomechanical properties and acoustic wave propagation in a vocal tract tube of intricate shape. Modeling these phenomena may play an important role in advancing our understanding of the involved mechanisms, and may also have future medical applications, e. LÄS MER
5. Perceptually motivated speech recognition and mispronunciation detection
Sammanfattning : This doctoral thesis is the result of a research effort performed in two fields of speech technology, i.e., speech recognition and mispronunciation detection. Although the two areas are clearly distinguishable, the proposed approaches share a common hypothesis based on psychoacoustic processing of speech signals. LÄS MER
