A semantic tagging method may add context to a sentence in order to increase search efficiency. Regardless of an author's writing style, translating semantic concepts into tags may increase search efficiency. Automatic semantic tagging of documents may allow semantic search and reasoning. Text for semantic tagging may include an email, a website chat room, an internet forum, or a text message. Additional texts may include aggregating general consensus of an emailed topic across multiple emails, whether in the same email chain or separate emails. To increase search efficiency, the analysis of prior communications within the body of text may comprise analyzing structured contextual information to facilitate with homophora resolution. The structured contextual information may include at least one of a sender email address, one or more recipient email addresses, a subject field, a message date and time stamp, and an attachment title.

An audio signal encoding and decoding method, an audio signal encoding and decoding apparatus, a transmitter, a receiver, and a communications system, which can improve encoding and/or decoding performance. The audio signal encoding method includes dividing a to-be-encoded time domain signal into a low band signal and a high band signal; encoding the low band signal to obtain a low frequency encoding parameter; calculating a voiced degree factor, and predicting a high band excitation signal; weighting the high band excitation signal and random noise using the voiced degree factor, so as to obtain a synthesized excitation signal; and obtaining a high frequency encoding parameter based on the synthesized excitation signal and the high band signal. Technical solutions in the embodiments of the present invention can improve an encoding or decoding effect.

Embodiments of the present application proposes a frequency envelope vector quantization method and apparatus, where the method includes: dividing N frequency envelopes in one frame into N1 vectors; quantizing a first vector in the N1 vectors by using a first codebook, to obtain a code word corresponding to the quantized first vector, where the first codebook is divided into 2.sup.B1 portions; determining, according to the code word corresponding to the quantized first vector; determining a second codebook according to the codebook of the i.sup.th portion; and quantizing a second vector in the N1 vectors based on the second codebook. In the embodiments of the present application, vector quantization can be performed on frequency envelope vectors by using a codebook with a smaller quantity of bits. Therefore, complexity of vector quantization can be reduced, and an effect of vector quantization can also be ensured.

A system comprising at least one processor configured to perform: receiving a first request to access a first user profile of a first user from a first device configured to execute a first virtual assistant to interact with the first user; in response to receiving the first request, providing the first device with access to information in the first user profile so that the first virtual assistant is able to customize, based on the accessed information, its behavior when interacting with the first user; receiving a second request to access the first user profile from a second device configured to execute a second virtual assistant to interact with the first user; and in response to receiving the second request, providing the second device with access to the information so that the second virtual assistant is able to customize, based on the accessed information, its behavior when interacting with the first user.

Methods and apparatuses are provided for controlling an electronic device that includes a plurality of microphones configured to receive voice input, a storage unit configured to store a sound recording file, and a display unit configured to visually display speaker areas of individual speakers when recording a sound or playing a sound recording file. The electronic device also includes a control unit configured to provide a user interface relating a speaker direction to a speaker by identifying the speaker direction while recording the sound or performing playback of the sound recording file, and to update at least one of speaker information, direction information of a speaker, and distance information of the speaker through the user interface.

According to an embodiment, an information processing apparatus includes a storage unit, a detector, an acquisition unit, and a search unit. The storage unit configured to store therein voice indices, each of which associates a character string included in voice text data obtained from a voice recognition process with voice positional information, the voice positional information indicating a temporal position in the voice data and corresponding to the character string. The acquisition unit acquires reading information being at least a part of a character string representing a reading of a phrase to be transcribed from the voice data played back. The search unit specifies, as search targets, character strings whose associated voice positional information is included in the played-back section information among the character strings included in the voice indices, and retrieves a character string including the reading represented by the reading information from among the specified character strings.
