Definitions

  • This invention relates generally to voice recognition, and more particularly to speaker dependent voice recognition applied to paging communication systems, and is more specifically directed toward a method for programming pagers to recognize and respond to voice commands.
  • Voice recognition technology has been recognized as an advantageous feature for many product applications. Such technology may be employed to render a product partially or entirely controllable by voice commands in situations where hands-on control is impossible or impracticable.
  • Speaker dependent voice recognition devices are designed to respond to a particular individual. Stored within such devices are speaker specific parameters, such as, for example, variations in the vocal tract response, pitch period, short-term speech power, and amplitude of the short-term speech spectra.
  • voice recognition When applied to paging communication systems, voice recognition raises several concerns.
  • One such concern involves the problem of storing the voice recognition information (commonly referred to as a
  • a single pager may be desirable to enable a single pager to respond to the voice commands o more than one individual (subscriber) .
  • a typical situation may be in a company setting wherein a pager is temporarily provided to an individual that must be available to respond to some emergency or important situation.
  • a single pager may be shared between, for example, maintenance personnel operating in working shifts (i.e., three eight-hour shifts) . Therefore, to provide voice control, the codebook for each individual must be stored within the pager.
  • mass codebook storage may significantly increase the cost of the pagers. Additionally, codebook maintenance costs would be significant since the pagers must be updated with each change in personnel.
  • an individual desiring to operate a pager via voice commands sends a message to a repository of voice recognition codebooks requesting access to a particular codebook.
  • the repository device(s) respond by transmitting the codebook of that individual to at least one pager, which stores the codebook therein. Thereafter, the pager may respond to the voice commands of that individual. In this way, pagers may be rapidly reprogrammed.

  • the paging controller (18) includes appropriate address encoders and decoders, memory, processing equipment, real-time clocks and other associated functions well known in the paging arts. Additionally, the paging controller (18) may access a data base (20) of voice recognition information (codebooks) , which the controller may route to the transmitter (16) for transmission to at least one pager (14) .

  • one or more paging terminals (26) may be directly coupled to the controller (18) .
  • the operation of the system (10) shown in Figure 1 is such that the pagers (14) are capable of receiving messages in any of several message formats or signalling patterns.
  • message formats include, but are not limited to, the Golay Sequential Code (GSC) , and the British Post Office paging system format (POCSAG) . While just two message formats have been mentioned, the present invention contemplates the use of any suitable message format or signalling.

  • the central repository is preferably associated with a facility that may be used to provide "training" of the subscriber units. In this way, new paging subscribers may create a personal codebook by training a pager (or its simulated equivalent) at the central facility.
  • the centralized repository storage of the codebooks facilitates maintenance of the codebook library. Alternately, the repository may be distributed among several locations within a given geographic area. However, this approach may require tighter controls and coordination to adequately maintain the codebook libraries.
  • Each of the pagers (14) contain enough codebook memory to store the codebook for at least one individual. Thus, before an individual may use the pager, his or her codebook must be transferred (down-loaded) from the central repository (12) to the pager (14) .
  • an individual desiring to operate a pager (14) may transmit a message to the central repository (12) identifying and requesting a particular codebook from the codebook library.
  • the present invention contemplates several alternatives to generating the codebook request message. As a first method for generating a codebook request, an identification code may be entered on a keypad (or equivalent) of a paging terminal (26) and transmitted to the central repository (12) .

  • a codebook identification code may be transmitted, such as, for example, by using the DTMF telephone tones, which may respond by down-loading a particular codebook to a particular pager (14) .
  • the paging controller (18) may employ a limited version of speaker independent voice recognition technology, which may be used to generate the codebook down-load request.

  • the codebook for the new subscriber may be rapidly down-loaded as described above.
  • the memory in the subscriber may be expanded (within size and cost constraints) to retain a limited number of the last used codebooks in a first-in-last-out manner. For example, the codebook of the current user and the prior two subscribers may be retained in the subscriber unit. In this way, if the same three individuals operating the subscriber during the three operating shifts were ordinarily repeated day to day, no reprogramming of the subscriber unit would be required.
  • the present invention contemplates that the central repository (12) may contain a data base of the subscribers and the associated pagers that they customarily operate. At each shift change, the central repository (12) may automatically down-load the codebook for the next subscriber based upon time of day (or other suitable parameters) . If a change in personnel occurs, due to illness or unavailability, a supervisor may enter a new name into the roster (data base) , and that individual's codebook may be automatically down-loaded to the subscriber unit. This approach has the advantage of minimizing the over-the-air requests for new codebooks to those situations where a subscriber change occurs unexpectedly.

  • Other features are somewhat more subtle, such as, for example, “Volume Three” (the pager responding by increasing or deceasing the volume to level three) ; “Protect Message Five” (the pager responding by protecting a message from being lost even by an "Erase All Messages” command) .

Abstract

Une personne désirant se servir d'un dispositif de recherche de personne (14 ou 14') par des instructions vocales (32, 48, 50) envoie un message à un dépôt de codes de reconnaissance de voix demandant l'accès à un code particulier. Le ou les dispositifs de dépôt répondent en transmettant (54) le code de cette personne à au moins un dispositif de recherche de presonne stockant ledit code (30). Dans un second mode de réalisation, chaque personne faisant fonctionner un dispositif de recherche de personne (14 ou 14') par instructions vocales comporte un module de code (30, 42), contenant une mémoire adaptée dans laquelle au moins le code de l'utilisateur est stocké. L'introduction du module de code dans ledit dispositif de recherche de personne fait que ce dernier peut être au moins partiellement commandé par les instructions de cet utilisateur.
