2. 1. Probabilistic Modelling of Hearing : Speech Recognition and Optimal Audiometry

   Author : Svante Stadler; Arne Leijon; Stefan Stenfelt; KTH; []
   Keywords : auditory models; probabilistic modelling; speech modelling; human speech recognition; hearing aids; cochlear implants; psychoacoustics; diagnostic methods; optimal experiments; audiometry;

   Abstract : Hearing loss afflicts as many as 10\% of our population.Fortunately, technologies designed to alleviate the effects ofhearing loss are improving rapidly, including cochlear implantsand the increasing computing power of digital hearing aids. Thisthesis focuses on theoretically sound methods for improvinghearing aid technology. READ MORE

4. 2. Perceptually motivated speech recognition and mispronunciation detection

   Author : Christos Koniaris; Olov Engwall; Martin Cooke; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; feature extraction; feature selection; auditory models; MFCCs; speech recognition; distortion measures; perturbation analysis; psychoacoustics; human perception; sensitivity matrix; pronunciation error detection; phoneme; second language; perceptual assessment;

   Abstract : 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. READ MORE

5. 3. That voice sounds familiar : factors in speaker recognition

   Author : Erik J. Eriksson; Kirk P. H. Sullivan; Christopher Darwin; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; speaker recognition; accent; emotions; hearing; spectral moments; formant transitions; dialect; Cognitive science; Kognitionsvetenskap;

   Abstract : Humans have the ability to recognize other humans by voice alone. This is important both socially and for the robustness of speech perception. This Thesis contains a set of eight studies that investigates how different factors impact on speaker recognition and how these factors can help explain how listeners perceive and evaluate speaker identity.

6. 4. Computational models for intent recognition in robotic systems

   Author : Michele Persiani; Thomas Hellström; Sven Magg; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intent Recognition; Robotics; Plan Recognition; Speech; Affordances; Computer Science; datalogi;

   Abstract : The ability to infer and mediate intentions has been recognized as a crucial task in recent robotics research, where it is agreed that robots are required to be equipped with intentional mechanisms in order to participate in collaborative tasks with humans.Reasoning about - or rather, perceiving - intentions enables robots to infer what other agents are doing, to communicate what are their plans, or to take proactive decisions.

7. 5. Emotional Communication in the Human Voice

   Author : Henrik Nordström; Petri Laukka; Marc Pell; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; emotion recognition; vocal expression; speech; acoustic parameters; Psychology; psykologi;

   Abstract : Emotional communication is an important part of social interaction because it gives individuals valuable information about the state of others, allowing them to adjust their behaviors and responses appropriately. When people use the voice to communicate, listeners do not only interpret the words that are said, the verbal content, but also the information contained in how the words are said, the nonverbal content.
