`2
`ing an On-Screen User Interface for a Subscription Televi
`Sion Terminal', incorporated herein by reference, can
`greatly enhance the ability of a user to acceSS available
`features. The System described in that application signifi
`cantly reduces the number of key presses and data entries
`required to utilize available features, moreover, a key pad is
`designed in Such a way as to group keys together in a manner
`to facilitate their use. However, even with Such an improved
`interface, certain tasks are simply not well-Suited for execu
`tion using a keypad on a Subscriber terminal unit or an
`asSociated remote control. For example, while a Subscriber
`might be very interested in using an EPG to determine the
`channel number and time for the next showing of a particular
`television show or to find all movies being shown in the next
`week Starring a particular actress, Such tasks are not easily
`implemented using menu Screens and key presses.
`
`SUMMARY OF THE INVENTION
`The present invention adds a Speech recognition interface
`to a Subscriber terminal unit in an information System for
`implementing Spoken control of electronic devices at the
`Subscriber location and of access to information transmitted
`to the Subscriber terminal unit. The Speech recognition
`interface enhances the interface of the Subscriber with the
`information System by allowing control using language
`which is naturally spoken by the subscriber. Such natural
`language control affords ease of use as well as permitting the
`implementation of tasks which are not easily implemented
`using menu Screens and key presses.
`In accordance with one aspect of the instant invention, a
`System for controlling a device includes a first receiver for

`
`BACKGROUND OF THE INVENTION
`1. Technical Field
`The present invention generally relates to an information
`System having a speech interface and, more particularly, to
`a Subscription information System including a Subscriber
`terminal unit which provides for control of electronic
`devices and access to information Services by Spoken com
`mands.
`2. Description of the Related Art
`The volume of information and number of features being
`made available to Subscribers in information Systems. Such as
`Subscription television Systems are continuously increasing.
`For example, the advent of optical fiber networks and links
`to telecommunication networks enables an almost limitleSS
`Supply of information and features to be provided to Sub
`Scribers. Already Subscription television Systems are being
`used for addressed message transmissions, pay-per-view
`programming, impulse pay-per-View programming, favorite
`channel features, and parental control. Cable television
`System operators may also provide text Services Such as
`news articles, Sports Scores, Stock market quotations, and
`weather reports. Relatively new features Such as Video game
`delivery, wide area network access, home Shopping, travel
`reservations Service, home banking, energy management,
`Video conferencing and other Such Services are also being
`provided.
`Recently, Some companies have begun offering electronic
`television Schedules for purchase by Subscription television
`providers who, in turn, provide the Schedules to their Sub
`Scribers. The Schedules contain a listing of television pro
`grams by time and channel, and are typically displayed as a
`35
`grid on the television screen. Such a system is shown in PCT
`Publication No. WO 92/04801, applied for by Insight
`Telecast, Inc. (hereinafter “the Insight System’) and incor
`porated herein by reference. That publication describes a
`display System for maneuvering a cursor through a televi
`Sion Schedule. The System also describes that a Subscriber
`can choose a program for recording by moving a cursor to
`the Selected program; the System will automatically program
`the Subscriber's video cassette recorder.
`Also recently, So-called near-video-on-demand Services
`have been introduced. These Services provide a simulation
`of the Videotape rental experience. One Such System is
`described in Walter, U.S. Pat. No. 5,168,353, incorporated
`herein by reference. Walker describes in column 4, lines
`18-27 that a converter may be enabled to descramble two
`channels carrying the same program at Staggered intervals.
`This allows returning to the same portion of the video after
`a pause equal to the Staggered time interval. The Walker
`patent gives as an example a Subscriber ordering a program
`that begins at 8:00 p.m. The converter unscrambles the 8:00
`showing as well as the 8:15 showing So that the viewer may
`return to the same point in the program after a fifteen minute
`break.
`This increase in information and features has generally
`resulted in a corresponding increase in the complexity of the
`subscriber's interface with the system. Since the subscrib
`er’s “comfort level” with an interface for accessing infor
`mation and features will often determine whether the Sub
`Scriber will utilize the information and features, there is a
`need for user-friendly interfaces. An interface Such as that
`described in commonly assigned copending application Ser.

`DETAILED DESCRIPTION
`The following conventions will be used throughout this
`detailed description. The <>symbols will be used to denote
`keypad commands input via the keypads to be described
`below, e.g., <Enter>. Quotation marks and capital letters will
`be used to designate spoken commands, e.g., “RECORD’ or
`“POWER ON.” Capital letters and italics will be utilized to
`indicate variables Such as channel numbers, etc.
`FIG. 1 is a generalized block diagram of an information
`system 10 in accordance with the instant invention. Infor
`mation system 10 includes an information distribution center
`12 which receives information from one or more remotely
`located information providers 14-1, . . . , 14-n and Supplies
`or broadcasts this information to a terminal unit 16. “Infor
`mation” as used herein includes, but is not limited to, analog
`Video, analog audio, digital video, digital audio, text Services
`Such as news articles, Sports Scores, Stock market quotations,
`and weather reports, electronic messages, electronic pro
`gram guides, database information, Software including game
`programs, and wide area network data. Alternatively or in
`addition, information distribution center 12 may locally
`generate information and Supply this locally generated infor
`mation to terminal unit 16.
`The information transmitted by information distribution
`center 12 to terminal unit 16 includes vocabulary data
`representative of a vocabulary of Spoken Sounds or words
`(“utterances”). This vocabulary provides, for example, for
`spoken control of a device 18 and for spoken control of
`access to the information transmitted by information distri
`bution center 12. Specifically, terminal unit 16 receives
`vocabulary data from information distribution center 12 and
`speech ("utterance”) data from a user. Terminal unit 16
`includes a processor for executing a speech recognition
`algorithm for comparing the Vocabulary data and the Spoken
`command data to recognize, for example, commands for
`controlling device 18 or commands for accessing informa
`tion transmitted by information distribution center 12. Ter
`
`6
`minal unit 16 then appropriately generates a command for
`controlling device 18 or for accessing information transmit
`ted by information distribution center 12. AS used herein, a
`Speech recognition algorithm refers to an algorithm which
`converts spoken audio input into text or corresponding
`commands. A speaker Verification algorithm refers to an
`algorithm which Verifies the claimed identity of a speaker
`based upon a Sample of the claimant's Speech. A speaker
`identification algorithm refers to an algorithm which iden
`tifies a speaker from a list of previously Sampled alternatives
`based upon audio input from a speaker. A Speaker identifi
`cation algorithm may be used, for example, to limit the
`ability to control the device and/or access information to
`particular Speakers.
`The vocabulary data transmitted from information distri
`bution center 12 to terminal unit 16 may, for example, be
`phoneme data. A phoneme is a member of the Set of the
`Smallest units of Speech that Serve to distinguish one utter
`ance from another in a language or dialect. Each Sound or
`spoken word in the Vocabulary may thus be represented by
`a combination of phonemes. Alternatively, the Vocabulary
`data may be template data generated by having a perSon or
`perSons Speak each Sound or word. Each spoken Sound or
`word in the Vocabulary may thus be represented by a
`respective corresponding template. It should be noted that
`although the system of FIG. 1 illustrates a system in which
`information from information providers 14-1,..., 14-n and
`the Vocabulary data are transmitted over the same commu
`nication link, the invention is not limited in this respect.
`Thus, information from information service providers 14-1,
`. . . , 14-n and the Vocabulary data may be transmitted over
`different communications links.
`Many different arrangements may be utilized to provide
`the speech data to terminal unit 16. In a first illustrative, but
`non-limiting, arrangement, a remote control is provided
`which includes a wireleSS microphone or related transducer
`for transmitting Sounds or words Spoken by a user to
`terminal unit 16 via electrical, optical, or radio frequency
`Signals. Terminal unit 16 then includes a receiver, an analog
`front end for conditioning the received signal, a codec for
`perform
