Abstract:
A portable device, such as a cellular telephone, engages the user in a challenge-response sequence that is based on recognition of the user's utterance and also upon verification of the user's speech patterns or voiceprint. The challenge-response protocol presents the user with an unexpected challenge word, which the user is then requested to respond to. The system maintains a secure data store of challenge words which it adapts and augments as the user makes use of the portable device. The portable device provides the user with a convenient, single access point through which he or she can authenticate with a variety of disparate secure devices ranging from door locks, ATM machines, financial institutions and third-party business associates.
Abstract:
A speech recognition and control system including a receiver for receiving an audio input, an event detector for analyzing the audio input and identifying at least one event of the audio input, a recognizer for interpreting at least a portion of the audio input, a database including a plurality of rules, and a controller for generating a control command based on the at least one event and at least one rule.
Abstract:
The system includes a remotely controlled medical system having a controller in communication with a command device incorporating a microphone. The system further includes a medical device operable by the controller and a sound generator coupled to the controller. The command device incorporating a microphone is paired to the controller for operating the medical device by detecting the sound. The command device incorporating a microphone transmits a signal in response to the sound to the controller to verify the pairing of the command device incorporating a microphone to the controller such that the controller will only operate the medical device in response to a command issued near the sound generator.
Abstract:
A system for operating one or more devices using speech input including a receiver for receiving a speech input, a controller in communication with the receiver, software executing on the controller for converting the speech input into computer-readable data, software executing on the controller for generating a table of active commands, the table including a portion of all valid commands of the system, software executing on the controller for identifying at least one active command represented by the data, and software executing on the controller for transmitting the active command to at least one device operable by the active command.
Abstract:
A call routing and supervising system includes an input receiving customer speech from a remote location, and a voice characteristics extractor extracting voice characteristics from the customer speech, such as language/dialect/accent, age group, gender, and eigendimension coordinates. A customer service representative selector selects one or more customer service representatives based on profiles of the customer service representatives respective of customers having voice characteristics similar to the extracted voice characteristics. In other aspects, a call monitor automatically analyzes dialogue between the customer and the customer service representative, such as detected interruptions, tracked dialogue turns, and recognized key phrases indicating frustration, polity, and/or resolution characteristics of dialogue. The call monitor records performance of the customer service representative respective of customers having the voice characteristics. Automatic call rerouting and/or real-time instruction of call center personnel can also be accomplished based on analysis results.
Abstract:
An automated hotel attendant is provided for coordinating room-to-room calling over a telephone switching system that supports multiple telephone extensions. A hotel registration system receives and stores the spelled names of hotel guests as well as assigns each guest an associated telephone extension. A lexicon training system is connected to the hotel registration system for generating pronunciations for each spelled name by converting the characters that spell those names into word-phoneme data. This word-phoneme data is in turn stored in a lexicon that is used by a speech recognition system. In particular, a phoneticizer in conjunction with a Hidden Markov Model (HMM) based model trainer serves as the basis for the lexicon training system, such that one or several HMM models associated with each guest name are stored in the lexicon. An automated attendant is coupled to the speech recognition system for converting a spoken name of a hotel guest entered from one of the telephone extensions into a predefined hotel guest name that can be used to retrieve an assigned telephone extension from the hotel registration system. Next, the automated attendant causes the telephone switching system to call the requested telephone extension in response to the entry of the spoken name from one of the telephone extensions.
Abstract:
The mixed decision tree includes a network of yes-no questions about adjacent letters in a spelled word sequence and also about adjacent phonemes in the phoneme sequence corresponding to the spelled word sequence. Leaf nodes of the mixed decision tree provide information about which phonetic transcriptions are most probable. Using the mixed trees, scores are developed for each of a plurality of possible pronunciations, and these scores can be used to select the best pronunciation as well as to rank pronunciations in order of probability. The pronunciations generated by the system can be used in speech synthesis and speech recognition applications as well as lexicography applications.
Abstract:
A voice controlled surgical system including a wireless command microphone receiving audio input, a voice control module for generating commands from the audio input received by said wireless command microphone, a detection module for generating signals indicative of a proximity of said wireless command microphone, a switch module for disabling the commands in response to one or more of the signals, and an alarm module activated in response to the one or more of the signals.
Abstract:
A system and method for managing workflow of a medical procedure, including a control and at least one detector such as a sensor, where the control interprets a user input to control the workflow of the medical procedure. The system and method include multiple input modalities and hazard mitigation measures to control the medical procedure and/or control various medical devices in an operating room.
