Abstract: Disclosed are techniques to automatically determine an audio path for a peripheral speaker. A wireless device uses particular wireless-communication methods or techniques, referred to as an audio path, to wirelessly communicate audio data to a speaker system for playback by a peripheral speaker. The device selects an audio path and attempts to send audio data representing known audio to the speaker system using the selected audio path. If a microphone of the device receives the known audio, then the device determines that the selected audio path is supported by the speaker system and thus can be used to communicate audio data to the peripheral speaker. However, if the microphone does not receive the known audio, then the device repeats the selecting of an audio path and attempting to send audio data to the speaker system using the newly selected audio path.

Abstract: The present invention provides a method, device and system to generate acoustic parameters in a text-to-speech system utilizing a neural network to generate a representation of a trajectory in an acoustic parameter space across a phonetic segment.

Abstract: A method and means for maintaining continuous bit synchronization of data transmitted from a remote unit through a base unit to a landline unit is disclosed. An input data stream at a first bit rate, such as digitized or encrypted speech, is interleaved with a plurality of signalling words, and transmitted over an RF channel at a second bit rate. The base site recovers the clock of the received data, strips off the signalling word, modifies the bit rate of the received data, and adjusts the recovered clock rate to provide an output data stream which is in bit synchronization with the input data stream and within a predetermined modem specification. The encrypted data is then sent over landlines to a decryption unit which requires bit synchronization.
