International Classification:

H04L 9/00

US Classification:

713186

Abstract:

A method () and system () for using a biometrically enabled password can include an input device () capable of entering a password entry and a processor () coupled to the input device. The processor can monitor ( or ) a cadence such as monitoring a keystroke signature, store the cadence of the password entry, compare () the cadence of a subsequent password entry with the cadence of at least one previous password entry, establish () a stability metric with respect to the cadences compared, and require () both the password entry and the cadence once the cadence meets the stability metric. The processor can require only the password entry until the stability metric for the cadence is achieved. The processor can also determine () if the password entry is new and optionally require () only the password entry to enter the system if determined as new.

International Classification:

G10L 15/26

US Classification:

704235, 704257, 704 9

Abstract:

The present invention can include a method for tuning grammar option weights of a phrase-based, automatic speech recognition (ASR) grammar, where the grammar option weights affect which entries within the grammar are matched to spoken utterances. The tuning can occur in an unsupervised fashion, meaning no special training session or manual transcription of data from an ASR session is needed. The method can include the step of selecting a phrase-based grammar to use in a communication session with a user wherein different phrase-based grammars can be selected for different users. Feedback of ASR phrase processing operations can be recorded during the communication session. Each ASR phrase processing operation can match a spoken utterance against at least one entry within the selected phrase-based grammar. At least one of the grammar option weights can be automatically adjusted based upon the feedback to improve accuracy of the phrase-based grammar.

US Classification:

604060000

Abstract:

An apparatus for selectively dosing a solid is provided and includes (1) a flexible guide tube that include a first end and an opposing second end and has a bore formed therethrough from the first end to the second end; (2) a dispensing tip disposed at the first end of the guide tube and including a bore formed completely therethrough and defining a reservoir fore holding one or more dosing solids until actuation of the apparatus; and (3) a stylet that is dimensioned so as to be slideably received within through the bore of the flexible guide tube, the stylet having a first end and an opposing second end. With the first end of the stylet being for contact with one or more dosing solids to cause discharge thereof through the dispensing tip.

International Classification:

US Classification:

704247

Abstract:

A computer-implemented method, system and/or program product update voice prints over time. A receiving computer receives an initial voice print. A determining period of time is calculated for that initial voice print. This determining period of time is a length of time during which an expected degree of change in subsequent voice prints, in comparison to the initial voice print and according to a speaker's subsequent age, is predicted to occur. A new voice print is received after the determining period of time has passed, and the new voice print is compared with the initial voice print. In response to a change to the new voice print falling within the expected degree of change in comparison to the initial voice print, a voice print store is updated with the new voice print.
