Title: Speech processing system
Inventor: HOLMES JOHN NICHOLAS
IPC: G10L25/15
Filed: 1997-10-13
Abstract: PURPOSE: A speech processing system employing formant data provides the advantage that formant frequencies are derived for comparison spectral cross-sections prior to processing, and can therefore be obtained by processes which are not practicable in real time; measurement of formant frequencies is then reduced to a matching process. CONSTITUTION: A speech processing system(10) incorporates a microphone(12) connected to a frequency selective pre-emphasis amplifier(14). Output from the amplifier passes to an analogue-to-digital converter(16) and to an excitation point finder(18). The excitation point finder provides input to a fast Fourier transformer(20) which in turn is connected to a formant analyzer(22). The formant analyzer provides input to a Hidden Markov Model (HMM) word matcher(24) and a computer(25). The Hidden Markov Model word matcher receives a second input from a word model store(26) and provides an output signal at an output(28). The computer is connected to a visual display unit(29).

Abstract: PCT No. PCT/NL98/00068 Sec. 371 Date Jul. 29, 1999 Sec. 102(e) Date Jul. 29, 1999 PCT Filed Feb. 4, 1998 PCT Pub. No. WO98/34025 PCT Pub. Date Aug. 6, 1998The present invention relates to a heating installation with a Stirling engine and Stirling-type heat pump integrated within a single pressure vessel. Two hot chambers and two cold chambers, as well as a working chamber in which a piston is mounted such that it oscillates freely, are located inside the pressure vessel. The chambers are in fluid communication with one another. A displacer is able to oscillate freely to and for between each pair of hot and cold chambers. By means of this Stirling engine of the fire piston type and the Stirling heat pump integrated therewith, a low-noise, low-maintenance and highly energy-efficient heating installation is formed which has a high net efficiency (COP value between 1.5 and 2.5). The heat from the cold chamber of the Stirling engine and from the hot chamber of the Stirling heat pump part is passed to a hot water system via a first and second heat exchanger. The heat from the exhaust gases is passed to a third heat exchanger. The heat exchangers may be connected in series or partly or wholly in parallel. Preferably the burner of the installation according to the present invention has a flat heat transfer behaviour to the Stirling engine's hot end upon increasing the power input of the burner, so that it can function as an auxiliary heater upon peak load demand.
