Description

  The present invention relates to a speaker device and a conversation support system, and more particularly to a speaker device and a conversation support system suitable for improving hearing.

  Conventionally, as a technique for processing an audio signal, for example, a technique for improving hearing by assisting a hearing-impaired person in understanding sound.

  Various hearing aids have been proposed as assistive technologies for understanding the voice for the hearing impaired. Hearing aids are sound amplifiers intended to solve hearing problems caused by hearing loss, and are composed of an input unit, an amplification unit, an output unit, a power supply, etc., and amplification is performed electrically or electronically, In addition to expanding the sound, amplification is performed taking into account factors such as sound sensitivity, dynamic range, frequency resolution, time resolution, and directionality. Moreover, unnecessary noise is cut as necessary, and the S / N ratio is improved to make it easy to hear.

  In recent years, digital hearing aids that have become the mainstream can change their characteristics on software, can be easily adjusted, and can be performed immediately. In addition, advanced and complex processing is possible by digital control, and a dramatic improvement in performance of hearing aids has been realized.

  However, hearing aids are effective for listening to sounds emitted in the immediate vicinity because they are put on the ears and listened to by inputting sound, but it is difficult to hear sounds generated from a remote place. There's a problem.

  Hearing aids are designated as managed medical devices (Class II) under the Pharmaceutical Affairs Law in Japan, and are legally regulated. In addition, when using a hearing aid, there is a problem that adjustment (fitting) according to an individual's hearing ability or usage is necessary, and adjustment at a specific store, specialty store, or medical institution is necessary.

  In Patent Document 1, a plurality of sound emission and collection devices connected via a network are provided for the purpose of enabling a hearing-impaired person to listen to various life sounds without having to wear and carry a hearing aid. Proposed sound emission and collection systems have been proposed. In this sound emission and collection system, a sound collection unit that collects sound and outputs a sound signal to the sound emission and collection device, a sound output unit that inputs the sound signal and emits the sound, and a sound collection unit outputs The audio signal is transmitted to another sound emitting and collecting device, and the communication unit that receives the audio signal from the other sound emitting and collecting device, and the audio signal received by the communication unit are input. And a correction unit that performs correction according to the input and inputs the corrected audio signal to the sound output unit.

  With such a configuration, the sound collected by the sound collection unit is transmitted to another sound emitting and collecting device, and the sound received from the other device is corrected according to the auditory characteristics. For example, human auditory sensation has a property that it becomes difficult to hear the high frequency range as compared to the middle and low frequency range as the age increases. In each sound emission and collection device, the corrected sound is emitted, so that the deaf person can listen to various life sounds without having to wear and carry a hearing aid. By these things, according to the technique of patent document 1, a hearing-impaired person can listen to various life sounds, without having to wear and carry a hearing aid.

  In Patent Document 2, for the purpose of making it easier for a hearing-impaired person to hear speech, each speech signal input from a microphone is divided into a consonant region and a vowel region on a time axis, and the consonant region sound and the vowel are separated. A technology that divides the range sound into one or more independent sound frequency bands, processes the consonant range sound and the vowel range independently, and provides them to the hearing impaired, and the consonant range and vowel range A technique for generating and providing a pace signal for adjusting the speed of the talk from the listener side to the speaker corresponding to the sound being repeated for each sound is described.

  As such a configuration, for example, individual deaf persons can perform band settings such that consonant sounds are amplified on the high frequency band side and vowel sounds are not amplified on the high frequency band side. It is possible to make a setting that is easy to hear for the user. Also, by providing the speaker with a pace signal that is most audible to the individual with the hearing loss and having the speaker speak at a speed based on the pace signal, the speaker can hear at the speed that is most audible to the individual with the hearing loss. Can be heard.

  In Patent Document 3, language information data for input speech is generated based on information related to speech recognition of speech input from a speech input device, and character image data for input speech is generated based on the generated language information data. In addition to the technology for displaying on the display device, information on the frequency vs. spectral intensity, level, and magnitude of the input speech (speech feature data) is generated. The color information data for the input voice is generated and the color information data is generated on the display device together with the character image data on a plane having axes representing time and frequency. Describes a technique for displaying the displayed color in accordance with temporal changes.

  The information (sound spectrogram) on the frequency vs. spectral intensity, height, and magnitude of the input speech can convey the speaker's personal characteristics such as gender and emotions. By displaying on the display device together with character information indicating the language and presenting it to the hearing impaired person, the hearing impaired person can understand the content of the speaker, including individual differences and emotions of the speaker.
