摘要:
A plurality of pitch period candidates are selected from a peak of correlation of a speech waveform in a current frame from which a pitch period is to be extracted, and a speech pitch is selected from the candidates by referring to a guide index which is precalculated based on pitch periods extracted in past frames. The guide index is an average of the pitch periods in the past frames.

A method and apparatus for speech signal detection and classification in which a partial auto-correlation and residual power analyzation circuit extracts a normalized first-order partial auto-correlation coefficient and K.sub.1 a normalized zero-order residual power E.sub.N from an input signal, and a sound source analyzation circuit extracts a normalized residual correlation .phi. from the input signal, and in which on the basis of these extracted parameters, speech signals are detected, and, when so detected, the detected speech signals are classified into a voiced sound V, an unvoiced sound U and silence S. The classification of the respective voiced sound, unvoiced sound and silence is determined on the basis of preset threshold values that are mutually considered and which correspond to values of these extracted K.sub.1, E.sub.N and .phi. parameters for establishing boundary values for classifying the input signals into a voiced sound, an unvoiced sound or silence.

An instruction acceptance program is provided which is capable of saving time and labor required if a user has to choose a driver individually when choosing and executing either faxing or printing. This instruction acceptance program is used for allowing: a display control portion to display, in a display portion of a personal computer, a processing choice message which prompts the input of an instruction to execute either faxing or printing (Si); and an acceptance portion to accept the instruction to execute either faxing or printing.
摘要:
An echo suppressor for a communication system wherein a signal sent to a transmitting line is returned to a receiving line with some delay. The suppressor comprises an attenuator for attenuating the amplitude of a received speech signal. The transmitting speech signal amplitude level is compared to the amplitude of a receiving speech signal, and according to the result obtained, a signal for controlling the signal attenuation of the attenuator is generated. The delay time, until the attenuation control signal operates on the attenuator according to a change in the amplitude level of the receiving speech signal, is controlled. The controlled delay time is normally held at a predetermined maximum value, and is minimized when a change in amplitude of the receiving speech signal indicates a beginning of speech. Thus, an echo of the speech uttered by a near end user can be suppressed without impairing a beginning of the speech signal uttered by a far end user.

摘要:
A bidirectional communication system in which dial-up connection for transmitting communication data may be disconnected when not used, and may be insured to be reconnected when needed. Also, the system includes an arrangement in which availability of connection with dial-up may be notified/determined in advance. The bidirectional communication system includes a first communication station and one or more second communication stations, the second communication stations receiving information delivery service from the first communication station, and the second communication stations performing data communication with the first communication station by means of dial-up link. The first communication station includes: an assignor assigning to the second communication station a protocol identifier of a network layer; a connector/disconnector for connecting/disconnecting the communication link according to respectively the presence and absence of communication data from the second communication station; and a storage holding the protocol identifier of the network layer assigned to the second communication station during the information delivery service from the second communication station.
摘要:
In a subscriber information service system including a plurality of terminal equipment, and an information server for presenting personal information of a called subscriber to user at each of the terminal equipment, the information server being connected to the plurality of terminal equipment through a communication network, the information server has a subscriber information table consisting of a plurality of personal records each including a personal identifier assigned to a subscriber, a name of the subscriber, status information of the subscriber, and a name and an equipment address of the communication equipment which can be utilized by a user, and a facility of transmitting content data of the personal record of the specific subscriber registrated in the subscriber information table to each of the terminal equipment. Prior to the communication with the called subscriber, the user at each of the terminal equipment requests the information server to transmit the personal record of the called subscriber, and determines both the status of the called subscriber and the optimal communication equipment by referring to the contents of the personal record received from the information server.
摘要:
Clock timing is extracted from N level, multilevel codes of megabits per second data by determining a baud clock among the N-1 possible clocks synchronized to all the level cross points. A discriminator is used with a clock and if correct information is not obtained, the clock is changed.
