Abstract: A description of stimuli used for functional verification of a circuit design is received. The description includes classes of variables and the variable include random variables. A coverage model for the functional verification of the circuit design is also received. The coverage model includes coverage targets that are functions of the variables. A processing device generates stimuli for multiple iterations of the functional verification, as follows. Context values, which include values of the random variables for the stimuli, are maintained. The values of the random variables in an individual class are randomized, and the randomization of the random variables in the individual class is biased to hit the coverage targets given the context values for the random variables outside the individual class. Whether the coverage targets are hit by the generated stimuli is determined.

Abstract: A system and method may provide processing of a communication request for establishing a communication session to communicate signals between an interactive voice response device and a first communication device over a network, identifying a monitoring request requesting monitoring of the communication session, and instructing establishment of a monitoring session for conferencing a second communication device into the communication session to receive the signals communicated between the interactive voice response device and the first communication device at the second communication device.

Abstract: An interactive speech recognition process and system is disclosed. A user is prompted for selection of one of a number designated phrases represented in a grammar database. Speech recognition processing is applied to an uttered response from the user to match data in the grammar database, thereby identifying the selected phrase. The user is requested to confirm a determined match. If the match is not confirmed, the data corresponding to the matched phrase is removed from the grammar database and the user is re-prompted to select from the remaining phrases.
