    专利说明:

    The invention relates to an apparatus for assisting speech and / or auditory training after cochlear implantation by visually feeding speech back to a rehabilitative patient. The device according to the invention is further distinguished by the fact that it can be used in the everyday environment of a user.
    In Germany alone, about 3,000 to 4,000 patients are treated annually with a cochlear implant (also referred to below as "CI"). A CI (DE 10 2005 049 507 A1) essentially consists of two subassemblies, a subassembly hereinafter referred to as the cochlear module, which is arranged externally on the scalp of a patient and an assembly, the actual implant, which is surgically inserted below the scalp ,
    A cochlear module typically includes a microphone, a microprocessor and a transmitter coil. The microphone is for detecting an acoustic signal, which is supplied to the microprocessor and converted by the microprocessor into a multi-channel, digital signal. By means of the transmitting coil, the multi-channel, digital signal is transmitted through the scalp to a recipient of the implant and forwarded by the receiver to a multi-channel electrode. The pulse-shaped signals conducted into the multichannel electrode stimulate the nerve structures of the cochlea. In this way, the auditory nerve receives the signal and sends it to the hearing center in the brain.
    With the advent of the Cl operations, first of all deaf-born children were cared for, which in this way enabled hearing in the first place. Meanwhile, about 60% of CI restorations are for patients who, due to their severe hearing loss, can not achieve a sufficient understanding of speech with conventional hearing aids. This also includes congenitally hard-of-hearing patients who, due to the progression of their disease, also no longer benefit from conventional hearing aids. Based on the peripheral as well as the central deficits in sound / speech processing acquired during deafness, patients after cochlear implantation require months or years of speech perception rehabilitation. This rehabilitation is currently taking place in a repeated inpatient training, where patients receive visual feedback on speech. The disadvantage here is that a patient can perform this training only in designated therapy centers.
    There are also disclosed other devices and methods incorporating modern technology by which speech and / or hearing can be trained after cochlear implantation.
    The German Hearing Center Hannover, for example, an Android-based application software (hereinafter referred to as App) with the name "hearing training for CIs" known, by means of which hearing after a cochlear implantation can be trained. In this case, an Android device, such as a smartphone or tablet PC, is connected with Cl patients by means of a suitable and approved cable and played by means of the app installed on a smartphone consonant tests or one-, two- or three-syllable word tests. You can set an auditory threshold as minimum volume and a maximum volume used by the program. The disadvantage here is that speech can not be trained by means of such a device.
    Another Android app called "Captioning on Glass" was developed by the Georgia Tech Research Corporation for understanding between two people, at least one of whom may be hearing impaired. By means of this app, an Android-based smartphone and a well-known under the term "Google Glass" glasses display (US 9,195,067 B1) linked together. By means of the microphone of the smartphone, the sound waves of the speech of a person are received and the received acoustic speech signal is converted by means of a processor of the smartphone into a signal with which the spoken text can be visually displayed. This signal is then sent from the smartphone to the glasses and projected with the help of these glasses of the objectified in the text text in the field of view of the glasses wearing second person. The disadvantage here is that the microphone must be kept very close to the mouth of a speaking person when speaking to capture as little noise as possible, which is why this device is only suitable for a limited number of everyday situations.
    The invention is therefore the technical problem of providing a device for voice and / or hearing training after a CI implantation, by means of which the disadvantages of the prior art can be overcome. In particular, the device should shorten the total rehabilitation period of a patient after a CI implantation, thereby reducing the personnel expenditure and, above all, be usable in the everyday environment of the patient.
    The solution of the technical problem results from objects with the features of claim 1. Further advantageous embodiments of the invention will become apparent from the dependent claims.
    A device according to the invention for assisting speech and / or hearing training after a cochlear implantation comprises at least a first processor for converting a first signal containing a speech information into a visual signal containing the speech information and a display element with which the text of the speech information can be accessed visual signal is reproducible.
    Another component of a device according to the invention is a cochlear module. This comprises a microphone for detecting an acoustic signal containing a speech information; at least one second processor for converting the acoustic signal containing the speech information into one of
    A digital signal containing voice information and a first transmitter for transmitting the digital signal containing the voice information. In this case, the first transmitter may comprise that transmitter coil, by means of which the digital signals generated by the processor of a cochlear module are transmitted to the receiver of a cochlear implant below the scalp. Alternatively, the first transmitter can also be designed as an additional, separate transmitter.
    A device according to the invention also includes a first receiver for receiving the digital signal containing the voice information, which can be supplied to the first processor as a first signal.
    By means of a device according to the invention thus an acoustic speech signal, which is detected with the microphone of a cochlear implant, fed back visually as text to the person wearing the cochlear implant, thereby hearing one's own language and the language of other people as well as the own speech of a Cl Patients can be trained.
    In one embodiment, the first receiver, the first processor, and the display element are components of one and the same device. Such a device can be designed, for example, as a smartphone or tablet PC. From the sender of the cochlear module, the digital signals containing a voice information are sent, for example by means of the Bluetooth or Wifi standards to the smartphone or the tablet PC, converted into a processor of the smartphone or tablet PC in a visual signal and on the display of the smartphone or tablet PC as text. Application software, by means of which an auditory speech signal can be converted into a visual text signal, is known and can be installed on a smartphone or on a tablet PC.
    In an alternative embodiment, the first receiver and the first processor are components of a first device and the display element is part of a second device. In this case, the first device comprises a second transmitter for transmitting the visual signal and the second device comprises a second
    Receiver for receiving the visual signal. The first device may be designed, for example, as a smartphone or tablet PC, and the second device may include a projector or a display that does not belong to the smartphone or tablet PC. The display can be designed as a glasses display, as it is known for example under the name "Google Glass".
    In one embodiment of the invention, the second device embodied as a spectacle display has at least one optical element by means of which the text displayed on the spectacle display can be enlarged in the viewing area of a person wearing the spectacle display.
    It should be noted that the term "glasses display" used in the description of the invention is not limited to a glasses display known as "Google Glass", but rather includes all known display elements which are arranged in the vicinity of a person's eye and with which an image Video or text can be faded in or projected into the person's field of view.
    The signal transmission from the first transmitter to the first receiver and / or from the second transmitter to the second receiver can take place, for example, by means of the Bluetooth or Wifi standard, wherein a processor of the first device can store an app with which the signal exchange between cochlear module, first device and second device as well as the conversion of signal exchange of signals involved is controllable.
    The invention will be explained in more detail below with reference to a preferred embodiment. 1 and 2 show one and the same inventive device, wherein in Fig. 1, only the components of a device according to the invention are shown schematically and in Fig. 2, some components of the individual components are shown in a block diagram.
    A device according to the invention according to the preferred embodiment comprises three separate components, a cochlear module 10, as a
    Smartphone or tablet PC formed first means 20 and designed as a glasses display second device 30th
    By means of a microphone 11 of the cochlear module 10, an acoustic signal containing a voice information is detected and forwarded to a processor 12. Processor 12 converts the acoustic signal into a digital signal containing the voice information, which is transmitted by means of a first transmitter 13 to a first receiver 21 of the first device 20. The first receiver 21 supplies the digital signal to a processor 22, by means of which the digital signal is converted into a visual signal containing the speech information. The visual signal containing the speech information is then sent by means of a second transmitter 23 of the first device 20 to a second receiver 31 of the second device 30 and fed there to a display element 32 formed as a display, on which the text of the speech information is displayed.
    The second device 30 embodied as a spectacle display further comprises an optical element, not shown in FIGS. 1 and 2, by means of which the text displayed on the display element 32 is projected enlarged into the field of vision of a person wearing the spectacle display. Such optical elements are common components of known eyewear displays.
    When using a device according to the invention, the cochlear module 10 is usually fastened in the vicinity of an ear by means of a magnet which adheres to the implant located below the scalp. A first device 20 embodied as a smartphone can be worn within a pocket of the clothing of a patient and a second device 30 embodied as a glasses display can be worn as glasses. This leaves the hands of a CI patient free, so that a device according to the invention is suitable for everyday use. This allows a faster learning success in the Cl rehabilitation phase and a shortening of the total rehabilitation time for a patient. A CI rehabilitant no longer relies on voice and / or auditory training at a specialized training center, which can reduce staffing costs, rehabilitation costs, and patient travel costs.
