Abstract: A modulation scheme (600) useful in a voice paging system in which both of two orthogonal modulation components (500 and 510) are used to carry two halves of a single voice message destined for a receiver, or two separate voice messages for a receiver. The single voice message is transmitted in half the time.

Abstract: A method for time-scale modification of speech using a modified version of the Waveform Similarity based Overlap-Add technique (WSOLA) comprises the steps of storing a portion of an input speech signal in a memory, analyzing the portion of the input speech signal providing an estimated pitch value (12), determining a segment size (14) in response to the estimated pitch value and time-scaling (18) the input speech signal for a given time-scaling factor and in response to the determined segment size.

Abstract: The present invention comprises a method for compressing a plurality of voice signals within a voice communication resource (see FIG. 6) having a given bandwidth within a voice communication system (100). The method comprises the steps of subchanneling the voice communication resource into a plurality of subchannels (441, 442, 443), placing a pair of the plurality of voice signals (401, 402) on a subchannel (441); modulating the pair of the plurality of voice signals (401, 402) about a pilot signal (581) within the subchannel (441) using single sideband modulation; and compressing the time of each of the voice signals (401, 402) within the plurality of subchannels (441, 442, 443), wherein these step provide a compressed voice signal.

Abstract: A method (100) of compressing a digital signal that is parametrically modeled and encoded includes the steps of storing (102) the digital signal in a memory in a plurality of frames having a plurality of parameters in each frame of the plurality of frames, wherein the digital signal was encoded at a higher rate and converting the digital signal to a lower rate by selecting (106) from each frame of the plurality of frames a subset of the plurality of parameters and discarding (108) the subset of the plurality of parameters within each frame of the plurality of frames.

Abstract: A method and apparatus for time-scale modification of speech using a modified version of the Waveform Similarity based Overlap-Add technique (WSOLA) comprises the steps of storing a portion of an input speech signal in a memory, analyzing the portion of the input speech signal to determined at least one filtered pitch value, calculating an estimated pitch value (12) from the at least one filtered pitch value, determining a segment size (14) in response to the estimated pitch value (12), the segment size (14) having a value greater than the estimated pitch value (12), and time-scale compressing (18) the input speech signal in response to the segment size determined.

Abstract: A method and apparatus is for use in a radio communication system (100) for delivering a message from a system controller (102) to a selective call device. In the system controller (102) the method includes the steps of generating a first message intended for the selective call device (106), changing a delivery state of the first message to undelivered after the first message has been transmitted at least once from the system controller (102), and storing the first message in the system controller (102) when the delivery state is changed to undelivered. In the selective call device the method includes the steps of determining that the first message is stored in the system controller (102) and presenting user with information which indicates that an undeliverable message is being stored by the system controller (102) in response to determining that the first message (102) is stored in the system controller (102).
