Packet Voice Recovery Techniques for Real-time Internet Voice Communication
The Internet’s phenomenal growth, worldwide coverage and increasing data delivery capabilities have made possible its use as an alternative communications medium for real-time voice messages. In addition, using the Internet for voice communication circumvents the high costs of long-distance phone rates. However, the Internet is a relatively harsh environment for real-time voice communication. P...
متن کاملVoice Modification for Lip Synchronization, Voice Dubbing and Karaoke
The voice modification system studied in this paper allows to ’transplant’ selected voice characteristics (pitch, loudness, timing, and/or timbre) from a given ’donor’ utterance onto another (’patient’) utterance. Several potential applications exist for such a system, depending on the voice characteristics that are transplanted. The examples studied here are lip synchronization, voice dubbing ...
متن کاملDynamic priority protocols for packet voice
Since the reconstruction of continuous speech from voice packets is complicated by the variable delays of packets through the network, delay variability is an important measure of performance for voice packet networks. A dynamic priori@ protocol designed to minimize the Variability of packet delays is proposed. The protocol allows the priority of a packet to vary with time. Two examples of dyna...
متن کاملTransient QOS Guarantee for Packet Voice
The existing work has demonstrated that resource dimensioning based on steady-state performance analysis can not provide reliable QOS guarantee for packet voice applications. We propose a bandwidth and buuer dimensioning mechanism for support of voice connections in packet-switched networks, which can provide transient QOS guarantee for individual voice connections while keeping statistical mul...
متن کاملComparison of transmitter - based packet-loss recovery techniques for voice transmission
To facilitate real-time voice communication through the Internet, forward error correction (FEC) and multiple description coding (MDC) can be used as low-delay packet-loss recovery techniques. We use both a Gilbert channel model and data obtained from real IP connections to compare the rate-distortion performance of different variants of FEC and MDC. Using identical overall rates with stringent...
