Definitions

  • This invention relates generally to voice recognition, and more particularly to speaker dependent voice recognition applied to information communication systems, and is more specifically directed toward a method for programming communication devices 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.
  • voice recognition technology has not found wide use due to the complexity of its implementation, and requirements for a large amount of electronic storage (memory).
  • 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.
  • the voice recognition information commonly referred to as a "codebook”
  • mass codebook storage in each subscriber unit may prove impractical due to space or cost considerations.
  • An alternative may be to use speaker independent technology, however, speaker independent devices are typically more complex and costly.
  • voice recognition technology When applied to information communication devices, voice recognition technology raises several concerns.
  • One major concern comprises the recognition that communication devices are typically used by more than one individual.
  • police vehicles are generally in service for three eight-hour shifts, during which at least three officers use the vehicle.
  • the officers using the vehicle may be anyone on the entire police force. Therefore, each radio must contain a codebook for each officer on the force. This would significantly increase the cost of the radios. Additionally, codebook maintenance costs would be significant since the radios must be updated with each change in personnel.
  • Another concern is the increase in radio size.
  • Contemporary state-of-the-art communication devices are designed so as to minimize their physical size. The addition of several memory devices, or a memory printed circuit board, may increase the size of the device beyond that desired by the consuming public. This is a particular concern in the personal pager and handheld radio products.
  • One solution may be to store the codebooks of only a few individuals thereby reducing the amount of required memory.
  • Another approach may be to have each radio contain only enough memory for a single codebook, which must be retrained for each person.
  • Speaker dependent voice recognition devices must be "trained” to respond to each individual. Training is accomplished by having an individual repeat control words several times until the device has been "trained” to recognize that word as spoken by that individual.
  • training is a time consuming process and may be very inefficient in certain markets, such as police and fire protection, where rapid activity is ordinarily required. Accordingly, a need exists in the art to permit information communication devices to be programmed to respond to the voice commands of several individuals in an efficient and organized manner.
  • a communication device may be programmed to recognize voice commands via a portable programming apparatus.
  • An identification code is employed to access particular voice recognition information (codebook) from a repository containing one or more voice recognition codebooks within the portable programming device.
  • the programming device responds by transmitting the identified codebook to at least one communication device, which stores the codebook therein. Thereafter, the communication device may respond to the voice commands of that individual. In this way, the communication device may be rapidly reprogrammed to accommodate changing operators.
  • Figure 1 is an illustration of a programming device in accordance with the present invention, and a vehicle having a mobile subscriber unit installed there;
  • Figure 2 is an illustration of an alternate programming device in accordance with the present invention, and a mobile subscriber unit;
  • FIG 3 is a block diagram of the programming device of Figure 1 or Figure 2;
  • FIG. 4 is a block diagram of a subscriber unit according to the present invention.
  • a radio frequency programming device (10) communicating with a vehicle (12) having a mobile subscriber unit installed therein.
  • the programming device (10) operates as a repository of all of the codebooks for individuals that may operate the subscriber unit.
  • the total collection (or library) of codebooks may be apportioned between two or more programming devices.
  • the subscriber units may be mobile units, portable units, or control stations.
  • a portable subscriber unit is designed to be carried on or about the person
  • a mobile subscriber unit is designed to be mounted into vehicles
  • control stations are permanent or semi-permanent installations installed in buildings or other fixed locations.
  • subscribers collectively refers to portable units, mobile units or control stations.
  • the programming device thus becomes a central repository (library) of the several codebooks.
  • a separate facility may be used to provide "training" of the subscriber units. For example, all codebooks for an entire police force may be created by training a subscriber unit (or its simulated equivalent) at the police station, after which the newly created codebooks may be transferred to the programming device via any convenient means. In this way, the codebook library may be maintained.
  • the programming device may allow for creation of codebooks by having subscriber operators train the programming device itself.
  • Each of the subscriber units contain enough codebook memory to store the codebook for at least one individual.
  • codebook transfer is accomplished by entering a codebook identification code on a keypad (14) and depressing a transfer activation button (or switch) (16) .
  • the present invention also contemplates several alternatives to effect codebook transfer.
  • One alternate comprises providing each operator with an identification card (or module) that may be inserted into the programming device, which causes an automatic transfer of the appropriate codebook from the programming device (10) to the subscriber unit.
  • the programming device may itself be voice controlled (speaker dependent) to transfer an identified codebook. In this way, codebook transfer could be controlled since the programming device would only respond to a limited number of speakers.
  • the programming device may employ a limited version of . speaker independent voice recognition technology, which nay be used to effect codebook transfer.
  • the operator of the mobile subscriber unit also carries an associated portable subscriber unit, which may be used to maintain communication when the operator is out of the vehicle.
  • the programming device (10) may simultaneously transfer a codebook to a mobile subscriber unit and its associated portable unit.
  • the operator may partially (or entirely) control the operation of the subscriber unit by voice commands.
  • voice commands may be used in conjunction with manually entered commands (or vice versa)- to execut a desired function.
  • the codebook for the new operator may be rapidly transferred as described above.
  • the memory in the subscriber may be expanded (within siz and cost constraints) to retain a limited number of the last used codebooks in a first-in-last-out manner.
  • the codebook of the current user and the prior two operators may be retained in the subscriber unit. I 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.

Abstract

On peut programmer un dispositif de communication (22) pour qu'il reconnaisse des instructions vocales (30, 48, 60) à l'aide d'un appareil de programmation portatif (54' ou 68). On emploie un code d'identification pour accéder à des informations (code) de reconnaissance de voix particulières provenant d'un dépôt de codes de reconnaissance de voix contenu à l'intérieur dudit dispositif de programmation portatif. Ledit dispositif de programmation répond en transmettant le code identifié à au moins un dispositif de communication stockant le code (40). Ensuite, le dispositif de communication peut répondre aux instructions vocales de l'individu.
