  2. 11. Perceptual and Squared Error Aspects in Speech and Audio Coding

    Author : Harald Pobloth; Bastiaan Kleijn; Gernot Kubin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; speech coding; audio coding; auditory models; perceptual distortion measures; squared error; Signalbehandling; Signal processing; Signalbehandling;

    Abstract : In the process of quantization, speech and audio signals are changed. This thesis contains four papers concerned with comparing and minimizing different measures to quantify the changes introduced. Before quantization the signal can be transformed to another domain. Transforms related to the discrete Fourier transform allow for e. READ MORE

  4. 12. Improving Quality of Service in Baseband Speech Communication

    Author : Petko Nikolov Petkov; W. Bastiaan Kleijn; Yannis Stylianou; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Speech and Music Communication; Tal- och musikkommunikation; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Abstract : Speech is the most important communication modality for human interaction. Automatic speech recognition and speech synthesis have extended further the relevance of speech to man-machine interaction. READ MORE

  5. 13. Developing and evaluating co-speech gesture-synthesis models for embodied conversational agents

    Author : Taras Kucherenko; Hedvig Kjellström; Gustav Eje Henter; Iolanda Leite; Jonas Beskow; Stefan Kopp; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Human-agent interaction; gesture generation; social robotics; conversational agents; non-verbal behavior; deep learning; machine learning; Computer Science; Datalogi;

    Abstract :  A  large part of our communication is non-verbal:   humans use non-verbal behaviors to express various aspects of our state or intent.  Embodied artificial agents, such as virtual avatars or robots, should also use non-verbal behavior for efficient and pleasant interaction.

  6. 14. Mapping Individual Voice Quality over the Voice Range : The Measurement Paradigm of the Voice Range Profile

    Author : Peter Pabon; Sten Ternström; Maria Södersten; Ingo Titze; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Voice Range Profile VRP ; Phonetogram; Voice Field; Voice quality; Singing voice; Voice synthesis; Clinical voice assessment; Sound level measurement; Maximum Entropy; Tal- och musikkommunikation; Speech and Music Communication;

    Abstract : The acoustic signal of voiced sounds has two primary attributes: fundamental frequency and sound level. It has also very many secondary attributes, or ‘voice qualities’, that can be derived from the acoustic signal, in particular from its periodicity and its spectrum. READ MORE

  7. 15. Filter bank design for digital speech signal processing : methods and applications

    Author : Jan Mark de Haan; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive filter theory; Subband filter banks;

    Abstract : Adaptive filter theory is an important subject in the field of signal processing and has numerous applications in speech processing, telecommunications and mechanical engineering. Examples in speech processing include suppression of background noise, echo cancellation and dereverberation (acoustic path equalization). READ MORE
