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.

Information processing device to stop the turn off of power based on voice input for voice operation

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 a speech processing apparatus including a word string estimation unit that estimates a word string equivalent to input speech among word strings included in dictionary data, and a calculation unit that calculates, for an element part constituting the word string estimated by the word string estimation unit, a certainty factor in which a content of the element part is equivalent to a content of a corresponding part in the input speech.

Speech processing apparatus, information processing apparatus, speech processing method, and information processing method

There is provided a speech processing apparatus to improve the flexibility of processing regarding speech recognition, the speech processing apparatus including: a determination unit configured to determine how to deal with a recognition result of speech data obtained by a first speech recognizer on a basis of a comparison between a certainty factor of the recognition result of the speech data obtained by the first speech recognizer and a threshold; and a threshold setting unit configured to set dynamically the threshold. The method further comprises using three operation modes where third, second and first modes comprise of three, two and one recognizers respectively, and the threshold in the third mode is lower than the second mode and higher than the first mode.

Speech processing apparatus and speech processing method with three recognizers, operation modes and thresholds

There is provided an information processing device technology that enables an improvement in precision of sound recognition processing based on collected sound information, the information processing device including: a recognition controller that causes a speech recognition processing portion to execute sound recognition processing based on collected sound information obtained by a sound collecting portion; and an output controller that generates an output signal to output a recognition result obtained through the sound recognition processing. The output controller causes an output portion to output an evaluation result regarding a type of sound based on the collected sound information prior to the recognition result.

Information processing device, method of information processing, and program

A music signal processing apparatus includes a frequency spectrum transform unit, a filter, a frequency feature amount generation unit, and a melody feature amount sequence acquisition unit. The frequency spectrum transform unit is configured to transform a music signal into a frequency spectrum, the music signal being a signal of a musical piece containing a part with a melody. The filter is configured to remove a steep peak of the frequency spectrum. The frequency feature amount generation unit is configured to generate, from a signal output from the filter, a frequency feature amount in which a fundamental frequency component of the part is emphasized. The melody feature amount sequence acquisition unit is configured to acquire, based on the frequency feature amount, a melody feature amount sequence that specifies a fundamental frequency of the part at each time.

Techniques of audio feature extraction and related processing apparatus, method, and program

A content reproduction device including: a microphone that collects noise in the surroundings of a casing; a feature amount extractor that extracts a plurality of feature amounts; a distance calculator that calculates an intervector distance between the extracted feature amount vector and a feature amount vector with the same dimensions which is set in advance as a feature amount of a waveform of a music signal; a determinator that determines whether or not music is included in the sounds collected by the microphone; a processor that processes the signal of the sounds collected by the microphone to change the volume or frequency characteristics of the sounds collected by the microphone; and an adder that adds and outputs the signal of the sounds collected by the microphone and the signal of sounds of reproduced content.
