1. Estimation of Speaker Age : Effects of Speech Properties and Speech Material
Sammanfattning : The aim of this thesis was to investigate factors related to accuracy in estimation of speaker age and the role of certain speech properties in perception and manipulation of speaker age, as well as their interaction with the speech material that the age estimates were based on. This thesis consists of three studies. LÄS MER
2. Entropy and Speech
Sammanfattning : In this thesis, we study the representation of speech signals and the estimation of information-theoretical measures from observations containing features of the speech signal. The main body of the thesis consists of four research papers. Paper A presents a compact representation of the speech signal that facilitates perfect reconstruction. LÄS MER
3. 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
4. Swedish speech rhythm in a cross-language perspective
Sammanfattning : The study aims to describe and to explain some temporal aspects of the rhythmic structure of Swedish, and to compare Swedish, Spanish, and Finnish, characterized as rhythmically different languages.The temporal effects of some manipulations believed to have consequences for rhythm were studied in a series of experiments based on sets of Swedish sentences.

5. Human perception in speech processing
Sammanfattning : The emergence of heterogeneous networks and the rapid increase of Voice over IP (VoIP) applications provide important opportunities for the telecommunications market. These opportunities come at the price of increased complexity in the monitoring of the quality of service (QoS) and the need for adaptation of transmission systems to the changing environmental conditions.
