The present invention relates to a markup language document stored on a computer-readable medium to provide interactive services and methods thereof. The markup language comprises a dialog element and a step element. The dialog element includes markup language elements in which each markup language element is identifiable by one or more markup tags. The step element is contained within the dialog element and defines a state within the dialog element. The step element includes a prompt element, a...

In a speech processing system, an optimal filter frequency is determined and used to filter an unfiltered signal. The optimum filter is chosen by passing the largest voice area greater than 50 ms through multiple filters. The average energy output for each filter and differences between the filter averages (DeltaEnergy) are calculated. The first peak in DeltaEnergy above the average DeltaEnergy determines the optimal filter for filtering the signal. The filtered signal is divided into segments a...

A system allows a user to use conversational commands to control the recording of video programming. In some embodiments of the present invention, these natural language commands may be also utilized to manage a video library or to manage a schedule for video recordings. The video recording device may be an analog or digital system.

A time-axis compression/expansion system compresses or expands a multichannel signal at a specified compression/expansion rate. Waveform segments are sequentially cut out from each channel signal. A cutting starting point of a leading end portion of a waveform segment following each preceding waveform segment of the cut out waveform segments is determined commonly between the channel signals, based on two portions of a waveform of a synthesized signal formed by synthesizing the channel signals w...

Method for assignment of a selectable option to an actuating means in which a voice-aided control device is activated in order to assign to the actuating means a selectable option for a selection command. In order to assist a user in the selection of an option to be assigned to the actuating means, the invention provides that after activation of the voice-aided control device, the selectable options which are currently available can be announced.

There is provided a speech decoder comprising a means for generating an excitation signal and a means for performing harmonic analysis and synthesis on the excitation signal in order to generate a smooth, periodic speech signal. The speech decoder further comprises a mixing means for mixing the excitation signal with the smooth, periodic signal and a synthesizing means for synthesizing the modified excitation signal into a speech signal that can be played to a user through a listening means. The...

An application (50) utilizing a speech recognition interface (10) employs the use of verbal proxies to accomplish dynamic vocabulary updates. One or more proxies used by the application (50) are defined (60) and added to the vocabulary (38) of the speech recognition interface (10). Upon the speech recognition interface (10) receiving a speech signal (14) representative of a command containing a defined proxy, the recognized speech is converted to text by the speech recognition interface (66, 68)...

A speaker verification system using the voice of a user uttering a continuous, random length digit string is provided. The speaker verification system includes a random digit generator for generating a continuous, random length digit string; a user interface for providing the continuous, random length digit string; a feature extractor for extracting voice features from the user's voice uttering the continuous, random length digit string; a digit voice verification unit for comparing the voice fe...

A method for variably controlling the number of packets constituting a voice data frame according to the traffic condition to secure the real-time transmission of voice data. The method comprises the steps of: upon the receipt of a voice data frame, storing a stamp time of the voice data frame and the number of packets constituting the voice data frame; removing an RTP header included in the voice data frame and storing the RTP header-removed voice data in a receiving buffer; calculating an anti...
