AI Technical Summary
Technical Problem
Information terminals, such as smartphones, may mistakenly recognize speech from individuals other than the user, leading to unintended operations.
Method used
An acoustic device equipped with a sound detection unit, a sound separation unit, a sound determination unit, and a processing unit, which uses a machine learning model to register and recognize the voice features of the user, analyze voice commands, and generate signals to execute instructions while canceling noise.
Benefits of technology
The acoustic device effectively suppresses malfunctions in information terminals by ensuring that only registered voice commands are executed, thereby enhancing the precision of speech recognition and reducing noise interference.

Abstract
To provide an acoustic device which suppresses malfunction of an information terminal and can highly precisely recognize voice, an operation method of the device, an information processing system and an information processing method.SOLUTION: An acoustic device 10 includes: a sound detection unit 11 having a function for detecting sound 21; a sound separation unit 12 for separating the sound which the sound detection unit detects into voice and sound other than the voice; a sound determination unit 13 for registering a feature amount of the sound; a processing unit 15 for determining whether or not the feature amount of voice which the sound separation unit separates is the one registered by a machine learning model such as a neural network model, analyzing a command included in the voice if the feature amount of the voice is the one registered, generating a command signal indicating a content of the command and performing processing to cancel sound other than the voice to the sound other than the voice which the sound separation unit separates; a transmission / reception unit 16 for synthesizing the sound having been subjected to processing by the processing unit and sound which an information terminal 22 emits; and a sound output unit 17 for emitting the synthesized sound to the outside of the acoustic device.SELECTED DRAWING: Figure 1
