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...

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)...

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...

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...

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...

The present invention comprises a system and method for speech verification using a confidence measure that includes a speech verifier which compares a differential score for a recognized word to a predetermined threshold value, where a recognized word is the word model that produced the highest recognition score. In one embodiment, a single threshold is used for each word in a vocabulary. In another embodiment, each word model has an associated threshold, so that a differential score for a reco...

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.

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...

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 distributed speech recognition system includes at least one client station and a server station connected via a network, such as Internet. The client station includes means for receiving the speech input signal from a user. A speech controller directs at least part of the speech input signal to a local speech recognizer. The, preferably limited, speech recognizer is capable of recognizing at least part of the speech input, for instance a spoken command for starting full recognition. In depende...
