Spoken dialogue system, a spoken dialogue method and a method of adapting a spoken dialogue system

A dialogue system including: an input receiving data relating to a speech or text signal originating from a user; and a processor configured to: update a system state based on the input data using a state tracker model, the system state including probability values associated with each of plural possible values for each of plural categories; identify one or more relevant categories based on at least part of the updated system state information using an identifier model; define a set of information from stored information including plural action functions and categories, excluding categories not identified as relevant; generate a reduced system state, including the probability values associated with one or more of the plural possible values for each relevant category; determine an action based on the reduced system state and the set of information using a policy model; output information specified by the determined action at an output.

Dialogue system, a dialogue method and a method of adapting a dialogue system

A speech intelligibility enhancing system for enhancing speech to be outputted in a noisy environment, the system comprising: a speech input for receiving speech to be enhanced; a noise input for receiving real-time information concerning the noisy environment; an enhanced speech output to output said enhanced speech; and a processor configured to convert speech received from said speech input to enhanced speech to be output by said enhanced speech output, the processor being configured to: apply a spectral shaping filter to the speech received via said speech input; apply dynamic range compression to the output of said spectral shaping filter; and measure the signal to noise ratio at the noise input, wherein the spectral shaping filter comprises a control parameter and the dynamic range compression comprises a control parameter and wherein at least one of the control parameters for the dynamic range compression or the spectral shaping is updated in real time according to the measured signal to noise ratio.

Speech processing system for enhancing speech to be outputted in a noisy environment

A speech intelligibility enhancing system for enhancing speech, the system comprising:

Speech processing system and speech processing method

A method of animating a computer generation of a head and displaying the text of an electronic book, such that the head has a mouth which moves in accordance with the speech of the text of the electronic book to be output by the head and a word or group of words from the text is displayed while simultaneously being mimed by the mouth, wherein input text is divided into a sequence of acoustic units, which are converted to a sequence of image vectors and into a sequence of text display indicators. The sequence of image vectors is outputted as video such that the mouth of said head moves to mime the speech associated with the input text with a selected expression, and the sequence of text display indicators is output as video which is synchronized with the lip movement of the head.
