1. 1. Implementation and evaluation of spectral subtraction (SS) with minimum statistics and wiener beamformer combination

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Venkata Rami Reddy Datla; [2013]
   Keywords : Direction Of Arrival DOA ; Wiener Beamformer; Microphone Array; SNRI ;

   Abstract : In mobile communication systems, speech signal can be distorted by acoustic noise such as babble speech noise. Such kind of noises can distort the quality of speech signal to a high extent. READ MORE

3. 2. Speech Enhancement in Hands-Free Device (Hearing Aid) with emphasis on Elko's Beamformer

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : TELAGAREDDI S N U V RAMESH; [2012]
   Keywords : Speech Enhancement; Speech intelligibility; Speech Communication and Beamforming ;

   Abstract : In general, an uncontrolled environment may contain degradation components like background noise, speech from other speakers etc. along with required speech components. It is very tough to concentrate only on speech signals in presence of background noise for normal listeners and hearing impaired persons. READ MORE

4. 3. Multi Channel Sub Band Wiener Beamformer

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Rajesh Amerineni; [2012]
   Keywords : Reverberation; Linear Microphone array; WOLA Filter Bank; Wiener Beamformer; SRP-PHAT;

   Abstract : With the recent advance in microphone array speech processing, achieving robustness of speaker localization becomes most significant aspect. At the same time considerable research growth is performed in developing the multiple microphone sensors equipped rooms are developed also called as smart rooms for real time applications. READ MORE

5. 4. Measuring Speech Quality of Laptop Microphone System using PESQ

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Praveen Lingapuram; [2012]
   Keywords : PESQ; wiener beamformer; spectral subtraction;

   Abstract : Signal compression algorithms are required in speech processing system to support the limited bandwidth requirements. And while compressing the signal, speech quality must not be degraded and modern speech methods makes use of perceptual information present in the signal to distinguish which part of the signal needs to be sent and which needs to be discarded.

6. 5. Simulation of microphone inaccuracies and robustness analysis of Beamformers inside a reverberant environment

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : ADITYA SRI TEJA PALANKI; [2012]
   Keywords : Speech Enhancement; Beamformer; Reverberation; Hearing Aids; Noise Cancellation; Fractional Delay; Binaural hearing; Source localization; Echo Cancellation;

   Abstract : All Speech Processing Equipments like noise cancelling headphones and Hearing aids should be able to filter different kinds of interfering signals and present a clear sound to the listener. The effect of these interfering signals varies depending on the surroundings. READ MORE
