摘要： An optical disk reproducing apparatus of the type in which a tracking control is performed by projecting a controlling laser beam to the center of each of a plurality of V grooves formed on an optical disk and using far-field images of light beams reflected from the optical disk and the signals recorded on the adjacent slopes of the V groove are read by respectively projecting two reproducing laser beams to the slopes. To remove the low-frequency components of the signals on the slopes entering a tracking error signal, the low-frequency components are extracted from the two reproduced signals by low-pass filters and the difference therebetween is generated as a correction signal which in turn is subtracted from the tracking error signal, thereby improving the accuracy of the tracking control.

摘要： In an optical disk having grooves, pits representing reference signals in header regions of the grooves are disposed to be spaced apart from each other in a longitudinal direction of the groove to suppress undesirable interference or crosstalk of the reference signals in adjacent V-grooves. In the reproduction of such reference signals, two laser beam spots are respectively irradiated on the first and second oblique surface tracks in the V-groove. Two electric signals made by detecting the light reflected from the spots are examined to determine whether they are in coincidence. When coincidence is confirmed, the signals are used as valid reference signals.

摘要： A voice recognition apparatus is provided which includes a first detection circuit for receiving an electric signal corresponding to voice. The first detection circuit detects a voice termination point representing a time at which the input of the electric signal corresponding to the voice is terminated based on the electric signal. The apparatus further includes a second detection circuit for determining a speech period, the speech period being a period in which the voice is uttered within a whole period in which the voice is input, based on the electric signal. In addition, the apparatus includes a feature amount extracting circuit for producing a feature amount vector, on the basis of a part of the electric signal corresponding to the speech period. A memory is provided for storing feature amount vectors for a plurality of voice candidates which are previously generated. The apparatus further includes a circuit for recognizing the input voice, by comparing the feature amount vector from the feature amount extracting circuit with each of the feature amount vectors of the plurality of voice candidates stored in the memory. The speech period is determined by a detection of a speech period start point representing a time at which an utterance is started and a detection of a speech period termination point representing a time at which the utterance is terminated.
