Abstract: Speech information including a speech sound uttered by a user is obtained. A language of the speech sound included in the obtained speech information is recognized. A first determination for determining whether the recognized language is a first language registered to a memory in advance is made. If it is determined as a result of the first determination that the recognized language is the first language, the speech sound is translated into a second language, which is different from the first language.

Abstract: A sound reproduction method is provided. The method includes acquiring ambient sound information that includes voice spoken to a speech dialog system and indicates sound around a speaking person who has spoken the voice. The method also includes separating the ambient sound information into first sound information including the spoken voice and second sound information including sound other than the spoken voice. The method further includes comparing the sound level of the first sound information with the sound level of the second sound information, and reproducing an audio response to the spoken voice, by selecting one of a first reproduction method and a second reproduction method that is different in terms of directivity of reproduced sound from the first reproduction method in accordance with a result of the comparison.

Abstract: To stably illuminate an LED lamp even when an internally-excited electronic transformer is used in the power supply circuit, the full wave of the AC voltage supplied from the power supply circuit is rectified using a current rectifying circuit. When the power supply starts, current flows into a start-assist circuit for a specific period of time. Subsequently, when the fixed current load circuit begins operating, the current will flow into the fixed current load circuit. When the current flows into the LED driver, operation of the fixed current load circuit is stopped by a current-stopping circuit. Because the current flows into the lamp-lighting circuit across the entire voltage output even when an internally-excited electronic transformer is used in the power supply circuit, operation of the internally-excited electronic transformer will not stop and will not become unstable. When the LED is not connected, the fixed current load circuit is stopped.

Abstract: Howling, which occurs when amplifying a target sound collected by a first microphone through an amplification section and outputting the amplified sound as an intensified sound from a loudspeaker, is suppressed using a first and second acoustic signal. A first power spectrum is produced according to the first acoustic signal output from the first microphone collecting a sound. A second power spectrum is produced according to the second acoustic signal of a sound including at least the intensified sound and not including the target sound. Then, the first acoustic signal is filtered based on the first power spectrum, and the second power spectrum to output only an acoustic signal of the target sound to the amplification section.

Abstract: A signal generating section generates a main signal and a noise reference signal. A determining section determines whether a level ratio is larger than a predetermined value. An adaptive filter section generates a signal indicative of a signal component of a target sound included in the noise reference signal generated by the signal generating section, and learns a filter coefficient only when the determining section determines that the level ratio is larger than the predetermined value. A subtracting section subtracts the signal generated by the adaptive filter section from the noise reference signal. A noise suppressing section suppresses a signal component of noise included in the main signal by using the main signal and the noise reference signal after subtraction by the subtracting section.
