  3. 2. Domain Adaptation for Attention Steering

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Johanna Wilroth; [2020]
    Keywords : Technology and Engineering;

    Abstract : A major problem in the development of intelligent hearing aids is often referred to as the cocktail party problem. It describes the remarkable ability of the human brain of filter out unwanted sounds in a noisy environment, while focusing on a single talker or conversation. READ MORE

  4. 3. Beamforming and Blind Signal Separation for Far-field Voice Capture using a Microphone Array

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Luke Postema; Johan Davidsson; [2019]
    Keywords : Beamforming; Microphone array; Minimum variance distortionless response; delay-and-sum; direction of arrival; blind signal separation; Technology and Engineering;

    Abstract : With the evolving technology of mobile electronics and other forms of communication methods, an increasing demand of speech intelligibility is introduced. In a conference room for example, multiple microphones are placed directly in front of the speaker in order to pick up clean speech. However, several challenges still exist. READ MORE

  6. 5. Speaker Separation Investigation

    University essay from Blekinge Tekniska Högskola/Avdelningen för telekommunikationssystem

    Author : Fazal-e-Abbas Chaudhry; [2007]
    Keywords : Speaker Separation; Acoustics; Cross-correlation; Automatic Speech Recognition; Room Impulse Response; Maximal Length Sequences; Chirps;

    Abstract : This report describes two important investigations which formed part of an overall project aimed at separating overlapping speech signals. The first investigation uses chirp signals to measure the acoustic transfer functions which would typically be found in the speaker separation project. READ MORE
