BACKGROUND/AIMS Frequency and amplitude perturbations are inherent in voice acoustic signals. The assessment of voice perturbation is influenced by several factors, including the type of recording equipment used and the measurement extraction algorithm applied. In the present study, perturbation measures provided by two computer systems (a purpose-built professional voice analysis apparatus and...

Voiceprint Recognition System also known as a Speaker Recognition System (SRS) is the best-known commercialized forms of voice Biometrics. Automated speaker recognition is the computing task of validating a user's claimed identity using characteristics extracted from their voices. In contrast to other biometric technologies which are mostly image based and require expensive proprietary hardware...

Throughout the history of communications systems, fault tolerance and other means to building resilient platforms were the exclusive and proprietary purview of Telecommunications Equipment Manufacturers (TEMs) and, more recently, Network Equipment Providers (NEPs). After the “dark ages” of telecom in the late 1990s, telecommunications system design began to experience a renaissance with ever-in...

Transcribing interview data is a time-consuming task that most qualitative researchers dislike. Transcribing is even more difficult for people with physical limitations because traditional transcribing requires manual dexterity and the ability to sit at a computer for long stretches of time. Researchers have begun to explore using an automated transcription process using digital recordings and ...

In the near future, 16 and 8 kbit/s tollor near-toll lowrate codecs are expected to be used together with 32 kbit/s digital circuit multiplication equipment, providing speech compression and digital speech interpolation. Additionally, a growing proportion of international calls originate from different digital cellular/satellite mobile (C/SM) systems. Knowledge of the end-to-end voice quality o...

My-Own-Voice is a service that provides a tool to end-users who want to have their voices synthesized by a high-quality commercial-grade Text-to-Speech system without the need to install, configure or manage speech-processing software and equipment. The system records and validates users’ utterances with Automatic Speech Recognition (ASR), to build an HMM or a Unit Selection synthetic voice. Al...

The age of speaker is a vital ingredient for many applications. Applications where access is based on age group can automatically use this simple system to identify the same. Access to machine or any equipment can also be authenticated with this system. Although there exist many difficulties when working with voice, it is a rich source of abundant information within it. With the help of acousti...

The voice calls over cellular networks are encrypted only over small sections of the full path, usually only between the Mobile Equipment and the Base Station/eNodeB. In this paper we propose a solution for highly secure end-to-end voice calls over the already existing voice call. As opposite to data channels, the normal audio channel provides low lag, low jitter and increased security due to t...
