International Classification:

H04W 4/00

US Classification:

455466, 455564, 4555501, 4554121, 455566

Abstract:

Various embodiments are directed to improved message addressing techniques. In one embodiment, a computing device may comprise a messaging client arranged to receive an input sequence of alphabetic or alphanumeric characters as a destination of an outbound message. The messaging client may recognize that the input sequence represents a mnemonic short code and may automatically generate a common short code comprising a sequence of numeric digits associated with the mnemonic short code. The messaging client may display both the input sequence comprising the mnemonic short code and the common short code and enable the outbound message to be sent using the common short code as the destination. Other embodiments are described and claimed.

Abstract:

A computing device is configured to receive an incoming communication from another computing device. The incoming communication may be for purpose of initiating a voice-exchange session. In response to receiving the incoming call, the computing device may identify or determine a message identifier of the other computing device. The message identifier is determined based at least in part on data provided with the incoming communication. The computing device may programmatically address a message to the other computing device using the message identifier determined from the incoming communication.

International Classification:

H04Q 7/22

US Classification:

4554121, 455566

Abstract:

Techniques involving messaging applications are disclosed. For example, an apparatus may include a communications interface module and a messaging module. The communications interface module may receive an incoming message of a conversation thread that is originated by a remote device. The incoming message includes a text portion and an attached media item. The messaging module automatically outputs the incoming message to a user interface in an output format. This output format includes both the text portion and content of the attached media item. The attached media item may be of various types. Examples of media items include video files, audio files, image files, resource locators, and application files. The embodiments, however are not limited to these examples.

Filed:

Appl. No.:

09/871487

Inventors:

Zhenyu Liu - Pleasanton CA, US
Lang Chen - Fremont CA, US

International Classification:

H04M001/64

US Classification:

379/088010

Abstract:

A voice activation system for a home or office computer allows a user at a remote location to telephone the computer. A modem or other voice hardware for the computer provides a voice signal from the user to a voice activation system that analyzes the voice signal. When the voice activation system recognizes spoken commands in the voice signal, the voice activation system activates procedures according to the spoken command. One procedure in a system that uses the analog voice signal on a telephone line for voice and data hangs up on the user, contacts a dial-up service, downloads voice or e-mail messages from the dial up service, and the calls the user back. Another procedure accesses data such as a telephone number list stored in the computer and converts the data into a voice signal sent to the user at the remote location. With this system, the user can remotely access a computer and retrieve e-mail, voice mail, telephone numbers, and other information without special hardware such as a portable computer and can conduct the remote access without the need for hand touch.

Appl. No.:

09/972308

Inventors:

Lang Chen - Fremont CA, US
Michael Yeung - Fremont CA, US
Zhenyu Liu - Pleasanton CA, US

International Classification:

G10L019/12

US Classification:

704/223000

Abstract:

Voice processing methods and circuits use bandpass filters and energy detectors to determine the energy in frequency channels of a voice signal. A bit array having a horizontal direction corresponding to the channels and a vertical direction corresponding to time provides a representation of the voice signal that can be stored during training and compared to other bit arrays during voice recognition. One comparison method compares horizontal lines of bit arrays using a position-weighted K factor. A segmentation process divides arrays into segments to better identify corresponding lines in arrays. Corresponding lines can also be selected in segments using an alternating top-down/bottom-up best match process. When this comparison finds a matching array, the match is confirmed if match result is significantly better than a match result for a bit array corresponding to different voice command and if vertical checking confirms the match. Thresholds indicating horizontal and vertical matching arrays and the required gap between the match results of different commands can be set according to the desired voice recognition sensitivity.

International Classification:

G09B 3/00

US Classification:

434350000, 434362000

Abstract:

A teaching system provides explanatory materials, examples, and problems on an interactive basis and adapts to the student. The system can generate random questions for presentation to the student as multi-step examples or practice problems. The student's answers during each step of a multi-step practice problem can be evaluated to identify weaknesses. Identified weaknesses can be remedied by presenting additional explanations, providing additional practice problems, and revisiting the weaknesses by inserting practice problems of the identified type into the student's subsequent lessons. The system can also adapt adjusting the speed or number of steps presented according to the student's performance. The system can further provide detailed analysis or diagnosis of the student's performance that can be communicated to teachers and/or parents for use in other teaching environments. The teaching system when embodied in a web site further provides communication among students, teachers, and parents.
