There is provided a signal processing device that includes a processing unit configured to collect, through a microphone, a mixed sound signal as a mixed sound of a speaker reproduction signal and a target signal, input a first suppression signal resulting from suppression of the speaker reproduction signal from the mixed sound signal by linear processing, the speaker reproduction signal, and the mixed sound signal collected through the microphone, and output a second suppression signal resulting from further suppression of the speaker reproduction signal from the first suppression signal by non-linear processing.

Signal processing device and signal processing method

Provided is a device that includes a user spoken voice extraction unit that extracts a user spoken voice from a microphone input sound. The user spoken voice extraction unit analyzes a sound source direction of an input sound, determines whether the input sound includes an external apparatus output sound on the basis of sound source directions of external apparatus output sounds recorded in a database, and removes a sound signal corresponding to a feature amount, for example, a frequency characteristic of the external apparatus output sound recorded in the database, from the input sound to extract a user spoken voice from which the external apparatus output sound has been removed upon determining that the input sound includes the external apparatus output sound.

Information processing device, information processing system and information processing method

An information processing device presents first information indicating that voice input for the voice operation is possible and second information representing a domain of utterance in which voice operation is possible in response to an occurrence of a predetermined state transition, and performs voice recognition for voice input by a user.

The present technology relates to an information processing device and an information processing method that enable output of information using a more optimal output modal. Provided is an information processing device including a processing unit configured to perform processes of: acquiring apparatus information regarding an output modal for each electronic apparatus; selecting an electronic apparatus having an output modal that outputs information from among a plurality of electronic apparatuses on the basis of the acquired apparatus information; and outputting the information from an output modal of the selected electronic apparatus. The present technology can be applied to, for example, electronic apparatuses such as information apparatuses, video apparatuses, audio apparatuses, or household electrical appliances.

Information processing device and information processing method

Provided is an information processing apparatus that has an utterance function or controls the utterance function. The information processing apparatus includes a sending unit that sends interactive information regarding a voice agent, a receiving unit that receives interactive information regarding another voice, and a control unit that controls an utterance timing of the voice agent on the basis of the interactive information regarding another voice agent received by the receiving unit. The control unit causes utterance by the voice agent to stand by on the basis of the interactive information received from another voice agent. Moreover, the control unit causes the interactive information to be continuously sent during the utterance by the voice agent and during interaction between the voice agent and a user.

Information processing apparatus and information processing method

Compensation accuracy is increased with respect to clip compensation in a case where signals from a plurality of microphones are subjected to an echo cancellation process. A signal processing device according to an embodiment of the present technology includes an echo cancellation unit that performs an echo cancellation process of canceling an output signal component from a speaker on signals from a plurality of microphones, a clip detection unit that performs a clip detection for signals from the plurality of microphones, and a clip compensation unit that compensates for a signal after the echo cancellation process of clipped one of the microphones on the basis of a signal of non-clipped one of the microphones.

Signal processing device, signal processing method, and program

Deterioration of voice extraction performance when positions of a plurality of microphones are changed is prevented. A signal processing device according to an embodiment of the present technology includes a voice extraction unit that performs voice extraction from signals of a plurality of microphones, in which the voice extraction unit uses, when respective positions of the plurality of microphones are changed to positions where other microphones have been present, respective signals of the plurality of microphones as signals of the other microphones. Thus, it is possible to cancel the effect of changing the positions of respective microphones on the voice extraction.

The present technology relates to a voice input device and method that facilitate estimation of an utterance direction. The voice input device includes a fixed part disposed at a predetermined position, a movable part movable with respect to the fixed part, a microphone array attached to the fixed part, an utterance direction estimation unit that estimates an utterance direction on the basis of a voice from an utterer that is input from the microphone array, and a driving unit that drive the movable part according to the estimated utterance direction. The voice input device can be used by installation in, for example, a smart speaker, a voice agent, a robot, and the like.
