21. The acquisition of contrast : a longitudinal investigation of initial s+plosive cluster development in Swedish children
Sammanfattning : This Thesis explores the development of word-initial s+plosive consonant clusters in the speech of Swedish children between the ages of 1;6 and 4;6. Development in the word-initial consonant clusters is viewed as being determined by 1) the children’s ability to articulate the target sequence of consonants, 2) the level of understanding of which acoustic features in the adult model production are significant for the signalling of the intended distinction, and 3) the children’s ability to apply established production patterns only to productions where the acquired feature agrees with the adult target, to achieve a contrast between rival output forms.

22. Enabling Perceptions of Management Controls : Evidence from International Development Programs
Sammanfattning : A key challenge for management accounting and control is the extent to which the control’s intentions correlate with how it is received and perceived by those who are subject to it. Building on Adler & Borys’ (1996) enabling and coercive bureaucracy, this thesis explores the role of perception; that is, local actors consider controls as enabling their work instead of privileging only those at the top.

23. Distribution Preserving Quantization
Sammanfattning : In the lossy coding of perceptually relevant signals, such as sound and images, the ultimate goal is to achieve good perceived quality of the reconstructed signal, under a constraint on the bit-rate. Conventional methodologies focus either on a rate-distortion optimization or on the preservation of signal features. LÄS MER
24. Forensic comparison of voices, speech and speakers : tools and methods in forensic phonetics
Sammanfattning : This thesis has three main objectives. The first objective (A) includes Study I, which investigates the parameter fundamental frequency (F0) and its robustness in different acoustic contexts by using different measures. LÄS MER
25. Towards flexible audio coding
Sammanfattning : thesis is about audio coding and improving flexibility thereof. Audio coding is used to reduce the bit rate needed to represent audio signals in digital format. When the available bit rate is low, parametric coding methods that use models to describe perceptually-important features of audio signals have shown their efficiency. LÄS MER
