Abstract: The present invention relates to a speech recognition apparatus for recognizing speeches of a plurality of users with high accuracy. An adapting unit 12 detects a best transformation function for adapting an input speech to an acoustic model from at least one transformation function based on the transformation results which are obtained by transforming the input speech by at least one transformation function stored in a storing unit 13, and allocates the input speech to the best transformation function. Further, the adapting unit 12 updates the transformation function to which the new input speech is allocated by all the input speeches allocated to the transformation function. A selecting unit 14 selects the transformation function used for transforming the input speech from at least one transformation function stored in the storing unit 13. A transforming unit 5 transforms the input speech by the selected transformation function.

Abstract: The present invention relates to a voice recognition apparatus capable of easily registering a word which has not been registered. The registering of an unregistered word into a dictionary can be easily performed without causing a significant increase in the size of the dictionary. The clustering unit 29 detects a cluster (detected cluster) to which a new unregistered word is to be added as a new member, from existing clusters obtained by clustering unregistered words. The unregistered word is added as a new member to the detected cluster, and the cluster is divided depending on the members of the cluster such that unregistered words which are acoustically similar to each other belong to the same cluster. The maintenance unit 31 updates the word dictionary on the basis of the result of the clustering. The present invention may be applied to a robot including a voice recognition apparatus.

Abstract: According to the present invention network devices that can be controlled via a speech unit included in the network can send a device-document describing its functionality and its speech interface to said speech unit. The speech unit combines those documents to a general document that forms the basis to translate recognized user-commands into user-network-commands to control the connected network-devices. A device-document comprises at least the vocabulary and the commands associated therewith for the corresponding device. Furtheron, pronunciation, grammar for word sequences, rules for speech understanding and dialog can be contained in such documents as well as the same information for multiple languages or information for dynamic dialogs in speech understanding. It is possible that one device contains several documents and dynamically sends them to the speech unit in case they are needed.

Abstract: A robot performing a variety of actions is disclosed. The voice of a user picked up by a microphone is recognized by a voice recognizer. A gesture of the user picked up by a CCD is recognized by an image recognizer. A behavior decision unit decides the behavior to be taken by the robot based on the voice information provided by the voice recognizer and the image information provided by the image recognizer.

Abstract: A speech recognition apparatus in which the accuracy in speech recognition is improved as the resource is prevented from increasing. Such a word which is probable as the result of the speech recognition is selected on the basis of an acoustic score and a linguistic score, while word selection is also performed on the basis of a measure different from the acoustic score, such as the number of phonemes being small, a part of speech being a pre-set one, inclusion in the past results of speech recognition or the linguistic score being not less than a pre-set value. The words so selected are subjected to matching processing.

Abstract: In order to prevent degradation of speech recognition accuracy due to an unknown word, a dictionary database has stored therein a word dictionary in which are stored, in addition to words for the objects of speech recognition, suffixes, which are sound elements and a sound element sequence, which form the unknown word, for classifying the unknown word by the part of speech thereof. Based on such a word dictionary, a matching section connects the acoustic models of an sound model database, and calculates the score using the series of features output by a feature extraction section on the basis of the connected acoustic model. Then, the matching section selects a series of the words, which represents the speech recognition result, on the basis of the score.

Abstract: An extended-word selecting section calculates a score for a phoneme string formed of one or more phonemes, corresponding to the user's voice, and searches a large-vocabulary dictionary for a word having one or more phonemes equal to or similar to those of a phoneme string having a score equal to or higher than a predetermined value. A matching section calculates scores for the word searched for by the extended-word selecting section in addition to a word preliminarily selected by a preliminary word-selecting section. A control section determines a word string serving as the result of recognition of the voice.

Abstract: A robot performing a variety of actions is disclosed.

Abstract: A preliminary word-selecting section selects one or more words following words which have been obtained in a word string serving as a candidate for a result of voice recognition; and a matching section calculates acoustic or linguistic scores for the selected words, and forms a word string serving as a candidate for a result of voice recognition according to the scores. A control section generates word-connection relationships between words in the word string serving as a candidate for a result of voice recognition, sends them to a word-connection-information storage section, and stores them in it. A re-evaluation section corrects the word-connection relationships stored in the word-connection-information storage section 16, and the control section determines a word string serving as the result of voice recognition according to the corrected word-connection relationships.

Abstract: A method for recognizing speech is suggested.

Abstract: The invention relates to a method of producing a grinding roll in which a roll tire made from a highly wear-resistant bainitic cast material is applied to the basic roll body. In order to create a roll tire with particularly high reliability against fractures and with relatively high wear resistance and compression strength, the roll tire is produced from a ductile bainitic spheroidal graphite cast material having a breaking elongation of approximately 0.1 to 2.5% and a compression strength of approximately 1,000 to 1,800 Mpa.

Abstract: A roll mill has a fixed roll journalled in stationary fixed bearings and a floating roll journalled in movable bearings enabling the floating roll to be pressed against the fixed roll under high pressure. An adjustable spacing arrangement is provided between the two bearings to enable a gap of selected width to be formed between the rolls. The spacing arrangement includes a pair of shaft-like distance members received and guided in associated bores of the fixed bearings for movement therealong. Free ends of the distance members extend outward of their bores and engage the opposing floating bearings to adjust the positions of the rolls as they wear so as to maintain the selected gap width. The free ends are retractable into the bores to allow the bearings to abut one another and thereby optimize the wear life of the rolls.

Abstract: The invention relates to a roller mill with two rollers, a grinding gap formed thereby and a material inlet shaft the end walls of which bear on their lower ends carrier plates with replaceable sintered metal wear parts. Each wear part is formed by a plurality of small sintered metal plates of small area which are set close against one another like a mosaic and are individually screwed onto the carrier plate so that in case of wear only those small sintered metal plates which are actually worn can be replaced simply, quickly and economically.

Abstract: A bearing segment for a tiltable and rotatable sliding shoe comprises a base on which is supported a bearing pin having a radial ball and socket joint coupling the pin to the shoe. The ball and socket joint has an inner ring supported on the pin and an outer ring fixed to the shoe. The rings have confronting arcuate surfaces which permit limited relative spherical movement of the rings.

Abstract: The invention relates to a hydrodynamic bearing in which a pressure limiting valve is connected to the oil supply to a groove provided at the inlet zone of the bearing element. The oil pump thus can be of considerably smaller dimensions than heretofore, the energy consumption in operation is reduced, and the removal of heat is improved.

Abstract: A hydrodynamic bearing for supporting a rotary member has a bearing gap between the rotary member and the bearing and which is occupied by fluid. Hydrodynamic pressure in the gap is monitored by a sensor which is coupled to a starting aid that is responsive to variations in the hydrodynamic pressure to switch on and off a starting aid. Upon being switched on the starting aid is operable to deliver additional fluid to the bearing gap.

Abstract: A hydrostatic bearing the bearing surface of which contains several pressure pockets. A bore arranged symmetrically to the pressure pockets connects the latter with a pressure relief chamber and with a source of hydraulic pressure medium. A bearing such as this is characterized by its simple construction and by reliable hydraulic pressure relief for each bearing shoe.

Abstract: This invention relates to a hydrostatic bearing unit for rotating parts, and more especially to a radial bearing unit for heavy machine parts, such as drums, comprising a fixed base and a shoe which is mounted for limited gyration relative to the base and for hydraulic adjustment with respect to the rotating parts and which comprises a bearing surface fed with hydraulic carrier medium. The invention also relates to a hydrostatic bearing assembly comprising several such bearing units.
