Barbara J Wheatley, Charles T Hemphill, Thomas D Fisher, George R Doddington: System and method for time aligning speech. Robert L Troike, Richard L Donaldson, July 26, 1994: US05333275 (212 worldwide citation)

A method and system are provided for time aligning speech. Speech data is input representing speech signals from a speaker. An orthographic transcription is input including a plurality of words transcribed from the speech signals. A sentence model is generated indicating a selected order of the word ...

Joseph Picone, Barbara J Wheatley: Voice log-in using spoken name input. Texas Instruments Incorporated, Robert L Troike, Leo N Heiting, Richard L Donaldson, March 8, 1994: US05293452 (181 worldwide citation)

A voice log-in system is based on a person's spoken name input only, using speaker-dependent acoustic name recognition models in a performing speaker-independent name recognition. In an enrollment phase, a dual pass endpointing procedure defines both the person's full name (broad endpoints), and the ...

Barbara J Wheatley, Joseph W Picone: Voice recognition of proper names using text-derived recognition models. Texas Instruments Incorporated, Pehr B Jansson, Richard L Donaldson, William E Hiller, May 18, 1993: US05212730 (81 worldwide citation)

A name recognition system (FIG. 1 )used to provide access to a database based on the voice recognition of a proper name spoken by a person who may not know the correct pronunciation of the name. During an enrollment phase (10), for each name-text entered (11) into a text database (12), text-derived ...

Abraham P Ittycheriah, Barbara J Wheatley: Method and system for preventing entry of confusingly similar phases in a voice recognition system vocabulary list. Texas Instruments Incorporated, Robert L Troike, Richard L Donaldson, September 19, 1995: US05452397 (59 worldwide citation)

A method and system prevent the entry of confusingly similar phrases (60) in a vocabulary list (10) of a speaker-dependent voice recognition system. The method first receives (20, 30, 50) and enrolls the phrase (60) for adding to vocabulary list (10). Next, probabilities (62) are assigned to all phr ...

This invention consists of three enhancements to HMM-based automatic language identification systems. The three enhancements are: (i) language-discriminant acoustic model training and recognition, (ii) an acoustic model pruning procedure that picks only those phonetic models which are considered use ...

The memory and data management requirements for text independent speaker dependent recognition are drastically reduced by using a novel approach that eliminates the need for separate acoustic recognition models for each speaker. This is achieved by using speaker independent recognition models at the ...

Kazuhiro Kondo, Ikuo Kudo, Yu Hung Kao, Barbara J Wheatley: Speech recognition using clustered between word and/or phrase coarticulation. Texas Instruments Incorporated, Robert L Troike, Wade James Brady III, Richard L Donaldson, October 6, 1998: US05819221 (25 worldwide citation)

Improved speech recognition is achieved according to the present invention by use of between word and/or between phrase coarticulation. The increase in the number of phonetic models required to model this additional vocabulary is reduced by clustering 19, 20 the inter-word/phrase models and grammar ...
