  • Patent number: 8694323
    Abstract: The present invention provides a technique, by speech input, to specify a location, even when a name or the like of the location is not accurately known, while driving. An in-vehicle apparatus mounted in a vehicle has a speech recognition function, and stores information shown on a signboard and a noun substitute in storage. If speech inputted from a speech input device includes a noun substitute and further includes at least a part of the information shown on the signboard, a response is decided according to the information shown on the signboard, and the decided response is outputted from an output device.

  • Patent number: 5717818
    Abstract: The speed of an input speech is changed without any change of the pitch of the input speech. Raw data of a speech are stored so that the speed of the speech can be modulated continuously on the basis of the raw data of the speech. In the speech speed conversion method, a speech speed conversion process for the input speech is carried out in a period designated when speech speed conversion is needed, which the speech speed conversion is not carried out in the other period.

  • Patent number: 5715412
    Abstract: The present invention relates to a method of generating sounds by a graphical user interface (GUI) used on information processing apparatuses and computers and, more particularly, to a method of acoustically expressing image information to enable visually disabled people having difficulty in using GUI to operate apparatuses with GUI, and an apparatus for carrying out the method. A specific sound is assigned before hand to an object displayed in a drawing space on a display screen or the like, and the object is expressed acoustically by generating the sound by a sound generating device for a period of time corresponding to the length of the outline of the object, the travel of the object or the ratio of change in size of the object.

  • Patent number: 5675632
    Abstract: A telephone exchange enables subscribers to use voice dialing more easily with existing telephone systems. The voice dialing does not require special input operations or preregistration of called parties. Rather, a subscriber can make a telephone call easily without having to perform multiple operations. The telephone exchange includes structure for discriminating dial pulse information, push-button tone information, and spoken information so that one or more of these types of information can be input by a caller to achieve connection to the called party.

  • Patent number: 5185848
    Abstract: A noise reduction system used for transmission and/or recognition of speech includes a speech analyzer for analyzing a noisy speech input signal thereby converting the speech signal into feature vectors such as autocorrelation coefficients, and a neural network for receiving the feature vectors of the noisy speech signal as its input. The neural network extracts from a codebook an index of prototype vectors corresponding to a noise-free equivalent to the noisy speech input signal. Feature vectors of speech are read out from the codebook on the basis of the index delivered as an output from the neural network, thereby causing the speech input to be reproduced on the basis of the feature vectors of speech read out from the codebook.

  • Patent number: 4998280
    Abstract: A speech recognition apparatus including a memory for storing with respect to each feature specific to a particular phoneme a name of a process and a procedure of the process which is performed in order to search whether the presence of a feature specific to a certain type of speech is included in a feature vector series, and for storing a table in which the names of the processes in a performed for all the categories of speech to be recognized. The information stored in the memory is used to discriminate between two categories and provides ways for interpreting the results of the process.

  • Patent number: 4718095
    Abstract: A speech recognition method makes it possible to improve the accuracy of recognition of input speech and is capable of operating on a real time basis. This is accomplished by generating from the input speech signal a difference signal which indicates whether the speech power of the input speech is increasing or decreasing for each frame. The similarity between the input speech and a standard pattern is then calculated for each frame, and this is then followed by correcting the similarity calculation on the basis of the generated difference signal and a difference signal relating to the standard pattern obtained from storage. The matching of the input speech and the standard pattern is then effected by using the corrected similarity, and the input speech is then recognized from the result of this matching. Thus, a spectrum matching distance weighted by power information of speech can be obtained in real time.

  • Patent number: 4426551
    Abstract: Speech sound recognition is made using a reduced number of speech parameter elements, e.g., five correlation coefficients rather than sixteen spectral coefficients. The five correlation coefficients are derived from comparison of the spectral coefficients of unknown or standard sounds against the spectral coefficients of five highly-separable vowel-like sounds. Then, unknown-sound correlation coefficients are compared with standard-sound coefficients for recognition.

  • Patent number: 4401849
    Abstract: Speech signal presence is decided if total signal power is above a first threshold, and if either low or high frequency components exceed thresholds as a large fraction of the total power. Total power is calculated as the zero-order auto-correlation coefficient, and fractional power of frequency components is calculated as the first-order partial auto-correlation coefficient.
