1. 1. Talking Heads - Models and Applications for Multimodal Speech Synthesis

   Författare :Jonas Beskow; KTH; []
   Nyckelord :Talking heads; facial animation; speech synthesis; coarticulation; intelligibility; embodied conversational agents;

   Sammanfattning : This thesis presents work in the area of computer-animatedtalking heads. A system for multimodal speech synthesis hasbeen developed, capable of generating audiovisual speechanimations from arbitrary text, using parametrically controlled3D models of the face and head. LÄS MER

3. 2. Bringing the avatar to life : Studies and developments in facial communication for virtual agents and robots

   Författare :Samer Al Moubayed; Jonas Beskow; Stefan Kopp; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Avatar; Speech Communication; Facial animation; Nonverbal; Social; Robot; Human-like; Face-to-face; Prosody; Pitch; Prominence; Furhat; Gaze; Head-pose; Dialogue; Interaction; Multimodal; Multiparty; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : The work presented in this thesis comes in pursuit of the ultimate goal of building spoken and embodied human-like interfaces that are able to interact with humans under human terms. Such interfaces need to employ the subtle, rich and multidimensional signals of communicative and social value that complement the stream of words – signals humans typically use when interacting with each other.

4. 3. Performance, Processing and Perception of Communicative Motion for Avatars and Agents

   Författare :Simon Alexanderson; Jonas Beskow; John Glauert; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tal- och musikkommunikation; Speech and Music Communication;

   Sammanfattning : Artificial agents and avatars are designed with a large variety of face and body configurations. Some of these (such as virtual characters in films) may be highly realistic and human-like, while others (such as social robots) have considerably more limited expressive means. LÄS MER

5. 4. Towards conversational speech synthesis : Experiments with data quality, prosody modification, and non-verbal signals

   Författare :Bajibabu Bollepalli; Joakim Gustafsson; Jonas Beskow; Matthew Aylett; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Speech synthesis; MPEG compression; Voice Conversion; Artificial Neural Net- works; Laughter synthesis; HTS; Computer Science; Datalogi;

   Sammanfattning : The aim of a text-to-speech synthesis (TTS) system is to generate a human-like speech waveform from a given input text. Current TTS sys- tems have already reached a high degree of intelligibility, and they can be readily used to read aloud a given text. For many applications, e.g. LÄS MER

7. 5. Alternative Measures of Phonation: Collision Threshold Pressure and Electroglottographic Spectral Tilt : Extra: Perception of Swedish Accents

   Författare :Laura Enflo; David House; Jonas Beskow; Sten Ternström; Francisco Lacerda; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustics; Akustik;

   Sammanfattning : The collision threshold pressure (CTP), i.e. the smallest amount of subglottal pressure needed for vocal fold collision, has been explored as a possible complement or alternative to the now commonly used phonation threshold pressure (PTP), i.e. LÄS MER
