An acoustic feature estimation method is an acoustic feature estimation method for estimating an acoustic feature of a space and includes acquiring data on the space, estimating situations in the space in accordance with the acquired data, correcting a provisional value of the acoustic feature in accordance with the estimated circumstances, and outputting the corrected provisional value.

Acoustic feature estimation method, acoustic feature estimation system, recording medium, and rendering method

An information processing method includes: obtaining spatial information indicating a shape of a virtual space including an obstacle and a sound source object that emits a predetermined sound; obtaining position information indicating a position and an orientation of a user in the virtual space; and generating an acoustic virtual environment by determining, based on the position and the orientation of the user and a position of the obstacle in the virtual space, a position of a virtual reflection surface off which the predetermined sound is reflected in the virtual space.

Information processing method, recording medium, and information processing system

An acoustic reproduction method includes: acquiring a first audio signal corresponding to an ambient sound that arrives at a listener from a first range in a sound reproduction space and a second audio signal corresponding to a target sound that arrives at the listener from a point in the sound reproduction space; acquiring direction information about the listener; performing, when a back range of the listener is determined to include the first range and the point based on the direction information, correction processing such that the first range does not overlap the point when the sound reproduction space is viewed in a predetermined direction; and mixing at least one of the first audio signal or the second audio signal and outputting the at least one thereof to an output channel.

Acoustic reproduction method, recording medium, and acoustic reproduction device

An acoustic reproduction method includes: localizing a first sound image at a first position in a target space in which a user is present; and localizing, at a second position in the target space, a second sound image that represents an anchor sound for indicating a reference position.

Acoustic reproduction method, acoustic reproduction device, and recording medium

A sound reproduction method includes: obtaining a first audio signal indicating a first sound which arrives at a listener from a first range and a second audio signal indicating a second sound which arrives at the listener from a predetermined direction; when the first range and the predetermined direction are determined to be included in a second range which is a back range relative to a front range in the direction that the head part of the listener faces, performing a correction process on at least one of the first audio signal or the second audio signal so that intensity of the second audio signal becomes higher than intensity of the first audio signal; and performing mixing of the at least one of the first audio signal or the second audio signal, and outputting, to an output channel, the first and second audio signals.

A translation device comprises: a memory that stores first dictionary information including a replacement target term in a first language and a translated word in a second language for the replacement target term in association with each other, and second dictionary information including an alternative term instead of the replacement target term; a controller that replaces the replacement target term included in an input sentence with the alternative term to generate a replaced sentence; and a communication interface that outputs the replaced sentence to an external device and acquires a translation result of the replaced sentence in the second language from the external device. The controller detects a specific character string in the translation result of the replaced sentence acquired from the communication interface, and replaces the detected character string with a translated word associated with the replacement target term in the first dictionary information, to generate a translated sentence.

To provide a bandwidth extension method which allows reduction of computation amount in bandwidth extension and suppression of deterioration of quality in the bandwidth to be extended. In the bandwidth extension method: a low frequency bandwidth signal is transformed into a QMF domain to generate a first low frequency QMF spectrum; pitch-shifted signals are generated by applying different shifting factors on the low frequency bandwidth signal; a high frequency QMF spectrum is generated by time-stretching the pitch-shifted signals in the QMF domain; the high frequency QMF spectrum is modified; and the modified high frequency QMF spectrum is combined with the first low frequency QMF spectrum.

A storage unit stores a target term, a substitute term, a substitute translated term, and a representative term. The substitute translated term is a translation of the substitute term and is expressed in a second language. The representative term indicates a type of the target term and is expressed in the second language. A communication unit acquires a provisional translation that is a translation of a processed sentence from a first external device that has a translation function. When the storage unit does not store a target translated term that is a translation of the target term, a controller replaces the substitute translated term contained in the provisional translation with the representative term to generate a second display-purpose translated sentence, and then causes a display unit to display the second display-purpose translated sentence.

A translation device includes an input unit and a controller. The input unit obtains first text data in a first language. The controller generates second text data in a second language that is a translation of the first text data. The controller further generates first replacement data by replacing a first term, of a predetermined type, contained in the first text data by a parameter, obtains second replacement data, in the second language, corresponding to the first replacement data, and generates the second text data by replacing the parameter contained in the second replacement data by a second term in the second language that is a translation of the first term.

Translation device and translation method

A translation device is configured to translate from a first language into a second language and includes a first language acquisition unit, a polyseme processor, and a first language output unit. The first language acquisition unit acquires a sentence in the first language. The polyseme processor determines whether or not a word in the second language for a word in the first language included in the sentence is a polyseme, and acquires a plurality of candidate meanings for the word in the second language when the word in the second language is determined as a polyseme. The first language output unit outputs the plurality of candidate meanings.

A voice input device includes an input unit, a storage unit, an operation unit, and a controller. The input unit acquires a voice and generates voice data corresponding to the voice. The storage unit stores the voice data inputted from the input unit. The operation unit is operated by a user. The controller determines a voice activity period in which voice recognition is performed on the voice data stored in the storage unit based on a user's operation on the operation unit. Then, upon detecting a predetermined operation on the operation unit made by the user, the controller adjusts the determined voice activity period.

A translation device includes an input unit, a controller, a notification unit, an output unit, and a memory. The input unit inputs an utterance of a speaker to generate utterance data. The controller determines accuracy of a translation result when translated utterance data from the utterance data is obtained. The notification unit notifies the speaker of the determination result of the controller. The output unit outputs a translated utterance according to the translated utterance data. The memory stores dictionary data associating utterance data with translated utterance data. The controller performs translation based on the dictionary data. When the controller determines that the accuracy of the translation result is lower than a predetermined value, the controller controls the output unit not to output the translated utterance, and controls the notification unit to issue a notification regarding the determination result.
