Patent number: 10119286Abstract: A wave propagation apparatus. The apparatus includes a container enclosing a base layer/liquid and an overlying layer/liquid separated from each other. Above the overlying layer is a driver sprocket and a driven sprocket, which rotate about their respective central shafts, which are fixed across a width of the container. A closed chain loop is disposed around the sprockets, with a plurality of paddles secured thereto at a spaced distance away from each other. The chain rotates about the sprockets as they rotate about the central shafts. The driver sprocket rotates via a motor, which is controlled by a controller and powered by a power source. The paddles travel through the overlying layer but not through the base layer, thus displacing the fluid in the overlying layer and causing a dragging wave to appear in the base layer, due to the surface friction between the base layer and the overlying layer.Type: GrantFiled: May 3, 2018Date of Patent: November 6, 2018Assignee: The Florida State University Research Foundation, Inc.Inventor: Philip Gleason

Patent number: 8099281Abstract: A device and related methods for word-sense disambiguation during a text-to-speech conversion are provided. The device, for use with a computer-based system capable of converting text data to synthesized speech, includes an identification module for identifying a homograph contained in the text data. The device also includes an assignment module for assigning a pronunciation to the homograph using a statistical test constructed from a recursive partitioning of training samples, each training sample being a word string containing the homograph. The recursive partitioning is based on determining for each training sample an order and a distance of each word indicator relative to the homograph in the training sample. An absence of one of the word indicators in a training sample is treated as equivalent to the absent word indicator being more than a predefined distance from the homograph.Type: GrantFiled: June 6, 2005Date of Patent: January 17, 2012Assignee: Nunance Communications, Inc.Inventor: Philip Gleason

Patent number: 7853452Abstract: A method, a system, and an apparatus for identifying and correcting sources of problems in synthesized speech which is generated using a concatenative text-to-speech (CTTS) technique. The method can include the step of displaying a waveform corresponding to synthesized speech generated from concatenated phonetic units. The synthesized speech can be generated from text input received from a user. The method further can include the step of displaying parameters corresponding to at least one of the phonetic units. The method can include the step of displaying the original recordings containing selected phonetic units. An editing input can be received from the user and the parameters can be adjusted in accordance with the editing input.Type: GrantFiled: December 3, 2008Date of Patent: December 14, 2010Assignee: Nuance Communications, Inc.Inventors: Philip Gleason, Maria E. Smith, Mahesh Viswanathan, Jie Zeng

Patent number: 7464065Abstract: A computerized method (300) and software product (200) is provided for querying and modifying a Multi-Level Data Structure (106) stored in a Text-to-Speech (100) engine of a data processing system having a Central Processing Unit (202), a processing system memory (203), and an operating system (201), using an application program written in an interpretive programming language. The method includes the steps of initializing (302) by means of the CPU implementing a set of commands, a data processing environment for processing the application program, processing (306) the application program, where the processing includes identifying a marked command that encapsulates a DPMS program, and upon identifying a marked command, operating (318) on the MLDS using a DPMS interpreter for producing a result from the MLDS, the result available to the application program during execution of the application program.Type: GrantFiled: November 21, 2005Date of Patent: December 9, 2008Assignee: International Business Machines CorporationInventors: Philip Gleason, Steven M.

Patent number: 7280967Abstract: A method of filtering phonetic units to be used within a concatenative text-to-speech (CTTS) voice. Initially, a normality threshold can be established. At least one phonetic unit that has been automatically extracted from a speech corpus in order to construct the CTTS voice can be received. An abnormality index can be calculated for the phonetic unit. Then, the abnormality index can be compared to the established normality threshold. If the abnormality index exceeds the normality threshold, the phonetic unit can be marked as a suspect phonetic unit. If the abnormality index does not exceed the normality threshold, the phonetic unit can be marked as a verified phonetic unit. The concatenative text-to-speech voice can be built using the verified phonetic units.Type: GrantFiled: July 30, 2003Date of Patent: October 9, 2007Assignee: International Business Machines CorporationInventors: Philip Gleason, Maria E.

Patent number: 6829577Abstract: A method for producing vowel sounds in a waveform generator using non-stationary additive noise (NSAN) can include computing a frequency spectrum for a selected group of pitch pulses in a recorded sample of a spoken vowel; identifying a set of formant values in the computed frequency spectrum and creating an all-pole filter for the set of identified formant values; populating a zero-padded matrix with the selected group of pitch pulses and applying the all-pole filter to the matrix, the application of the filter producing a set of NSAN vectors; synthesizing a vowel sound in the waveform generator, the synthesis producing a further group of pitch pulses; and, adding the NSAN vectors to the further group of pitch pulses.Type: GrantFiled: November 3, 2000Date of Patent: December 7, 2004Assignee: International Business Machines CorporationInventor: Philip Gleason
