Title: Method for segmenting voice
Inventor: KAMEI SHOICHI
IPC: G10L25/18
Filed: 1989-09-19
Abstract: PURPOSE:To reduce the influence of noise and to attain proper voice segmentation by setting up the threshold of voice segmentation based upon the average power of a band having a small band spectral power of peripheral noise. CONSTITUTION:The frequency of peripheral noise inputted from a microphone is analyzed by the number of bands determined in a frequency analyzing part 1. A segmenting band selecting part 2 selects a band whose difference from the maximum amplitude value is more than a fixed value as the band effective for voice segmentation out of respective band amplitude values. A threshold setting part 3 calculates the average value of the amplitude values of segmenting bands and sets up (n) times the average value as the threshold. After similarly analyzing voice inputted from the microphone, a voice segmenting part 4 calculates the average value of the amplitude values of the band selected by the selection part 2, and when the section in which the average value is more than the threshold is continued for a fixed time width or more, the section is segmented as a voice section. Thus, noise can easily be discriminated from voice and proper voice segmentation can be executed.

Title: Carrier phase controlling device
Inventor: KOKURIYOU GAROU
IPC: H04L27/38
Filed: 1983-12-28
Abstract: PURPOSE:To obtain a correction signal in few errors and to shorten a drawing time by adding a predetermined value to a phase difference signal when the value of the phase difference signal exceeds a specified value. CONSTITUTION:When the value of a phase difference signal is small and phase rotation is less than theta1, magnitude of sin(thetai-theta) and (thetai-theta) can be regarded as nearly equal, and accordingly, the device makes normal drawing action. However, when phase difference becomes larger, difference between sin(thetai-theta) and (thetai-theta) becomes gradually larger. When phase rotation becomes more than theta1, and the magnitude of the phase difference signal exceeds ref, a comparator circuit 6 generates an output signal and makes a switching circuit 7 on, and accordingly, a specified value (a) is added to the phase difference signal sin(thetai-theta) by an adder circuit 8. Consequently, the magnitude of the phase difference signal sin(thetai-theta) can be brought near to a target value (thetai-theta). Accordingly, a correction signal close to the target value is obtained and quick drawing can be obtained.
