Description
Method and apparatus for improving learning
The invention relates a method and an apparatus for remedying auditory defect and enabling an improvement in learning of languages.
Background of the invention
The sense of hearing, hearing problems and individualized auditory stimulation have been studied for a long time. The theoretical premise for individualized auditory stimulation is based on studies carried out in the 1950s, which related to hypersensitivity of hearing. It has been observed that an imbalance of hearing affects the early stages of speech development and learning to read, and also causes psychiatric problems.
For example, the French physician Alfred Tomatis has developed a method wherein low-frequency sounds are filtered out of sound stimuli and the sounds thus processed are used as training exercises in hearing. Many people suffering from learning difficulties have been diagnosed as having an auditory processing disorder and difficulty in hearing.
Auditory cognition disorder, particularly owing to the temporal structure and rapid transience of auditory cues, is often also linked to reading disability. In the observations, auditory processing disorders appear in early childhood as delayed development of language and speech, but problematic features are retained by many people into adulthood, causing leaning difficulties.
One example of an auditory processing disorder is an auditory delay, which results from unsuccessful synchronization in the brain of a sound heard by both ears. When sounds are not synchronized, a sound that has come via one ear is delayed, and in this way essentially affects the language-learning skill of the person.
Known in the art are devices and methods e.g. for solving a stuttering problem. Publication US3101081 describes a device for solving a stuttering problem. The device according to publication US3101081 is
intended to reduce disturbances in lateralization, by means of which device the volume of sound coming into one of the ears is adjusted.
A hearing aid device is also described in publication US2010172506, the aim of which device is to ameliorate a hearing disorder in one of the ears. The device described by US2010172506 functions by means of microphones arranged in two ears. The device thus functions in such a way that the electrical signals produced by the microphones in both ears are combined, and the output sound is consequently repeated on the side with good hearing. The signals produced by the left-hand and right-hand microphones are first combined, and after that the signal produced by the left-hand microphone is delayed for combining both signals.
Also known from publication US201131331 is a solution describing lateralization processing, by the aid of which a system has been made to identify and localize sound signals, even though the temporal receiving of sounds and the height of the sounds can be different between the left and the right ear. The system is arranged to replace only the naturally existing ITD and ILD (Interaural Time Difference/Interaural Level Difference) figures, which are caused by the difference of the locations of the right and left ear on the head towards the sound source.
Another prior art publication US2005095564 describes methods, devices and systems which treat non-stuttering speech and/or language related disorders by administering a delayed auditory feedback signal having a delay of under about 200 ms via a portable device. In certain embodiments of US2005095564 a receiver such as a microphone or transducer receives the sound waves. The transducer produces an analog input signal of sound corresponding to the user's speech. According to the embodiment, the analog input signal is converted to a stream of digital input signals. Prior to conversion to a digital signal, the analog input signal can be filtered by a low pass filter to inhibit aliasing. The cutoff frequency for the low pass filter should be sufficient to reproduce a recognizable voice sample after digitalization. A conventional cutoff frequency for voice is about 8 kHz. US2005095564-document describes that filtering higher frequencies may also remove some unwanted background noise.
It's also known (e.g. from http://tomatislausanne.ch/pages/ english/en_integration_des_langues.html) that different languages have
different frequency ranges where the sound of speech is dominant. E.g. the French use mainly the frequencies between 1000 and 2000 Hz, whereas the British use frequencies ranging from 2000 to 12000Hz. The human ear is designed to pick up a wide range of sound frequencies and perceive an infinite number of rhythms, but in practice, many people can only recognize the sounds and rhythms of their mother tongue. In every part of the world, in every nation, people hear in different ways and this affects ability to learn each other's languages.
By means of the solutions disclosed in prior art the needs of the user and his hearing system cannot be individualized to enable an improvement in learning.
Brief description of the invention
The aim of the solution of the invention is to remedy the deficiencies of prior art and to enable an improvement in learning of languages, e.g. different foreign languages. The invention relates to an apparatus and to a method, by means of which audio signals coming to the ears can be individualized according to the needs of the user. In the apparatus according to the invention the frequency response of the audio signals going to the ears can be adjusted in such a way that frequencies outside the frequency range of human voice of a specific language are filtered out.
In one embodiment of the invention for improving auditory learning in some cases it must be possible to adjust the signals going to both ears individually and in such a way that the sounds coming to both ears would be synchronized. In this embodiment it is possible to compensate the delay in a sound coming to one ear compared to the delay in the sound coming to the other ear.
The method and apparatus according to the invention for remedying an auditory defect comprises receiving an incoming sound signal as an input signal, the incoming sound signal having at least one channel, adjusting the frequency response of the at least one channel of the input signal by filtering out frequencies outside the frequency range of human voice of a specific language and outputting the filtered signal of at least one channel.
In the apparatus according to the invention the audio channels, which are separated from each other, can be adjusted independently of each other or in some situations some adjustments can be made jointly to both channels. In the device according to the invention there can be adjustments to the frequency response, delay and/or amplification of the final signal.
The solution of the present invention has an advantage that it can enable an improvement in learning of languages, e.g. different foreign languages when frequencies outside the frequency range of human voice of a specific language are filtered out.
People usually have a personal frequency range to which the brain of the person is used to. The brain emphasizes articulation and this personal frequency range based on qualities of mother tongue of the person. At the beginning, when a person studies foreign language, they have a strong accent based on their mother tongue when pronouncing the foreign language. In one embodiment of the invention the solution of the invention amplifies typical frequencies used in the foreign language. At the same time it's also possible to attenuate typical frequencies used in the mother tongue of the person. This helps the person to hear new frequencies of the new foreign language and thus helps the person to learn new languages and reduces the effects of the mother tongue to the learning of new language.
Brief description of the figures
In the following, the invention will be described in more detail by the aid of some example embodiments with reference to the drawings, wherein,
Fig. 1 presents known frequency ranges of human voice of different languages.
Fig. 2 presents a method of one embodiment of the invention, and
Fig. 3 presents, as a block diagram, a solution according to one embodiment of the invention.
Detailed description of the invention
Figure 1 presents known frequency ranges of human voice of different languages. As can been seen from the Figure 1 different languages have different frequency ranges where the sound of speech is dominant. According to different sources the French use mainly the frequencies 125 - 500 Hz and 1000 - 2000 Hz, the British use frequencies ranging from 2000 to 12000 Hz, the German use mainly frequencies between 125 and 3000 Hz, the Spanish use mainly frequencies 125 - 500 Hz and 1500 - 3000 Hz, the Italians use mainly frequencies between 500 and 3000 Hz , the US-English speakers use mainly frequencies between 500 and 3000 Hz or 1000 - 4000 Hz, the Chinese use mainly frequencies between 125 and 2000 Hz, the Dutch use mainly frequencies between 125 and 4000 Hz, the Japanese use mainly frequencies between 125 and 1500 Hz, the Portuguese use mainly frequencies between 250 and 4000 Hz and the Russian use mainly frequencies between 125 and 12000 Hz in their voice.
Fig. 2 presents a method of one embodiment of the invention. In the method of the invention an incoming sound signal is received as an input signal. After that the frequency response of the at least one channel of the input signal is adjusted by filtering out frequencies outside the frequency range of human voice of a specific language. After filtering out frequencies outside the frequency range of human voice of a specific language, the filtered signal of at least one channel is outputted.
In one embodiment of the invention a language can be selected from the apparatus e.g. by the user from the user interface. The filter to be used to filter out frequencies outside the frequency range of human voice of a specific language is then selected based on the language selection.
There can be one or more pre-defined filters for different languages which have different frequency responses. The frequency responses of the filters are such that when the filters are applied or the signal goes through the filter, the frequencies outside the frequency range of human voice of a specific language have been essentially filtered out, e.g. frequencies outside the marked ranges of different languages of Figure 1 have been essentially filtered out.
In the solution according to the invention signals coming from an input audio source can be processed for both ears separately. The audio signals are separated from each other, they can be amplified and this amplification can be separately adjustable in the signals going to both ears or it can be commonly adjustable. The solution according to the invention can also have the possibility of processing a frequency response for both ears separately. In addition to a possible processing stage for the frequency response is a possibility to adjust the delay of the audio signal. This adjustment is to both channels separately. The final stage can be an amplification stage, but a final amplification stage is optional in the solution of the invention. The method of the invention can be implemented by an apparatus or software or with a combination of apparatus and software.
Fig. 3 presents one solution according to one embodiment of the invention. The apparatus according to the invention receives a signal via the input 120 for an incoming sound signal. Sound source, e.g. one or more microphones, can be connected to the input 120 for an incoming sound signal. The channels, 111, 112, which are intended for both ears, are separated from each other. The channels can be separated from each other e.g. with separating stages 101, 102 of the channels. The frequency response of the signals of the channels 111, 112 can be changed with the frequency response adjustment stages 103, 104, each channel having its own stage, and the operation of them is fully independent of each other. The signals in the channels 111, 112 can also be delayed, i.e. a delay can be formed for them, with the delayer elements 105, 106. The delayer elements 105, 106 can be e.g. delay circuits. The delays can, in the solution according to the invention, be adjusted independently and are independent of each other for both channels.
The apparatus can also comprise amplification stages 107, 108, by means of which the signal can be amplified. The amplification can be of the same magnitude for both channels 111, 112 or in another embodiment of the invention of a different magnitude for both channels 111, 112 and independent of each other. The amplification can also be adjustable for the specific channel or in another embodiment the amplification can be adjustable for both channels as the same magnitude and simultaneously. The signal can be reproduced with the optional sound reproduction means
of the apparatus, which comprises two sound reproduction elements 109, 110. The sound reproduction means can for example be an earphone unit or a loudspeaker unit.
In one embodiment of the invention the delay of the first and/or second channel can be adjusted and calibrated by the user. The adjustment can be done for example so that during the adjustment audio track containing human voice is played. Then while the user is listening audio track containing human voice, the delay between the first and second channel can be adjusted within predefined delay limits of the system. The delay can be changed automatically or by the user. When the user has tested different delay settings, he should select a delay with which he can hear the human voice most clearly. With this delay the brain of the user can successfully synchronize the sound heard by both ears. In the above described way the user has now found his personal and individual delay setting. This individual delay setting for the user can be stored and used when operating the apparatus. The adjustment or calibration audio track containing human voice can contain any language because the language of the human voice doesn't have effect on the delay suitable for a user or finding the correct amount of delay. The adjustment or calibration audio track containing human voice can contain e.g. a short clip of human voice such as one sentence or couple of sentences. If the delay is changed automatically, the delay can be adjusted in one embodiment of the invention based on the background noise level. In one embodiment of the invention the delay can be changed based on G-force and/or background noise level. The G-force information can be received, e.g. from a G-force sensor or accelerometer.
