Abstract: A system and method for eliminating synchronization errors using speech recognition. Using separate audio and visual speech recognition techniques, the inventive system and method identifies visemes, or visual cues which are indicative of articulatory type, in the video content, and identifies phones and their articulatory types in the audio content. Once the two recognition techniques have been applied, the outputs are compared to determine the relative alignment and, if not aligned, a synchronization algorithm is applied to time-adjust one or both of the audio and the visual streams in order to achieve synchronization.

Abstract: A system and method for detecting the presence of a particular source of audible content using an automatic speech recognizer component which is trained to recognize specific non-speech sounds. Training of the automatic speech recognizer component is accomplished by providing an appropriate model to be recognized and by tuning the automatic speech recognizer to the sounds created by the desired stimulus. The automatic speech recognizer can additionally be provided with processing means for distinguishing the desired stimulus from an irrelevant or unwanted stimulus which may have acoustic signatures with a high degree of similarity to that of the desired stimulus. The invention can be implemented in a portable detector to allow detection of a specific acoustic source at any location.

Further, the invention relates to live attenuated recombinant bacteria carrying a heterologous gene and vaccines based thereon. Finally, the invention relates to methods for the preparation of such vaccines and bacteria.

Abstract: A method for designating a subvocabulary for speech recognition systems includes the steps of providing a vocabulary of words each having a flag with a first value, selecting words to be eliminated from the vocabulary, setting the flags of the selected words to a second value and processing speech based on words having the flag set to the first value. A program storage device readable by machine, tangibly embodying a program of instructions executable by the machine to perform method steps for disabling and enabling of subvocabularies in speech recognition systems, the method steps include providing a vocabulary of words each having a flag with a first value, selecting words to be eliminated from the vocabulary, setting the flags of the selected words to a second value and processing speech based on words having the flag set to the first value.

Abstract: A method and system for participating in and controlling a non-real-time voice conference. By recording a first participant's voice for playback to a second participant that is not connected at the same time as the first participant, a new type of voice conference is created.

Abstract: In accordance with the present invention, a method for increasing both dialect precision and usability in speech recognition and text-to-speech systems is described. The invention generates non-linear (i.e. encoded)baseform representations for words and phrases from a pronunciation lexicon. The baseform representations are encoded to incorporate both pronunciation variations and dialectal variations. The encoded baseform representations may be later expanded (i.e. decoded) into one or more linear dialect specific baseform representations, utilizing a set of dialect specific phonological rules. The method comprises the steps of: constructing an encoded pronunciation lexicon having a plurality of encoded and unencoded baseforms; inputting one or more user specified dialects; selecting dialect specific phonological rules from a rule set database; and decoding the encoded pronunciation lexicon using the dialect specific phonological rules to yield a dialect specific decoded pronunciation lexicon.

Abstract: A pharmaceutical formulation for stimulating growth of Gram-positive Bacilli and increasing the acidity in vagina comprises sucrose and/or maltose, optionally with other sugars, viscous base, and anti-fungal and/or anti-bacterial agents.

Abstract: A method and system are disclosed for reducing perplexity in a speech recognition system within a telephonic network based upon determined caller identity. In a speech recognition system which processes input frames of speech against stored templates representing speech, a core library of speech templates is created and stored representing a basic vocabulary of speech. Multiple caller-specific libraries of speech templates are also created and stored, each library containing speech templates which represent a specialized vocabulary and pronunciations for a specific geographic location and a particular individual. Additionally, the caller-specific libraries of speech templates are preferably processed to reflect the reduced bandwidth, transmission channel variations and other signal variations introduced into the system via a telephonic network.

Abstract: A method and system for reducing perplexity in a speech recognition system based upon determined geographic location. In a mobile speech recognition system which processes input frames of speech against stored templates representing speech, a core library of speech templates is created and stored representing a basic vocabulary of speech. Multiple location-specific libraries of speech templates are also created and stored, each library containing speech templates representing a specialized vocabulary for a specific geographic location. The geographic location of the mobile speech recognition system is then periodically determined utilizing a cellular telephone system, a geopositioning satellite system or other similar systems and a particular one of the location-specific libraries of speech templates is identified for the current location of the system.

Abstract: A continuous speech recognition system having a speech processor and a word recognition computer subsystem, characterized by an element for developing a graph for confluent links between confluent nodes; an element for developing a graph of boundary links between adjacent words; an element for storing an inventory of confluent links and boundary links as a coding inventory; an element for converting an unknown utterance into an encoded sequence of confluent links and boundary links corresponding to recognition sequences stored in the word recognition subsystem recognition vocabulary for speech recognition. The invention also includes a method for achieving continouous speech recognition by characterizing speech as a sequence of confluent links which are matched with candidate words. The invention also applies to isolated word speech recognition as with continuous speech recognition, except that in such case there are no boundary links.
