Abstract: Exemplary embodiments of the invention enhance the recognition ability by optimizing the distribution numbers for respective states that constitute an HMM (for example, a syllable HMM).

Abstract: To provide an acoustic model which can absorb the fluctuation of a phonemic environment in an interval longer than a syllable, with the number of parameters of the acoustic model suppressed to be small, a phoneme-connected syllable HMM/syllable-connected HMM set is generated in such a way that a phoneme-connected syllable HMM set corresponding to individual syllables is generated by combining phoneme HMMs. A preliminary experiment is conducted using the phoneme-connected syllable HMM set and training speech data. Any misrecognized syllable and the preceding syllable of the misrecognized syllable are checked using results of a preliminary experiment syllable label data. The combination between a correct answer syllable for the misrecognized syllable and the preceding syllable of the misrecognized syllable is extracted as a syllable connection. A syllable-connected HMM corresponding to this syllable connection is added into the phoneme-connected syllable HMM set.

Abstract: The invention provides an acoustic model creating method that can reduce the number of parameters and optimize the Gaussian distribution number for respective states constituting an HMM in order to create an HMM having high recognition ability. HMM sets in which the Gaussian distribution numbers of the respective states constituting the respective syllable HMMs are set from one to the maximum distribution number (the distribution number of which is 64) is trained using training speech data, and the respective states of the respective HMMs are viterbi-aligned with the training speech data corresponding to the HMMs using a syllable HMM set to the maximum distribution number among the trained syllable HMM sets. Then, a description length computing unit computes a description length for the respective states of the respective HMMs using the alignment data, and a state selecting unit selects a state having the distribution number the description length of which is minimum.

Abstract: An automotive door handle container which is formed by and on an escutcheon fixedly attached to a door panel, for normally containing a pivotable handle piece. The escutcheon is formed at a slightly lower level than the inside edge of the handle piece for covering a small idle gap between the handle piece and the escutcheon to prevent harmful physical damage to the operator's finger nail otherwise occurring during manual handling of the handle piece.

Abstract: A position coordinate input device including an input plate subjected, at a point, to an external force with a finger, etc. so as to input data of coordinates of the point into a computer and the like. The device further includes four elastic support members for supporting the input plate, a pair of two first detectors yielding outputs of temperature characteristics of a first sign and a pair of two second detectors yielding outputs of temperature characteristics of a second sign opposite to the first sign so as to enable accurate detection of the coordinates of the point of application of the external force in a simplified construction.

Abstract: A speaker diaphragm comprises a composite film prepared by combining a reinforcing material such as a mica, a needle or fiber filler, or talc, with a polybisphenol phthalate resin consisting of an aromatic dicarboxylic acid and a dihydric phenol.

Abstract: The invention resides in an outside door handle assembly which comprises a door handle pivotably mounted on a door of an automotive vehicle; and a door latch operating rod having an end portion which is pivotably attached to an extension of said door handle after assemblying thereto. A pair of finger projections are made integral with the door handle arm. There is provided a channel-shaped metal bracket fixedly attached to a door panel and pivotably mounting said finger projections. An inclined groove formed on each of the finger projections generally opening towards the two limbs of the bracket and adapted for receiving partially these limbs when said door handle arm has been brought into its upper service position, thereby torsional deflexion of the bracket as liably occuring during the door-opening operation being prevented effectively.

Abstract: The present invention discloses a gas combustion device with a safety device including a combustible gas sensor which consists of an oxygen concentration cell comprising a calcined solid ion conductive electrolyte material and porous electrodes attached to both the major surfaces of the electrolyte material. The safety valve is operated in response to both outputs from the combustible gas sensor and from a pilot burner sensor including a thermocouple or the like. When the carbon monoxide content is increased, the safety valve is automatically closed, thereby interrupting the supply of gas and consequently preventing carbon monoxide poisoning and/or gas explosion.
