1. Acoustic echo cancellation inside a truck cabin
Master-uppsats, Linköpings universitet/Statistik och maskininlärningSammanfattning : In the modern world, a day without telecommunication is almost unimaginable. A telecommunication system is used in almost every sector. In earlier days only luxury cars had the feature of a hands free communication but now it has become one of the basic requirements in any segment of vehicles. LÄS MER
2. Combining Acoustic Echo Cancellation and Voice Activity Detection in Social Robotics
Master-uppsats, KTH/Matematik (Avd.)Sammanfattning : This thesis is partly a theoretical introduction to some basic concepts of signal processing such as the Fourier transform, linear time invariant systems and spectral analysis of random signals, both in the continuous and discrete setting. A second part is devoted to theory and applications of echo cancellation and voice activity detection in so called social robotics. LÄS MER
3. Automatic acoustic tests of conference phones
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronikSammanfattning : 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.

4. Performance Evaluation of Digital Signa lProcessing Architectures Running an Acoustic Echo Cancellation Software
Master-uppsats, Umeå universitet/Institutionen för datavetenskapSammanfattning : TrueVoice is a speech enhancement software by Limes Audio AB. It improves the quality of the speech signal by using methods such as acoustic echo cancellation and noise reduction. The real time signal processing of TrueVoice puts some specic requirements on the hardware, which makes some processors more suitable than others to run the code. LÄS MER
5. Robust Echo-Cancellation for Simple VoIP-Applications in Embedded Systems
Master-uppsats, Linköpings universitet/KommunikationssystemSammanfattning : Voice over IP (VoIP) is the group of techniques for delivering voice communications over Internet Protocol (IP) networks. It has mainly served as the possible substitution for regular PSTN over the last decades, but has recently gained an increased interest in various areas such as alarm applications and customer service.
