An intelligent automated assistant system engages with the user in an integrated, conversational manner using natural language dialog, and invokes external services when appropriate to obtain information or perform various actions. The system can be implemented using any of a number of different platforms, such as the web, email, smartphone, and the like, or any combination thereof. In one embodiment, the system is based on sets of interrelated domains and tasks, and employs additional functionally powered by external services with which the system can interact.

Intelligent Automated Assistant

A virtual assistant uses context information to supplement natural language or gestural input from a user. Context helps to clarify the user's intent and to reduce the number of candidate interpretations of the user's input, and reduces the need for the user to provide excessive clarification input. Context can include any available information that is usable by the assistant to supplement explicit user input to constrain an information-processing problem and/or to personalize results. Context can be used to constrain solutions during various phases of processing, including, for example, speech recognition, natural language processing, task flow processing, and dialog generation.

Using context information to facilitate processing of commands in a virtual assistant

Systems and methods for creating, modifying, interacting with and playing music are provided, particularly systems and methods employing a top-down process, where the user is provided with a musical composition that may be modified and interacted with and played and/or stored (for later play). The system preferably is provided in a handheld form factor, and a graphical display is provided to display status information, graphical representations of musical lanes or components which preferably vary in shape as musical parameters and the like are changed for particular instruments or musical components such as a microphone input or audio samples. An interactive auto-composition process preferably is utilized that employs musical rules and preferably a pseudo random number generator, which may also incorporate randomness introduced by timing of user input or the like, the user may then quickly begin creating desirable music in accordance with one or a variety of musical styles, with the user modifying the auto-composed (or previously created) musical composition, either for a real time performance and/or for storing and subsequent playback. The graphic information preferably is customizable by a user, such as by way of a companion software program, which preferably runs on a PC and is coupled to the system via an interface such as a USB port. A modified MIDI representation of music is employed, preferably, for example, in which musical rule information is embedded in MIDI pitch data, and in which sound samples may be synchronized with MIDI events in a desirable and more optimum manner. The system architecture preferably includes a microprocessor for controlling the overall system operation. A synthesizer/DSP preferably is provided in order to generate audio streams. Non-volatile memory preferably is provided for storing sound banks. Preferably removable non-volatile storage/memory is provided to store configuration files, song lists and samples, and optionally sound bank optimization or sound bank data. A codec preferably is provided for receiving microphone input and for providing audio output. A radio tuner preferably is provided so that output from the radio tuner may be mixed, for example, with auto-composed songs created by the system, which preferably includes a virtual radio mode of operation.

The method includes the steps of reproducing in the vicinity of each of a plurality of users, programs from one of a plurality of broadcast stations (601); recording upon command by a user, an identification of a station and a time of a program on the station for which supplemental information is desired by the user (609); entering the recorded station identification and time into one of a plurality of information exchange terminals (607); coupling the information exchange terminal to the information depository to transmit information therebetween (162); and identifying a correspondence between the entered station identification and time and a program in a station log to obtain the desired supplementatl information.

Apparatus and methods for accessing information relating to radio and television programs

A method and apparatus are provided for building an intelligent automated assistant. Embodiments of the present invention rely on the concept of “active ontologies” (e.g., execution environments constructed in an ontology-like manner) to build and run applications for use by intelligent automated assistants. In one specific embodiment, a method for building an automated assistant includes interfacing a service-oriented architecture that includes a plurality of remote services to an active ontology, where the active ontology includes at least one active processing element that models a domain. At least one of the remote services is then registered for use in the domain.

A plurality of blocks of waveform data are stored in a memory, which also stores, for each of the blocks, synchronizing information representative of a plurality of cycle synchronizing points that are indicative of periodic specific phase positions where the block of waveform data should be synchronized in phase with another block of waveform data. Two blocks of waveform data (e.g., harmonic and nonharmonic components) are read out from the memory, along with the synchronizing information. On the basis of the synchronizing information, the readout of two blocks of waveform data is controlled using the synchronizing information. There is stored, for each of the blocks, at least one piece of synchronizing position information indicative of a specific position where the block should be synchronized with another block, and the readout of the individual blocks of waveform data is controlled so that the blocks are synchronized with each other using the synchronizing position information.

Apparatus and method for synthesizing a plurality of waveforms in synchronized manner

In each of terminal devices, there is stored user profile information on the corresponding device. The user profile information includes data identifying the user, type and name of the device, information regarding a CPU, memory and operating system (OS) provided in the device, and information regarding various data and program stored in the device. When desired musical information data is to be downloaded from a host computer, a request for downloading optimum data is sent to the host computer. This permits efficient loading of data most suitable for system conditions. When data or program is to be loaded from a recording medium, such as a CD-ROM, rather than a communication network, efficient loading is permitted in a similar manner.

Musical information processing system with automatic data transfer

In a storage section, there are stored special connecting waveform data for connecting between at least two notes to be generated in succession. The special connecting waveform data contain only a waveform of a succeeding-note region of a waveform connecting portion which is provided for a continuous transition between the at least two notes and which is divided into a preceding-note region and the succeeding-note region. When a connecting tone is to be generated for connecting between two notes in accordance with acquired performance information, a tone waveform connecting between waveforms of the two notes is generated using the special connecting waveform data. With such arrangements, the waveform data of the succeeding-note region are read out without waveform data of the preceding-note region being read out, so that it is possible to reduce a time required for transition from a preceding note to a succeeding note. Thus, in the connecting portion for continuously connecting between tones with no break therebetween, a tone can be synthesized with high quality without involving a tone generating delay in the succeeding note.

Tone synthesis apparatus and method

A method is designed for selectively transferring sound data representative of waveforms of various musical sounds from a first storage device to a second storage device. The first storage device stores the sound data accessibly at a first access rate. The second storage device caches the sound data accessibly by a processor at a second access rate faster than the first access rate for instantly providing sound data representative of a target waveform of a musical sound to be processed by the processor. The method carries out the steps of receiving timbre specification information which specifies a timbre of the musical sound, predicting sound data representative of candidate waveforms matching the specified timbre and possibly containing a target waveform, and transferring the predicted sound data from the first storage device to the second storage device for caching so that the processor can hit the target waveform among the cached candidate waveforms.

Music sound synthesis with waveform caching by prediction

In a memory, there are prestored shot-tone-related rendition style modules, each integrally including attack and release waveforms, in addition to attack-, release-, body- and joint-related rendition style modules. When two or more rendition style modules are to be time-serially combined, a shot-tone-related rendition style module is selectively assigned to a tone corresponding to a predetermined rendition style and allotted to a time axis. Then, a waveform is synthesized in accordance with the thus-allotted shot-tone-related rendition style module. Such arrangements permit production, with ample controllability, a high-quality waveform of a characteristic tone faithfully reflecting a predetermined rendition style having rendition styles of attack and release portions closely related each other, which was hitherto impossible.
