Abstract: A method and apparatus for accessing data stored in a local telephone terminal from a remote terminal and displaying or storing it on the remote terminal. An ADSI or JAVA script or readable message is sent to the local telephone terminal, providing it with instructions about how to transmit and translate the data for use by the remote terminal. The method allows for password protection of the date and non-ringing of the local telephone terminal.

Abstract: A telephone instrument creates spatially simulated sound signals from signals received from a telephone line. The received signals are directed to left and right channels. In each channel, the signals are processed via a direct path, an early reflection path including a finite impulse response filter and a reverberant decay path including all-pass filter. In each channel, the outputs from the three paths are summed with different weights.

Abstract: A speech bandwidth extension method and apparatus analyzes narrowband speech sampled at 8 kHz using LPC analysis to determine its spectral shape and inverse filtering to extract its excitation signal. The excitation signal is interpolated to a sampling rate of 16 kHz and analyzed for pitch control and power level. A white noise generated wideband signal is then filtered to provide a synthesized wideband excitation signal. The narrowband shape is determined and compared to templates in respective vector quantizer codebooks, to select respective highband shape and gain. The synthesized wideband excitation signal is then filtered to provide a highband signal which is, in turn, added to the narrowband signal, interpolated to the 16 kHz sample rate, to produce an artificial wideband signal. The apparatus may be implemented on a digital signal processor chip.
