3. Performance Evaluation of Digital Signa lProcessing Architectures Running an Acoustic Echo Cancellation SoftwareMaster-uppsats, Umeå universitet/Institutionen för datavetenskap
Sammanfattning : 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
- Master-uppsats, Linköpings universitet/Kommunikationssystem
Sammanfattning : 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.
