Abstract: A caller is prompted to enunciate (105) an alphanumeric phrase comprising a number of characters. Having reset (104) to zero a cumulative recognition distance register or its equivalent, each character is captured and analyzed (106) and a form of acoustic dissimilarity calculated (108) in relation to a previously stored and corresponding reference character of a reference alphanumeric string. The register is incremented by a quantified difference between the reference character and the captured character and then an assessment (112) is made to determine which of the reference alphanumeric strings has the lowest cumulative recognition distance implying that this was the alphanumeric phrase spoken by the caller. Robust phrase recognition is thus achieved by the exemplified methodology of Figure 6.

Abstract: A system and method for enabling a caller to obtain access to services via a telephone network by entering a spoken first character string having a plurality of digits. Preferably, the method includes the steps of prompting the caller to speak the first character string beginning with a first digit and ending with a last digit thereof, recognizing each spoken digit of the first character string using a speakerindependent voice recognition algorithm (49a, 69a), then following entry of the last digit of the first string, initially verifying the caller's identity using a voice verification algorithm (49b, 66b). After initial verification, the caller is again prompted to enter a second character string, which must also be recognized (49c, 66c) before access is effected.

Abstract: A method for recognizing a spoken word in the presence of interfering speech, such as a system-generated voice prompt, begins by echo cancelling the voice prompt and any detected speech signal to produce a residual signal. Portions of the residual signal that have been most recently echo-cancelled are then continuously stored in a buffer. The energy in the residual signal is also continuously processed to determine onset of the spoken word. Upon detection of word onset, the portion of the residual signal then currently in the buffer is retained, the voice prompt is terminated, and the recognizer begins realtime recognition of subsequent portions of the residual signal. Upon detection of word completion, the method retrieves the portion of the residual signal that was retained in the buffer upon detection of word onset and performs recognition of that portion. The recognized portions of the word are then reconstructed to determine the spoken word.

Abstract: An advanced electronic vehicle alarm system allows control of alarm functions to be accomplished using specific spoken commands. A microphone converts speech into time-variant voltage levels which are amplified and sent to a analog-to-digital converter and digitized. The digitized data is then processed by a speech recognition subsystem. The speech recognition subsystem separates extraneous speech from words and provides corresponding output signals when control words are recognized. The output signals are preferably employed by the alarm system to operate door locking and unlocking controls, to operate a loud audible siren and/or horn, to operate vehicle light controls, to provide engine cut-off control, to provide engine starting control or to operate a response indicator incorporated in the main alarm processing unit. The response indicator provides verbal responses to confirm spoken commands. A speaker verification capability is also included in the speech recognition subsystem to allow for secured operation of the vehicle alarm system.

Abstract: Voice activated dialing is described for use in a mobile telecommunications system. A voice input is received from a wireless network user. A telephone number to be dialed is determined by using speaker independent speech recognition to interpret a string of spoken digits in the voice input to determine the telephone number, or using speaker dependent speech recognition to interpret a spoken word in the voice input to determine the telephone number. A telephone call is then initiated by dialing the telephone number.
