To enable a patron of a venue attending a performance to feel as if he or she is ‘front and center’ even if located much farther away or angled from a stage of the venue, system and methods that enhance audio quality of audio signals especially over the voice frequency spectrum to generate a processed audio signal including an increased voice frequency spectrum are provided. The processed audio signal may be communicated to a receiving system with a headset or other transducer (e.g., loudspeakers) that allows for ambient sounds to be heard by a patron and for the patron to control volume of the processed audio signal, thereby mixing the processed audio signal with the ambient sounds. The receiving system may be rented and an operator may control usage for both performance or long-term rentals using various control features of the processed audio signals and / or receiving system.

To provide a voice processing technique capable of further clarifying voice as compared with a related art.SOLUTION: A voice processing device includes: a voice signal generation part (11) that generates a first voice signal (x1) and a second voice signal (x2) having spectra equal to each other from a voice signal representing speech; a filter (13) that removes at least a first frequency component equal to or lower than a predetermined first frequency from the first voice signal; a synthesis part (14) that adds and synthesizes the first voice signal from which the first frequency component has been removed and the second voice signal to generate a synthesized voice signal; and a correction signal generation part (12) that generates a phase correction signal (p) on the basis of the second voice signal. The filter includes an operational amplifier (132a) configured to amplify the first voice signal, the operational amplifier is configured to input the first voice signal to an inverting input terminal, and when a phase correction signal is input to a non-inverting input terminal, the filter outputs the first voice signal whose phase is corrected so as to approach the phase of the second voice signal.SELECTED DRAWING: Figure 4

To provide a voice processing device for enabling a hearing-impaired person to easily hear voice without using an auxiliary device by allowing an utterer to use the auxiliary device.SOLUTION: A portable voice processing device (1) includes: a voice processing unit (10) for executing voice processing to clarify voice with respect to a voice signal supplied from a microphone (21) connected to a support member (24) by which the microphone is positioned close to the mouth of a user; a speaker (22) for converting the voice signal after the execution of the voice processing into voice; and a housing for storing the voice processing unit (10).SELECTED DRAWING: Figure 2

An in-ear audio transducer such as a single earphone or a pair of earphones produces audio which accounts for frequency detected hearing impairment and auditory masking conditions spanning frequencies expected to be encountered by the user, thereby improving auditory perception without having to increase overall volume as much as in the prior art. The audio transducer(s) communicates with an audio base unit configured to output modified multichannel digital audio data. The in-ear audio transducer element has a processing unit, a plurality of transducer amplifiers and a plurality of acoustic elements.

A communication system for transmitting sound from a speaker to one or more listeners comprises a microphone (12, fig.1) configured to capture sound from the speaker (1. Fig.1) and at least one personal audio output device 18 respectively configured to be worn by the listeners (3, fig.1). Each personal audio output device is in operative communication with the microphone to receive the captured sound therefrom. The respective audio device comprises a housing 20 configured to be worn by the respective listener; a speaker assembly 22 arranged to be located adjacent ears of the respective listener for emitting sound to the listener’s ears; a captured sound module configured to output a first sound signal including the sound from the microphone; a sound generation module 28 operatively connected to an audio source 54 storing one or more prerecorded audio files 56, and configured to output a second sound signal; and a mixing module 60 configured to combine the first and second sound signals and output the mixed sound to the speaker assembly. The system is intended to help neuro-diverse users to focus in an environment with competing noises e.g. a classroom-like or public address-like setting, or on a particular speaker.

A display device according to an embodiment of the present invention may comprise: a speaker; and a controller for transmitting a sound source to the speaker, receiving information including a plurality of hearing loss amplitudes of the user for the plurality of frequencies, respectively, comparing each of the plurality of hearing loss amplitudes with a first reference amplitude to obtain an inaudible frequency among the plurality of frequencies, and transmitting the inaudible frequency to the speaker. The hearing loss amplitude of the inaudible frequency is greater than or equal to the first reference amplitude, and a compensated sound resource obtained by compensating the inaudible frequency among the frequencies constituting the sound source is output to the speaker.

Provided is speech processing technology capable of making speech clearer than before. The present invention comprises: a speech signal generation unit (11) that generates a first speech signal (x1) and a second speech signal (x2) having mutually equal spectra from a speech signal representing speech; a filter (13) that at least removes, from the first speech signal, a first frequency component that is less than or equal to a prescribed first frequency; a synthesis unit (14) that generates a synthesized speech signal by adding and synthesizing the first speech signal from which the first frequency component has been removed and the second speech signal; and a correction signal generation unit (12) that generates a phase correction signal (p) on the basis of the second speech signal. The filter has an operational amplifier (132a) that amplifies the first speech signal. The operational amplifier is configured such that the first speech signal is input to an inverting input terminal, and in response to input of a phase correction signal to a non-inverting input terminal, the first speech signal that has been corrected so that the phase approaches the phase of the second speech signal is output.
