Methods and systems are provided for generating automatic program recommendations based on user interactions. In some embodiments, control circuitry processes verbal data received during an interaction between a user of a user device and a person with whom the user is interacting. The control circuitry analyzes the verbal data to automatically identify a media asset referred to during the interaction by at least one of the user and the person with whom the user is interacting. The control circuitry adds the identified media asset to a list of media assets associated with the user of the user device. The list of media assets is transmitted to a second user device of the user.

A device control method includes acquiring voice information, obtaining a spoken command indicating a control instruction as to a device based on the acquired voice information, identifying speaker information relating to a speaker which has uttered the acquired voice information, based on the acquired voice information, identifying, out of a plurality of devices, a device to be controlled, based on the spoken command and the speaker information, and controlling the identified device to be controlled.

Presentation of a recommendation to a user for individual processing of audio tracks in a digital audio workstation. Training audio tracks are provided to a human sound mixer and responsive to the training audio tracks individually processed training audio tracks are received from the human sound mixer. The training audio tracks and the individually processed training audio tracks are input to a machine to train the machine. Audio processing operations are output from the trained machine and stored in a record of a database.

Provided are a method and apparatus for encoding and decoding an audio signal. According to the present application, a signal of a high frequency band above a preset frequency band is adaptively encoded or decoded in the time domain or in the frequency domain by using a signal of a low frequency band below the preset frequency band. As such, the sound quality of a high frequency signal is not deteriorate even when an audio signal is encoded or decoded by using a small number of bits and thus coding efficiency may be maximized.

A voice processing device includes a first sound collecting unit for generating a first voice signal; a human-body vibration obtaining unit for generating a human-body vibration signal; a first distance calculating unit for calculating a ratio in power or amplitude between the human-body vibration signal and the first voice signal and for calculating a first distance from the first sound collecting unit to a sound source in accordance with the ratio and distance estimation information; a second distance calculating unit for calculating, for each of a plurality of frequencies, a second distance from the first sound collecting unit to a sound source which produces a component of a frequency of a first frequency signal; a gain determining unit for determining, for each of the plurality of frequencies, a gain based on a comparison result between the first distance and the second distance.

Techniques for adaptive processing of media data based on separate data specifying a state of the media data are provided. A device in a media processing chain may determine whether a type of media processing has already been performed on an input version of media data. If so, the device may adapt its processing of the media data to disable performing the type of media processing. If not, the device performs the type of media processing. The device may create a state of the media data specifying the type of media processing. The device may communicate the state of the media data and an output version of the media data to a recipient device in the media processing chain, for the purpose of supporting the recipient device's adaptive processing of the media data.
