  • Patent number: 11182567
    Abstract: A speech translation apparatus includes: an estimator which estimates a sound source direction, based on an acoustic signal obtained by a microphone array unit; a controller which identifies that an utterer is a user or a conversation partner, based on the sound source direction estimated after the start of translation is instructed by a button, using a positional relationship indicated by a layout information item stored in storage and selected in advance, and determines a translation direction indicating input and output languages in and into which content of the acoustic signal is recognized and translated, respectively; and a translator which obtains, according to the translation direction, original text indicating the content in the input language and translated text indicating the content in the output language. The controller displays the original and translated texts on first and second display areas corresponding to the positions of the user and conversation partner, respectively.

  • Patent number: 10945067
    Abstract: An area reproduction method includes converting a sound pressure distribution at each frequency of a reproduced sound from a sound pressure distribution in a frequency domain into a sound pressure distribution in a spatial frequency domain. The reproduced sound is realized on a control line, including a reproduction line in which sound waves emitted from a speaker array including a plurality of speakers arranged intensify with each other, and a non-reproduction line in which the sound waves weaken with each other. The method includes determining a spatial frequency for use in adjustment of the reproduced sound, in the sound pressure distribution in the spatial frequency domain, based on a positional relationship between the speaker array and the control line, and adjusting a sound pressure of the reproduced sound, which is to be output by each of the plurality of speakers using the determined spatial frequency.
