`
`The present invention generally relates to audio recording
`devices, and in particular, to voicemail systems.
`
`BACKGROUND OF THE INVENTION
`
`ill
`
`15
`
`Voicemail systems allow telephone callers to leave
`recorded messages for called parties when the called parties
`are unavailable. Most voicemail systems record messages if
`the called party's phone line is either in use or does not
`answer. In either case, the voicemail system answers the
`phone call and records the message. Typically, the message
`is digitized and stored on a computer hard disk for later
`playback by the called party.
`To play recorded messages, a mailbox owner calls the °
`voicemail system and aocemes stored voice messages using
`a sequence of touchtone or voice commands. In response to
`these commands, the voicemail system can perform various
`functions with respect to message playback. For example, a
`mailbox owner can fast forward, rewind, delete or skip a
`message during playback. In some voicemail systems, dur-
`ing a message playback, the listener can fast forward or
`rewind either to the end of the message or a specific amount
`of time. Using these voicemail systems to play back specific
`middle portions of messages. it is frequently the case that
`listeners must repeatedly enter fast-forward commands to
`get the systems to skip ahead to the desired places in the
`messages.
`
`30
`
`Although the playback functions of currcntly—available
`voicemail systems are adequate in many situations, there is ‘
`room for improvement. For instance, some users may find it
`inconvenient and time consuming to select specific portions
`of messages for playback using conventional fast forward
`and rewind functions available with some voicemail sys-
`IEIHS.
`
`40
`
`Accordingly, there is a need for an improved voicemail
`system that permits users to conveniently select portions of
`stored messages for playback.

`
`DETAILED DESCRIPTION OF THE
`PRl:lSEN”l‘LY PREFERRED F.MBODlMEN'l‘(S)
`
`It is an advantage of the present invention to provide a
`voicemail system that permits users to bookmark messages
`during message playback. Bookmarks can be set by entering
`appropriate touch-tone or voice commands. A bookmark
`defines a starting point within the message at which subse-
`quent playbacks of the message can begin. The ability to

`bookmark messages significantly improves the convenience
`of playing back specific portions of stored voicemail mes-
`sages.
`
`Turning now to the drawings. and in particular to FIG. 1,
`there is illustrated a How chart 20 illustrating a method of
`setting a voicemail bookmark in accordance with an
`embodiment of the present invention. In step 22, a user calls
`into a voicemail system. After connect ing to the voicemail
`system, the user enters information conventionally associ-
`ated with accessing a voicemail box such as a user II) andfor
`password. Provided that there are voicemail messages stored
`for the user. the user requests message playback (step 24).
`During playback of the message,
`the user can enter a
`command to set
`a voicemail bookmark (step 26). The
`command can be entered using one or more touch—tone
`digits or voice commands at
`the user’s telephone. The
`voicemail system responds to this command by setting a
`bookmark pointer corresponding to the message being
`played back.
`According to one aspect of the invention, one of the digits
`entered can specify a timing offset that causes the playback
`starting point to be set at a specified period oftime before the
`point in the message at which the bookmark request is made.
`This permits a "warm-up” period to be added to the book-
`marked voicemail message.
`In step 28, the bookmark pointer is stored by the voice-
`mail system so that the user can subsequently access the
`message at the place indicated by the bookmark. The book-
`mark pointer can specify a computer memory location
`associated with a file containing the content of the stored
`voicemail message. In addition, the bookmark pointer can be
`based, in part, on the timing oflset entered by the user.
`In step 30, a voice message indicator generated by the
`voicemail system is updated to indicate that the bookmarked
`message is no longer a new message, and has been book-
`marked by the user. The voicemail system can be configured
`to cause the message indicator to be displayed at the user’s
`terminal unit using a standard protocol and display interface.
`FIG. 2 is a block diagram of a telecommunication system
`60 in accordance with another embodiment of the present
`invention. The telecommunication system 6|]
`includes a
`plurality of terminal units 64, a telecommunication switch
`66, and a voicemail system 68. The terminal units 64can be
`any suitable end-user device, such as a telephone, cellular
`phone, or the like, for permitting voice communication over
`a commercially-available telecommunications network 62.
`The switch 66 can be any suitable commercially-available
`telecommunication switch,
`located at
`a private branch
`exchange (PBX) or central office, for allowing the terminal
`units 64 to access the voicemail services of the voicemail
`system 68.
`The voicemail system 68 can be a voicemail server
`communicating with the switch 66 over a standard interface.
`The voicemail system 68 includes a processor 70, voicemail
`database {DB} 72, a memory 73, and interface port 76, a call
`answering devicefdual-tone of multi frequency (DTMF)
`interface 78, a voice playback subsystem 80, a voice
`recorder 82, and a speech recognition subsystem 84. A
`memory 73 can store a user interface program 74 that is
`executable by the processor 70. The user interface program
`74 includes a bookmarking procedure 86 that permits the
`voicemail system 68 to provide the voicemail bookmarking
`feature.
`
`The voicemail system 68 can be implemented using a
`Compact Service Node, available from Lttcent
`Technologies, Inc., configured and programmed to perform
`
`

`
`US 6,625,261 B2
`
`3
`the functions disclosed herein. The switch 66 can be an
`advanced intelligent network (AIN) compatible switch, such
`as the SESS switch, also available from I..ucent
`Technologies, Inc.
`FIG. 3 illustrates a data structure 100 of an exemplary
`voice mailbox stored in the voicemail DB 72. Each voice
`mailbox in the database 72 has associated with it a user ID
`102. Associated with each user ID 102,
`is one or more
`message IDs 104 for identifying voicemail messages stored
`in the DB 72 for the user. Also associated with each user ID
`102 is one or more bookmark IDs 106 for identifying
`voicemail bookmarks associated with the owner of the
`voicemail box.
`
`For each message ID 104, the DB 72 stores an associated
`voice message record 108. The voice message record 108
`can contain a sender ID 110 identifying the caller leaving the
`message, a time stamp 112 indicating the time at which the
`message was recorded and one or more system tlags 114 for
`configuring system parameters and functions relating to the
`message. The message record 108 also includes the message
`content llti, which can include the recorded voice message
`digitized into a format suitable for storage in the DB 72 and
`for playback by the voice playback subsystem 80. The
`message content 116 can be compressed andfor encrypted
`using standard speech processing algorithms.
`The bookmark [D 106 has associated with it a bookmark
`record 118 containing a message ID 120 and a bookmark
`pointer 122. The message ID 120 identities the bookmarked
`message. The bookmark pointer 122 can be a specific
`memory location indicating a playback starting, point in the
`message content 116 at which the stored message is played
`back when the user subsequently selects the bookmark
`playback feature.
`FIG. 4 is a flow chain 150 illustrating the operation of the
`voicemail system 68. In step 151, the voicemail system 68
`generates an audio user selection menu for a user that has
`called in. The menu can be generated by the user interface
`program 74, executing on the processor 70 to generate a
`synthesized interactive voice response interface using the
`voice playback subsystem RI]. The menu can provide selec-
`tions conventionally associated with voicemail systems, as
`well as selections related to voicemail bookmarking, such as
`play back or deletion of bookmarked voicemail messages.
`In step 158, a user selects the message playback option
`from the menu. This causes the voicemail system to begin
`the playback of stored messages. During message playback,
`the user can enter a command that starts the bookmark set
`subroutine 152. In this subroutine, the system 68 receives a
`bookmark request from the user (step 160). The bookmark
`request can be a predefined sequence of one or more
`touch—tonc entries. Alternatively, the bookmark request can
`be a voiced command by the user and processed by the
`speech recognition subsystem 84. The bookmark request
`causes the voicemail system 68 to record a memory address
`identifying the current location in the stored voice message
`being played back.
`The bookmark request can include a timing offset value
`that defines a warm up period immediately preceding the
`point in time of the message playback at which the book-
`mark is requcstcd. The timing offset causes the bookmarked
`message to be played back starting from the beginning of the
`warm up period. The timing offset can be entered as a
`touch-tone signal defining a period in seconds. For example,
`immediately after entering the touch-tone command for the
`bookmark request, a user could push the digit "7" to indicate
`a timing otfsct of seven seconds, so that upon subsequent
`
`ill
`
`15
`
`30
`
`35
`
`40
`
`45
`
`50
`
`55
`
`60
`
`65
`
`4
`playback of the bookmarked message, the playback will
`begin seven seconds before the point at which the bookmark
`request occurred in the message. Likewise. other digits
`could be pushed to enter other timing ofiset values, e.g., “l"
`for a one second offiset, “2” for a two second offset, and so
`on.
`
`a memory address corresponding to the
`In step 162,
`timing offset value is computed by the voicemail system 68.
`This can be accomplished by detennining the number of
`bytes required to represent a unit time of recorded Voice. The
`bytes per second value can then be multiplied by the timing
`offset value entered by the user to convert the user-entered
`offset value to a corresponding memory address offset value.
`This address offset value can then be combined with the
`memory address corresponding to the request to generate the
`bookmark pointer.
`The bookmark pointer is then stored in the bookmark
`record {step 164). In step 166, a user message indicator
`generated by the voicemail system 68 is updated to indicate
`that the bookmarked message is no longer a new message.
`The message indicator can be a visual indication, such as
`text, displayable on a user terminal unit.
`Other bookmark—related subroutines, specifically the
`bookmark delete and playback subroutines l54—156, can be
`initiated by the user through the menu. Concerning the
`delete subroutine 154, if upon presenting the user menu, the
`voicemail system 68 receives a request to delete a stored
`voice message or bookmark (step 168), the delete bookmark
`subroutine 154 is initiated. The delete request can be entered
`by a user using a touch-tone or a voice command, and can
`specify one or more bookmarks or messages to be deleted.
`Upon receiving the delete message command, any book-
`marks corresponding to the deleted message are likewise
`deleted (step 170) from the DB 72. Similarly, upon receiving
`a delete bookmark command, the corresponding bookmark
`is deleted.
`
`The bookmarked-rnessagc playback subroutine 156
`allows the voicemail system 68 to play back bookmarked
`voicemail messages stored in the DB 72. In step 1'72, the
`voicemail system 68 receives a bookmark playback request.
`The bookmark playback request can be either a touch-tone
`or voice command entered by the user to select a previously
`bookmarked message for playback. The request can specify
`a particular bookmark ID. Upon receiving the bookmark
`playback request,
`the voicemail system 68 retrieves the
`bookmarked message from the voicemail DB 72 and plays
`back the message starting from the position indicated by the
`bookmark pointer. To playback the stored message,
`the
`message content
`is provided to the voice playback sub-
`system 8|], which generates an audio representation of the
`messages to the user terminal.
