Patent number: 7606704Abstract: A non-intrusive speech quality assessment system. A method and apparatus for training a quality assessment tool in which a database comprising a plurality of samples, each with an associated mean opinion score, is divided into a plurality of distortion sets of samples according to a distortion criterion; and a distortion specific assessment handler for each distortion set is trained, such that a fit between a distortion specific quality measure generated from a distortion specific plurality of parameters for a sample and the mean opinion score associated with said sample is optimised. A method and apparatus for assessing speech quality in a telecommunications network in which a dominant distortion type is determined for a sample; a distortion specific plurality of parameters are combined to provide a distortion specific quality measure for each sample; and a quality measure is generated in dependence upon the distortion specific quality measure.Type: GrantFiled: January 14, 2004Date of Patent: October 20, 2009Assignee: Psytechnics LimitedInventors: Philip Gray, Ludovic Malfait

Publication number: 20060224387Abstract: Non-intrusive speech-quality assessment uses vocal-tract models, in particular for testing telecommunications systems and equipment. This process requires reduction of the speech stream under assessment into a set of parameters that are sensitive to the types of distortion to be assessed. Once parameterized, the data is used to generate a set of physiologically-based rules for error identification, using a parametric modeling of the shape of the vocal tract itself, by comparison between derived parameters and the output of models of physiologically realistic forms for the vocal tract, and the application of physical constraints on how these can change over time.Type: ApplicationFiled: December 30, 2005Publication date: October 5, 2006Applicant: British Telecommunications public limited companyInventors: Philip Gray, Michael Hollier

Patent number: 7050924Abstract: The perceptibility of degradations caused to signals transmitted over a transmission medium is measured by generating one or more predetermined transmission degradation conditions (et) and subjecting a test signal (St) to the transmission degradation conditions (et) in a network simulation device. The degree M(e) to which the or each transmission degradation condition (et) is perceptible to the human perceptual system is measured and a data set is generated and stored for converting one or more transmission degradation conditions (et) to respective values of perceptibility M(e). The data set may be a look-up table or an empirically determined formula. The data set may then be used on live traffic (S?), by identifying objectively measured transmission degradation conditions (e) in the received signal (S?) and retrieving from the data set in the data storage means (7) a value of perceptibility (M) associated with the transmission degradation conditions (e) so identified.Type: GrantFiled: May 25, 2001Date of Patent: May 23, 2006Assignee: British Telecommunications public limited companyInventors: Antony W Rix, Philip Gray, Richard J B Reynolds, Michael P Hollier

Patent number: 6797515Abstract: Methods of production of desired recombinant proteins, polypeptides and peptides are disclosed which utilize mammalian host cells engineered for autonomous and regulated growth in low cost protein/serum-free culture media. Preferred host cells express insulin or an insulin-like growth factor, and/or transferrin and are engineered so that addition of an inducer (e.g., ZnCl2+CdCl2) halts growth and simultaneously induces the expression of the desired recombinant protein, polypeptide or peptide.Type: GrantFiled: September 28, 2001Date of Patent: September 28, 2004Assignees: Unisearch Limited, Commonwealth Scientific and Industrial Research OrganisationInventors: Sybille Marie Hunt, Peter Philip Gray, Merilyn Joy Sleigh

Publication number: 20030092394Abstract: A method of testing the degree of degradation imposed on signals transmitted over a communications link from a transmitter to a receiver, comprises the steps of transmitting a predetermined test signal using spare capacity detected by a voice activity detector when no speech is to be transmitted over the communications link, comparing the test signal received by the receiver with the reference signal, and generating therefrom a measure of the degradation of signals caused by the communications link. Typically the test signal is longer than the speech gaps, so a part of the test signal in each such gap, the receiver assembling a complete version of the degraded test signal for comparison with the reference signal.Type: ApplicationFiled: November 6, 2002Publication date: May 15, 2003Inventors: Philip Gray, Michael P Hollier, Richard JB Reynolds, Antony W Rix

Patent number: 6035270Abstract: A speech signal is subjected imperfect to vocal tract analysis model and the output therefrom is analyzed by a neural network. The output from the neural network is compared with the parameters stored in the network definition function, to derive measurement of the quality of the speech signal supplied to the source. The network definition function is determined by applying to the trainable processing apparatus a distortion perception measure indicative of the extent to which a distortion would be perceptible to a human listener.Type: GrantFiled: February 3, 1998Date of Patent: March 7, 2000Assignee: British Telecommunications public limited companyInventors: Michael P Hollier, Philip J Sheppard, Philip Gray
