  • Patent number: 8606256
    Abstract: In a method of processing an incoming sequence of one or more DTMF tones at a mobile device, the sequence is decoded to thereby identify any encoded message. Where the decoding does not identify a message, at least applying an error correction algorithm to the sequence to identify a message. Where the algorithm fails to correct the sequence, the sequence is compared to messages currently expected by the mobile device. If a message is not identified, a negative acknowledgement message may be sent. At a server, upon receipt of a negative acknowledgement message, it is determined if a message was sent to the mobile device in a previous pre-determined time window. If so, the message is re-sent. The server repeatedly sends certain messages to a mobile device until an acknowledgement message indicating receipt of the message by the mobile device is received.

    Abstract: A system and method for canceling a message sent to a recipient prior to retrieval by the recipient. A telephone call is received by a network from a calling party who desires to cancel a message left for a recipient through an earlier call from the calling party to the recipient after termination of the earlier call. By mapping the calling party's automatic number identifier (ANI) with at least one call record, a voice mailbox of the recipient may be accessed to determine whether the message has been retrieved by the recipient. If the message is still pending, the calling party is provided with the option to cancel the message. Alternatively, the calling party provides the telephone number from where the earlier call originated to a network server, which looks up the ANI of the originating number and then maps the ANI of that number with the at least one call record to enable the cancellation procedure.

  • Patent number: 6728348
    Abstract: The present invention is a system that uses a limited text input entry device to narrow the possibilities for the selection of a phonetically based name used in a voice dialer. The user enters a DTMF signature of a name using only one key for each letter of the name. The signature is used by a dictionary to generate likely possibilities for the word. The user is asked whether the name is the name entered via playing the name to the user. If the user confirms the choice, the phonetic representation is stored along with a corresponding telephone number. If the played word does not match, a word generator generates additional likely possibilities from the signature. A speech recognizer picks the best representation from the dictionary and generator words based on a spoken version of the name. A first name and last name procedure, in which the first and last name signatures produce separate candidate lists, is used to provide an entry to an address book for voice dialing.

    Abstract: The present invention provides a method and interface for browsing the internet using a telephone circuit having keys for generating DTMF codes. The interface includes a memory and a processor and is coupled to the telephone circuit and display. The interface receives a first DTMF code requesting access to the internet and, in response to the first DTMF code, loads a Web browser in its memory. The interface then receives a second DTMF code from the telephone circuit and converts the second DTMF code into a Web browser command using an interpretation protocol. The Web browser command is then executed using the interface, thereby enabling a user to access the internet via manual operation of the keys of the telephone is circuit.

  • Patent number: 6246983
    Abstract: A multi-user e-mail reader system allows several users to access their e-mail accounts simultaneously and have the e-mail messages played back with speech synthesis. The user navigates through various functional states of the system using either touch-tone keypad commands or optionally voiced commands interpreted by a speech recognizer. Users can send reply e-mail messages without the use of a computer, by invoking the system's text processor. The text processor operates in conjunction with a keypad-to-ASCII conversion mechanism that allows fully punctuated and properly addressed e-mail messages to be composed from the touch-tone phone. Digital audio sound file attachments may be recorded through the telephone handset and attached to an outgoing e-mail message. A system for storing canned messages allows the user to quickly send pre-composed reply messages, either as stored or after editing using the text processor.

  • Patent number: 6236724
    Abstract: A method of generation and detection of acoustic signals carrying alpha-numeric data for reducing the effects of noise and thereby improving signal transmission without the need to boost the power of the signal. In accordance with one aspect of the invention, a special DTMF acoustic signal consisting of a combination of two frequencies will be generated for the representation of a particular alpha-numeric character that will be similar to the standard DTMF tone. The difference between the amplitudes of both frequencies varies during the time of generation of the DTMF tone in such a way that both signals will arrive at a final destination detector, i.e., an interactive voice response board, at least for a portion of the generation time, at a relatively similar amplitude, thereby substantially increasing the probabilities of being recognized as a DTMF signal.
