This invention relates to a method and apparatus for recognizing a script written character. The character is entered using character entering device and digitised by appropriate device. The digitised character is then stored in, for example, a memory. Codes representing topological, vector dimension features and the microfeatures of the character are extracted from the character, then the features of the character are compared with a set of reference features corresponding thereto stored in a m...

A method and apparatus for inputting data to an active application program running on a computer system includes the steps of displaying the image of a recognition keypad on a screen of the computer system, the keypad being adapted to receive user inputs; analyzing the user inputs to the recognition keypad; and inputting data to an application program running on the computer system based upon the analysis of the user inputs. The recognition keypad includes at least one button and a recognition a...

In a switching system for connecting a call between a calling station and a called station, a system and method of voice recognition using a concentrated or distributed multiplicity of voice recognition and other resources with a facility for selecting an initial resource on the calling station going off-hook by accessing a demographic database and a biometric database using common channel signaling and selecting a prompt to be delivered to the caller from a multiplicity of preselected prompts a...

Input values are digitally represented and the bits used to address memories. A composite (e.g. the sum) of the memory outputs is formed, and update control is used during "learning" to modify the memory contents. The digital representation is formed by an encoder which encodes input values using a redundant code, which preferably has a Hamming distance to signal distance relationship which has a relatively steep initial slope and is closer to being monotonic than is the relationship for a simpl...

A speech recognition feature extractor for extracting speech features from a speech signal, comprising: a time-to-frequency domain transformer (FFT) for generating spectral magnitude values in the frequency domain from the speech signal; a frequency domain filtering block (Mel) for generating a sub-band value relating to spectral magnitude values of a certain frequency sub-band; a compression block (LOG) for compressing said sub-band values; a transformation block (DCT) for obtaining a set of de...

The present invention relates to a system and a method for recognizing a prescribed object, having a storage device for storing attribute information relating to the prescribed object, detecting means for detecting attributes in a detection range and for outputting corresponding detection information, first processing means for processing, in parallel and separately for each possible attribute type, the detection information for the detection means by using the attribute information from the sto...

This invention relates to an improved method and apparatus for speaker recognition. In this invention, prior to comparing feature vectors derived from speech with a stored reference model the feature vectors are processed by applying a speaker dependent transform which matches the characteristics of a particular speaker's vocal tract. Features derived from speech which has very dissimilar characteristics to those of the speaker on which the transform is dependent may be severely distorted by the...

Pattern recognition apparatus uses a recognition processor for processing an input signal to indicate its similarity to allowed sequences of reference patterns to be recognised. A speech recognition processor includes a classification arrangement to identify a sequence of patterns corresponding to said input signal and for repeatedly partitioning the input signal into a speech-containing portion and, preceding and/or following said speech-containing portion, noise or silence portions. A noise mo...

In a band for recognition, the present band for recognition comprises a flat plate shape display portion (2), a band portion (3) where multiple fixing holes (3a) are perforated, and a sealing portion (4), this sealing portion (4) including a male engagement portion (6) and a female engagement portion (7) arranged via a hinge portion (8), moreover, both engagement portion (6, 7) forming cutting rings (6c, 6d, 7a, 7b) around thin sheet portions (6a, 7c), and the biding force of the sealing portion...

A method of speech recognition includes recognizing a first utterance, recognizing a second utterance having information that is related to the first utterance, and determining the most probable first and second utterances based on stored information about valid relationships between possible first and second utterances. The most probable second utterance contains information that is semantically related to the most probable first utterance. The recognized first utterance may be recognized conti...
