  2. 11. Speech and Video Coding for Unreliable Channels

    Author : Daniel Persson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; joint source-channel coding; channel-optimized quantization;

    Abstract : Speech and video communications via the Internet and cellular phones have become a part of modern life. This thesis deals with different methods for speech and video transmission over noisy and lossy communication channels. READ MORE

  4. 12. Subband Beamforming for Speech Enhancement in Hands-Free Communication

    Author : Zohra Yermeche; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Beamforming; Speech enhancement; Subband filtering;

    Abstract : Speech enhancement by means of microphone array signal processing has a major role in voice communication applications such as audio-conferencing, hands-free telephony, voice recognition and hearing aids. In these communication scenarios, the speaker is positioned at a remote distance from the microphones, which causes problems of environment noise and interfering sound corrupting the received speech.

  5. 13. Collaborating and communicating in new media - wiki's, social networks and blogs : a qualitative and quantitative approach

    Author : Gené van Heerden; Arthur Money; Luleå tekniska universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Industriell marknadsföring; Industrial Marketing;

    Abstract : The Web 2.0 environment has created a platform where the power and voice have shifted from organization to market. Communities, networks and the developments in information communication technologies have enabled the average consumer to become an active participant in creating and recreating value. READ MORE

  6. 14. Noise radiation from drill steels : and other experimental investigations in acoustics and fluid mechanics

    Author : Jan-Erik Ögren; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Drill rod noise has become a major noise source in percussive drilling. Generation of flexural waves, which seem to be responsible for most of the noise, is studied in a model with dynamic photoelasticity and in the real drill rod with strain gauge technique. READ MORE

  7. 15. Soft-Constrained Subband Beamforming for Speech Enhancement

    Author : Zohra Yermeche; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : New speech acquisition applications are emerging as a result of advances in technology and the prevalence of mobile communication. While today voice control of consumer equipment is becoming a reality, communication technology has extended voice connectivity to personal computers and mobile communication devices with the aim of enabling natural communication in a variety of environments such as cars, restaurants and offices.
