IPC: G10L19/26
Filed: 1996-05-02
Abstract: A  speech  modification  or  enhancement  filter,  and apparatus, system and method using the same.   Synthesized speech signals are filtered to generate  modified synthesized speech signals.   From spectral information represented as a multi-dimensional vector, a filter coefficient is determined so as to ensure that formant characteristics of the modified synthesized speech signals are enhanced in comparison with those of the synthesized speech signal and in accordance with the spectral information.    The spectral information can be any one of LSP information, PARCOR information and LAR information.  A degree of freedom of design of the speech modification filter used for the aural suppression of quantizing noise contained in the synthesized speech signals is thus heightened leading to the improvement of intelligibility of said synthesized speech signals.   A good formant enhancement effect can be obtained without allowing any perceptible level of distortions to occur within a range of permissible spectral gradients.

Patent CA-2206132-A1 (CA)
Inventor: AHMADI BABAK
IPC: G06F17/30
Filed: 1995-12-11
Abstract: A computer-implemented method for information organization, wherein atomic information can be both static and dynamic, but the compound information (e.g., associations, groupings, sets, etc.) of such atoms always remain dynamic.    Unless otherwise directed, a compound information entity is always dynamically determined and generated. This determination is based on the processing of a defined condition, wherein all atoms qualifying the condition are included in the compound. This dynamic determination eliminates the need to "update" the compound, when atoms and/or compounds common to two or more compounds are changed.   Further, each information compound can be dynamically generated based on an existing definition for that compound.
