Title of thesis: ROBUST VOICE MINING TECHNIQUES FOR TELEPHONE CONVERSATIONS Sandeep Manocha, Master of Science, 2006 Thesis directed by: Dr. Carol Y. Espy-Wilson Department of Electrical Engineering Voice mining involves speaker detection in a set of multi-speaker files. In published work, training data is used for constructing target speaker models. In this study, a new voice mining scenario w...

Security and Non-Repudiation for Voice-Over-IP Conversations

This thesis presents a concept to achieve non-repudiation for natural language conversations by electronically signing continuous, packet-based, digital voice communication (VoIP). Signing a VoIP-based conversation means to protect the integrity and authenticity of the bidirectional data stream and its temporal sequence which together establish the security context of the communication. The sol...

A secure archive for Voice-over-IP conversations

An efficient archive securing the integrity of VoIP-based two-party conversations is presented. The solution is based on chains of hashes and continuously chained electronic signatures. Security is concentrated in a single, efficient component, allowing for a detailed analysis.

Analysis of Voice Stress in Call Centers Conversations

This paper presents how voice stress is manifested in the acoustic and phonetic structure of the speech signal. Out of few thousand authentic Police 997 emergency phone calls, a few hundred were selected automatically according to their duration (dialogs shorter than 3-4 seconds were omitted). Finally, 45 speakers were chosen for acoustic evaluation, the basis for selection being a perceptual a...
