1. Towards a Nuanced Evaluation of Voice Activity Detection Systems : An Examination of Metrics, Sampling Rates and Noise with Deep Learning
Master-uppsats, Linköpings universitet/Institutionen för datavetenskapSammanfattning : Recently, Deep Learning has revolutionized many fields, where one such area is Voice Activity Detection (VAD). This is of great interest to sectors of society concerned with detecting speech in sound signals. One such sector is the police, where criminal investigations regularly involve analysis of audio material. LÄS MER
2. Evaluation of the Perceived Speech Quality for G729D and Opus : With Different Network Scenarios and an Implemented VoIP Application
Master-uppsats, Linköpings universitet/InformationskodningSammanfattning : Communication has always been a vital part of our society, and day-to-day communication is increasingly becoming more digital. VoIP (voice over IP) is used for real-time communication, and to be able to send the information over the internet must the speech be compressed to lower the number of bits needed for transmission.

3. An Exploratory Study of Simple Fall and Activity Recognition Using mmWave
Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för datavetenskapSammanfattning : Background. As smart appliances become more attractive, the demand from public consumers grows, and producers are in search of innovative technologies that may aid in the creation of smart homes. Current products may use screens and buttons, voice commands and motion detection to create an interactive experience for consumers. LÄS MER
4. Robust Speech Activity Detection and Direction of Arrival Using Convolutional Neural Networks
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Social robots are becoming more and more common in our everyday lives. In the field of conversational robotics, the development goes towards socially engaging robots with humanlike conversation. This project looked into one of the technical aspects when recognizing speech, videlicet speech activity detection (SAD). LÄS MER
5. 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
