  1. 1. Automatic acoustic tests of conference phones

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Carl Christian Kirchmann; [2017]
    Keywords : Acoustics; Digital signal processing; total harmonic distortion; reverberation;

    Abstract : This master thesis was completed at Limes Audio in Umeå. Limes Audio are specialized in speech enhancement software which is mostly used in conference phones. Their software is used to reduce noise, echo cancellation as well as reduction of distortion. READ MORE

  3. 2. A First Study on Hidden Markov Models and one Application in Speech Recognition

    University essay from Linköpings universitet/Matematisk statistik; Linköpings universitet/Tekniska fakulteten

    Author : Maria Servitja Robert; [2016]
    Keywords : Markov chain; Hidden Markov model HMM ; Speech recognition; MatLab simulation.;

    Abstract : Speech is intuitive, fast and easy to generate, but it is hard to index and easy to forget. What is more, listening to speech is slow. Text is easier to store, process and consume, both for computers and for humans, but writing text is slow and requires some intention. READ MORE

  4. 3. Implementation and Evaluation of Spectral Subtraction with Minimum Statistics using WOLA and FFT Modulated Filter Banks

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Peddi Srinivas Rao; Vallabhaneni Sreelatha; [2014]
    Keywords : Speech Enhancement; Filter Bank; Spectral Subtraction; Wiener Filtering; PESQ; DFT ; Master of Science Programme in Electrical Engineering with emphasis on Signal Processing Masterprogram i Elektroteknik med inriktning mot signalbehandling;

    Abstract : In communication system environment speech signal is corrupted due to presence of additive acoustic noise, so with this distortion the effective communication is degraded in terms of the quality and intelligibility of speech. Now present research is going how effectively acoustic noise can be eliminated without affecting the original speech quality, this tends to be our challenging in this current research thesis work.

  5. 4. Stereo Echo Cancellation(SEC) employing Signal Decorrelation with emphasis on Affine Projection Algorithm(APA)

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Santosh Ande; [2013]
    Keywords : Affine Projection Algorithm APA ; Stereo Echo Cancellation SEC ; De-correlation; Non-linear Processing NLP ; Time Varying All-Pass Filter TV-APF ; ERLE; MIS.;

    Abstract : Monophonic tele-conferencing systems employ acoustic echo cancellation (AEC) to reduce echoes that result from coupling between loudspeaker and microphone. Acoustic echo cancellation is simple to develope as there is a single channel. READ MORE

  6. 5. Performance analysis of different adapative algorithms based on acoustic echo cancellation

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Nagaswaroopa Adapa; Sravya Bollu; [2013]
    Keywords : Echo Cancellation; Adaptive algorithms; Noise Cancellation; Reverberation; Room Impulse Response; Adaptive filters;

    Abstract : In modern telecommunication systems like hands-free and teleconferencing systems, the problem arise during conversation is the creation of an acoustic echo. This problem degrades the quality of the information signal. READ MORE
