Abstract: An information processing method includes: obtaining a target distribution indicating a target for sound pressure distribution in a space; obtaining an initial value of a parameter value, the parameter value being a value of an acoustic parameter of the space; executing acoustic simulation using the initial value as the parameter value, to obtain the sound pressure distribution in the space; updating the parameter value to bring the sound pressure distribution obtained closer to the target distribution; and outputting the parameter value updated.

Abstract: A speaker device includes a speaker that outputs sound, a horn that emits sound output from the speaker, and a slit opening that is formed on a front surface of the horn, a vertical side of the slit opening being longer than a horizontal side of the slit opening. It is possible to prevent reflection of unnecessary sound in a vertical direction and enhance sound reproduction performance in a horizontal direction.

Abstract: An area-sound reproduction system is provided that includes a speaker array having a plurality of speakers arranged side by side, a sound collector configured to collect an environment sound in an environment where the area-sound reproduction system is installed, a processor, and a memory having a computer program stored thereon. The computer program causes the processor to execute operations, including adjusting signals that the plurality of speakers are caused to output as reproduced sounds according to a reproduction condition on a control line, and causing the plurality of speakers to output the reproduced sounds.

Abstract: A method is provided for controlling a device used in a speech-recognition system, in which the device captures speech. The method includes determining a presence or an absence of an object in proximity to the device. The method also includes controlling capturing speech or not capturing speech in accordance with the determination. In the method, the capturing of speech is performed using a microphone of the device.

Abstract: Provided is an area reproduction system including a reproduction unit including a speaker array, a processing unit that processes a reproduction sound to be output from each of a plurality of speakers included the speaker array, based on a control line including a reproduction line that strengthens a sound wave radiated from the speaker array and a non-reproduction line that weakens the sound wave, so that an audio beam of a predetermined sound pressure or more is radiated only to the reproduction line, the control line being substantially parallel with the speaker array and being set in a position separated from the speaker array, and a directional angle control unit that adjusts a phase of the reproduction sound so that a radiating direction of the audio beam is deflected by a specified angle, in which each of the plurality of speakers outputs the processed and adjusted reproduction sound.

Abstract: A method is provided for controlling a terminal used in a speech recognition system in which the terminal captures speech, where the captured speech is converted into character strings through speech recognition in the terminal or is transmitted to an external device and is converted into character strings through speech recognition in the external device. The method includes determining a presence or an absence of an object in proximity to the terminal, and specifying a first character string captured by the terminal while it is determined that the object in proximity to the terminal is present. The method also includes specifying a second character string captured by the terminal while it is determined that the object in proximity to the terminal is not present. The method further includes determining a first display form of the first character string and a second display form of the second character string.
