A system for enhancing the signal-to-noise ratio of a speech signal is avoided. A plurality of local energy maximums associated with a speech signal are determined. Presumably, each of these local energy maximums defines a speech pitch period. Typically, human pitch periods are approximately 100-400 Hz depending on the sex and age of the speaker. Because human speech typically includes more energy near the beginning of a pitch period than at the end of the pitch period, and background noise tends to remain relatively constant throughout the pitch period, the speech signal may be enhanced by increasing the energy associated with the beginning of the pitch period and/or by decreasing the energy associated with the end of the pitch period. Preferably, the amount of energy increase in the earlier portion of the pitch period is approximately equal to the amount of energy reduction in the later portion of the pitch period. In this manner, the total energy remains the constant.

A voice sample characterization front-end suitable for use in a distributed speech recognition context. A digitized voice sample is split between a low frequency path and a high frequency path. Both paths are used to determine spectral content suitable for use when determining speech recognition parameters (such as cepstral coefficients) that characterize the speech sample for recognition purposes. The low frequency path has a thorough noise reduction capability. In one embodiment, the results of this noise reduction are used by the high frequency path to aid in de-noising without requiring the same level of resource capacity as used by the low frequency path.

An audio filter consists of two substantially identical stages with different purposes. The first stage () whitens detected noise, while preserving speech or other audible information in an undistorted manner. The second stage () effectively eliminates the residual white noise. Each stage, in one embodiment, includes a Mel domain based error minimization stage (). A two stage Mel-frequency domain Wiener filter () is designed for each speech time frame in the Mel-frequency domain, instead of linear frequency domain. Each Mel domain based error minimization stage () minimizes the perceptual distortion and reduces the computation requirement to provide suitably filtered audible information.

A method () or system () of facilitating goal based calendar management can include creating a calendar item () from a user entry () and an external entry (), determining () if the calendar item is a policy related item, extracting policy attributes () for the calendar item, determining () if an action is required based on the policy attributes, the user entry, and the external entry, and executing the action based on the policy attributes. The method can further include presenting () a suggested action based on the policy attributes and accepting an entry () corresponding to the suggested action. The method can further present a modification of the external entry based on the policy attributes and accept an entry corresponding to the modification of the external entry. The method can also present an action related to a common context as a result of an analysis of the attributes.

A system includes a first communications device [] to participate in a conversation with at least a second communication device []. An intelligent communication agent [] monitors the conversation for at least one keyword. In response to detecting the at least one keyword, the intelligent communication agent performs a search for multimedia content corresponding to the at least one keyword and retrieves the multimedia content. A logic engine [] determines relevant content of the multimedia content based on at least one of a conversation profile and at least one user profile for at least one of a user of the first communication device and at least a second user of the at least a second communication device. A transmission element [] transmits the relevant content to at least one of the first communication device, the at least a second communication device, and a predetermined multimedia device [

Noval abnormally glycosylated a. sub. 2 -macroglobulins have been found in sera of patients suffering from autoimmune diseases. Such abnormally glycosylated materials have been isolated. The presence of these abnormally glycosylated materials in a patient's serum provides a means for diagnosing such diseases.
