Fusion Multistyle Training for Speaker Identification of Disguised Speech

Swati Prasad, Ramjee Prasad

Wireless Personal Communications > 2019 > 104 > 3 > 895-905

Determining the speaker of a given speech utterance from a group of people is referred to as speaker identification. When voice disguising is done by a person, which is commonly seen in crime scenes, a mismatch between the training and the test speech data occurs, referred to as mismatched problem. It markedly decreases the performance of the speaker identification system. To address this mismatched...

A Comprehensive Study of the Impact of Beacon Order and Superframe Order Values on Quality of Service in Multi-hop Wireless Networks on IEEE 802.15.4

Vjekoslav-Leonard Prčić, Damir Kalpić, Dina Šimunić, Ramjee Prasad

Wireless Personal Communications > 2019 > 104 > 1 > 373-385

The beacon order and Superframe order parameter values, as defined by the IEEE 802.15.4 standard specification, constrain the number of data packets that can be transmitted through a network in a given period by inferring the length of the network’s active and inactive periods. Choosing a specific value of either parameter can have significant impact on various quality of service measurements. This...
