Inventor: MILLER KEVIN D
IPC: G01S13/75
Filed: 1993-01-22
Abstract: A transponder for use in an object identification system including an interrogator which transmits a continuous interrogation signal and detects a responsive identification signal transmitted by the transponder. The transponder receives and detects the interrogation signal and, in response to receipt of the interrogation signal, produces a repeating identification signal having a fixed number of binary bits consisting of an identification data portion of a specified number of consecutive bits less than one half of the fixed number of bits, and a synchronization pattern of consecutive bits consisting of first, second and third bits of alternating binary values, a consecutive sequence of a plurality of bits which are all of the same binary value as the second bit, and a single bit of the same binary value as the first and third bits. The identification signal is modulated onto a carrier signal and transmitted. Preferably, the first, second and third bits and the sequence of a plurality of bits constitute one half of the fixed number of binary bits of the identification signal, with the binary value of the first bit being a binary 1.

Abstract: Method for speech signal synthesis by means of time concatenation of waveforms representing elementary units of speech signal, in which: at least the waveforms associated to voiced sounds are subdivided into a plurality of intervals, corresponding to the responses of the vocal duct to a series of excitation impulses of the vocal cords, synchronous with the fundamental frequency of the signal; each interval is subjected to a weighting; the signals resulting from the weighting are replaced with a replica thereof shifted in time by an amount that depends on a prosodic information; and the synthesis is carried out by overlapping and adding the shifted signals. In each interval of original signal to be reproduced in synthesis, an unchanging part is identified, which contains the fundamental information and which is reproduced unaltered in the synthesized signal, and the operations of weighting, overlapping and adding involve only the remaining part of the interval.
