  • Patent number: 5815551
    Abstract: A system D interfaces with a multiplicity of individual terminals T1-Tn of a telephone network facility C, at the terminals callers are prompted by voice-generated instructions to provide digital data that is identified for positive association with a caller and is stored for processing. The caller's identification data is confirmed using various techniques and callers may be ranked and accounted for on the basis of entitlement, sequence or demographics. Callers are assigned random designations that are stored along with statistical and identification data. A break-off control circuit may terminate the computer interface aborting to a terminal for direct communication with an operator. Real-time operation processing is an alternative to stored data. The accumulation of stored data (statistical, calling order sequence, etc.) is variously processed and correlated as with developed or established data to isolate a select group or subset of callers who can be readily identified and reliably confirmed.

  • Patent number: 5799065
    Abstract: The call routing device plugs into existing extensions of the office telephone network or PBX system and acts as a "virtual" operator, prompting incoming callers to spell the name of the desired recipient. The speech recognizer uses a multipass procedure employing Hidden Markov Models and dynamic programming. The N-best hypotheses are propagated between passes, allowing the more computationally costly routines to be reserved until the final pass, when the size of the search space is significantly reduced. The routing device prompts the user to confirm that the selected name is correct, whereupon the device signals the telephone network to automatically switch the incoming call to the telephone extension of the selected recipient.

  • Patent number: 5740242
    Abstract: An echo canceler is disclosed having a voice detector. When the voice detector detects the absence of input signals, the echo canceler is trained. In the training mode, the echo canceler receives an impulse signal from an impulse generator, as input through a switching device. When the input of the echo canceler is the impulse signal, a switch is turned off, a signal on a receiving line is stored in a tap coefficient memory, and the impulse signal on a transmitting line is stored in a transmission signal memory. Using the signals stored in the two memories, a convolution operation is performed by a convolution arithmetic unit. The data of the tap coefficient memory directly before the end of training are used for the tap coefficients after the training period.

  • Patent number: 5737408
    Abstract: An echo cancelling system has two echo cancellers for cancelling a channel echo and a room echo, respectively. In order to obviate echo estimation errors, the echo canceller at the channel side performs estimation only when an input signal from a channel is absent and a microphone input signal is present. The echo canceller at the room or acoustic side executes estimation only when a microphone input signal is absent and an input signal from the channel is present. A necessary amount of suppression is applied to either the receipt side or the transmission side until the echo canceller estimates an echo, so that a howling margin is guaranteed.
