The task of speaker verification, a subset of the general problem of speaker recognition is defined. The feature selection and pattern matching steps of the recognition procedure are examined. Speaker verification system design and performance are discussed, and databases for evaluating them are briefly considered. An example of a speaker verification system is described. An overview of industry research in this area is given. >read more

Speaker Recognition by Machines and Humans: A tutorial review
John H. L. Hansen,Taufiq Hasan +1 more
TL;DR: A comparative study of human versus machine speaker recognition is concluded, with an emphasis on prominent speaker-modeling techniques that have emerged in the last decade for automatic systems.

Cryptographic key generation from voice
TL;DR: The technique is sufficiently robust to enable the user to reliably regenerate the key by uttering her password again, and an empirical evaluation of this technique is described using 250 utterances recorded from 50 users.

Concatenated phoneme models for text-variable speaker recognition
Tomoko Matsui,Sadaoki Furui +1 more
TL;DR: Methods that create models to specify both speaker and phonetic information accurately by using only a small amount of training data for each speaker are investigated and supplementing these methods by adding a phoneme-independent speaker model to make up for the lack of speaker information.
PatentDOI
Speaker verification with cohort normalized scoring
TL;DR: In this paper, a facility is provided for allowing a caller to place a telephone call by uttering a label identifying a desired called destination and to charge the telephone call to a particular billing account by merely uttering the label identifying that account.

A tutorial on hidden Markov models and selected applications in speech recognition
TL;DR: In this paper, the authors provide an overview of the basic theory of hidden Markov models (HMMs) as originated by L.E. Baum and T. Petrie (1966) and give practical details on methods of implementation of the theory along with a description of selected applications of HMMs to distinct problems in speech recognition.

Dynamic programming algorithm optimization for spoken word recognition
TL;DR: This paper reports on an optimum dynamic progxamming (DP) based time-normalization algorithm for spoken word recognition, in which the warping function slope is restricted so as to improve discrimination between words in different categories.
Journal ArticleDOI
Minimum prediction residual principle applied to speech recognition
TL;DR: A computer system is described in which isolated words, spoken by a designated talker, are recognized through calculation of a minimum prediction residual through optimally registering the reference LPC onto the input autocorrelation coefficients using the dynamic programming algorithm.
Cepstrum analysis technique for automatic speaker verification
TL;DR: New techniques for automatic speaker verification using telephone speech based on a set of functions of time obtained from acoustic analysis of a fixed, sentence-long utterance using a new time warping method using a dynamic programming technique.

Cepstral analysis technique for automatic speaker verification
TL;DR: In this paper, a set of functions of time obtained from acoustic analysis of a fixed, sentence-long utterance are extracted by means of LPC analysis successively throughout an utterance to form time functions, and frequency response distortions introduced by transmission systems are removed.
