摘要： Several encoders perform a local decoding of a speech signal and extract excitation information and vocal tract information from a speech signal for an encoding operation. The transmission rate ratio between the excitation information and the vocal tract information are different for each encoder. An evaluation/selection unit evaluates the quality of decoded signals subjected to a local decoding in each of the encoders, determines the most suitable encoders from among the several encoders based on the result of the evaluation, and selects the most suitable encoder, thereby outputting the selection result as selection information. The decoder decodes a speech signal based on selection information, vocal tract information and excitation information. The evaluation/selection unit selects the output from the encoder in which the quality of a locally decoded signal is the most preferable. When vocal tract information changes little, the vocal tract information is not output, thereby allowing for increased quality of information. As much of the surplus of unused vocal tract information as possible is assigned to a residual signal. Thus, the quality of a decoded speech signal is improved.

摘要： Speech is data-compressed and coded for transmission using TDHC (Time Domain Harmonic Compression) for the voiced signal, and decimated sampling for the unvoiced signal. Features include voiced/unvoiced detection, pitch period detection, border detection, coding by ADPCM, and optimum quantization coding. Reception involves decoding and data-reconstruction.

摘要： Disclosed is a voice coding/decoding system having a transmitting part for transmitting a coded signal of an input voice signal at a bit rate lower than a predetermined transmission bit rate and a receiving part for receiving and decoding the coded signal transmitted from the transmission part. To enable the coding and transmitting of an input voice signal in an optimum state without passing through a buffer memory and without having a negative influence on the coder, the transmitting part provides coders for coding the input voice signal and groups of entropy coders. The inputs of the entropy coders in each group are connected to the output of one of the plurality of coders. The transmitting part further provides an evaluation part for evaluating the characteristics of the outputs of the coders and the entropy coders. The evaluation part extracts those entropy coders having output bit rates lower than the transmission bit rate and extracts, from the coders connected to the extracted entropy coders, a coder having the best output characteristic. Then, the evaluation part outputs a selecting signal indicating the combination of the selected coder and an entropy coder from the extracted entropy coders. The transmitting part further provides a selecting part for selecting, in response to the selecting signal, the codeword passed through the combination of the coder and the entropy coder to be transmitted.

摘要： A voice coding apparatus includes a pitch detecting circuit which detects a pitch period of a voice signal; a pitch waveform generating circuit which samples the voice signal for a plurality of pitches based on the pitch period detected by the pitch detecting circuit and which generates a waveform of one pitch from the waveform of the plurality of pitches; a band restriction circuit which restricts the frequency band of the one pitch waveform generated in the pitch waveform generating circuit; and a coding circuit for coding the voice waveform which is band restricted in the band restriction circuit. The sampling number of the waveform for a plurality of pitches and the restricted bandwidth can be changed in accordance with the amount of the pitch period extracted in the pitch detecting circuit. Further, the pitch detecting circuit is able to correctly detect the pitch period even when the pitch period is not a multiple of the sampling period.

摘要： A charging system for a legged mobile robot that facilitates positioning of a robot to be charged and does not put a load on the robot is provided. The charging system includes a battery 2, a power receiving connector 4 and a movable shutter member 5 capable of being opened and closed on a rear cover 3, which are provided on a robot 1, and a holder 21, a power supplying connector 22, a slide mechanism 23, a base plate 25, a charging power supply 26 and the like, which are provided on a charging station 20. The robot 1 performs a predetermined positioning on the base plate 25 and then moves the center of gravity rearward to connect the power receiving connector 4 to the power supplying connector 22. In this step, when the rear cover 3 of the robot 1 is guided by a first guide section 21a of the holder 21, the slide mechanism 23 allows the holder 21 to move horizontally. Thus, even if the robot 1 and the charging station 20 are slightly misaligned with each other, the robot 1 can be easily positioned correctly.
