Speaker Dependent Voice Recognition with Word-Tense Association and Part-of-Speech Tagging
… Research has been conducted on speech recognition and Speaker Recognition over the past few decades. Speaker recognition deals with identifying the speaker from multiple speakers and the ability to filter out the voice of an individual from the background for computational …

A voice interface for VTLS
The objective of this study was to develop a voice interface for the on-line catalog of VTLS. Three major components of the system, namely, voice recognition system, text-to-speech synthesizer, and screen review program, were identified. These components were selected after a comparative study of …

An investigation and evaluation into the 'usibility' of human-computer interfaces using a typical CAD system
… relating to the humancomputer interface namely, voice recognition, tools and techniques for evaluation, and user and interface modelling. An investigation into the implementation of voice recognition technologies examines how voice recognisers may be evaluated in commercial software. A prototype …

Dialects, Sex-specificity, and Individual Recognition in the Vocal Repertoire of the Puerto Rican Parrot (Amazona vittata)
… were used to determine the feasibility of vocal recognition of individuals. These methods included: bird-call pairing, sonagraphic analysis, and linear predictive coding. Sonagraphic analyses in combination with linear predictive coding techniques show the most promise as tools in voice …

Untersuchung zur Stimmerkennung bei aphasischen und nicht-aphasischen Patienten
… people by their faces as well as by their voices. Our ability to recognise speakers by their voice is certainly manifest in a lot of everyday situations. We can easily identify our partner speaking in another room or the voice of our neighbour sitting behind his hedge. Previous (fMRI-, …

Voice Authenticationa Study Of Polynomial Representation Of Speech Signals
A subset of speech recognition is the use of speech recognition techniques for voice authentication. Voice authentication is an alternative security application to the other biometric security measures such as the use of fingerprints or iris scans. Voice authentication has advantages over the other …

The role of context in infant preference for father's voice
… whether infants prefer their fathers’ voices over an unfamiliar male voice within the context of normal father-infant interaction, i.e., infant-directed (ID) speech. Twenty Caucasian male and female four-month-olds were tested in a visual-fixation preference procedure. Attentional …

LUI : a scalable, multimodal gesture- and voice-interface for large displays
… user interfaces that leverage gesture and voice recognition in addition to existing controller inputs. However, the state-of-the-art interfaces are quite rudimentary and not widely accessible for the user. Such interfaces require significant amount of sensors, extensive calibration, and/or …

Fluency and controlled-operant training methods
… Responses were made orally with the use of voice recognition software. One training method presented 50 stimuli on a computer monitor at a time (No ITIs). The other two methods (0s and 1.5s ITIs) presented stimuli separately on the monitor using discrete trials. Inter trial intervals were …

Active Mobile Interface for smart health
… The widespread availability of touch screens and voice recognition software has made it possible to execute commands in many different ways, especially on mobile computing devices. While this has made it possible to get work done with the minimum of physical exertion, the consequent sedentary life …

Understanding the landscape of adversarial robustness
… computer vision, natural language processing and voice recognition, state-of-the-art models are pervasively vulnerable to adversarial examples. Adversarial examples are inputs that have been slightly perturbed--such that the semantic content is the same--as to cause malicious behavior in a …

Robust Unconstrained Face Detection and Lip Localization Using Gabor Filters
Automatic speech recognition (ASR) is a well-researched field of study aimed at augmenting the man-machine interface through interpretation of the spoken word. From in-car voice recognition systems to automated telephone directories, automatic speech recognition technology is becoming increasingly …

Voice-interactive computer graphics and games
The art and science of speech recognition have been advanced to the state where it is now possible to communicate reliably with a computer by speaking to it in a disciplined manner using a vocabulary of moderate size. There are many applications of speech recognition technology in …
