[001] The present invention relates to the field of the deaf assistive device. The invention more particularly relates to a speech to text device for assisting people who have hearing loss or who needs enhanced hearing ability.
BACKGROUND OF THE INVENTION
[002] The following description provides the information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[003] Most of people worldwide suffer from partial or complete hearing loss. Further, in environments with loud ambient noise, it can be very difficult to hear what is being said, particularly if the person speaking is at a greater distance, such as in a conference hall, a large dinner gathering or a sports stadium. A man's speech range is from between 75 Hz and 165 Hz. A woman's speech range is from about 100 Hz to 255 Hz, while a child's voice ranges from 225 Hz to 300 Hz. As a person gets older, they often lose the ability to hear and discern voices in the normal speech range and thus that individual may only be able to catch a few syllables. The hearing impaired person can only catch a few frequencies of the spoken word, though is trying to understand what is being said to them. Often, however, the hearing impaired person may still have hearing in either a higher or lower frequency range. Until now, the normal method to enhance a hearing impaired persons hearing is to increase the volume of the spoken word. If a person has partial hearing loss, the prior method of amplifying the sound only has a limited effect, since the hearing impaired person may not be able to hear the frequency, regardless of the volume. Further the method of amplifying sound is useless for a person who has experienced complete hearing loss. This invention solves the problem of understanding what is spoken to both the person with partial or complete hearing loss.
[004]The hearing impaired person, through the live, real time audio to text function, lip reading to text function, lip reading to audio and frequency changing technology, can effectively read on the built in viewing screen, what is spoken to them and hear what is spoken to them, if they still have hearing in the normal non-voice frequency range. The hearing impaired or the completely deaf person will also be able to enjoy telephone conversations, watch television, movies, the theater or any other venue with the spoken word.
[005] The function of the device is divided into two parts on the basis of frequency of the sound received. It classify the sound into horn and speech. If the identified sound is horn then it vibrate and if the sound is identified as speech, then it send to the cloud through raspberry pi and there the voice recognition algorithm takes special command as input through microphone and convert it into the text form and it send to the display so that the deaf person can read it.
[006] Accordingly, on the basis of aforesaid facts, there remains a need in the prior art to provide changing the frequency of the spoken word, the invention converts audio of the spoken word as well as the lip movement of the speaker, into text that is displayed on the screen.. Therefore, it would be useful and desirable to have a system, method, apparatus and interface to meet the above-mentioned needs.
SUMMARY OF THE PRESENT INVENTION
[007] The present invention provides a speech to text device for assisting people who have hearing loss or who needs enhanced hearing ability. The object of the present invention is to avoid the above-mentioned problems and to classify the sound into horn and speech.
[008] The main aspect of the present invention is to provide a wearable band that converts speech into the text and display it on the device. The system is comprised of, but not limited to a wearable band, a microphone, a raspberry Pi to recognize it as a speech, a display on wearable band, a cloud database and voice recognition algorithm.
[009] If the identified sound is horn then the wearable device vibrates and if the sound is identified as speech, then it send to the cloud through raspberry pi and there the voice recognition algorithm takes special command as input through microphone and convert it into the text form and it send to the display so that the deaf person can read it.

In addition, a number of materials are identified as suitable for various facets of the implementations. These materials are to be treated as exemplary and are not intended to limit the scope of the invention.
[018] Referring now to the drawings, these are illustrated in FIG. 1 and FIG. 2, the present invention provides a speech to text device for assisting people who have hearing loss or who needs enhanced hearing ability. The system is comprised of, but not limited to, a wearable band, a microphone, a raspberry Pi to recognize it as a speech, a display on wearable band, a cloud database and voice recognition algorithm.
[019] In accordance with another embodiment of the present invention, the device consists of 2 special features which includes speech to text conversion and haptic feedback when any sort of noise is heard.

[020] In accordance with another embodiment of the present invention, the identified sound is horn then the wearable device vibrates and if the sound is identified as speech, then it send to the cloud through raspberry pi and there the voice recognition algorithm takes special command as input through microphone and convert it into the text form and it send to the display so that the deaf person can read it.
[021] Identifying the Speech
1. When a person with advance hearing loss, wears this band, he is able to perceive what a person wants to convey to him/her.
1.1-When someone interacts with that person, the microphone recognize the frequency of the incoming sound.
1.2- If the frequency range falls under 100Hz-300Hz, the raspberry Pi then recognize it as a speech.
1.3-Raspberry Pi send that data (speech) to the cloud.
1.4-Cloud translates that data (speech) to text with the help of speech recognition algorithm and send it to raspberry Pi,
1.5-Then raspberry Pi display the text on the screen of the band.

[022] Identifying the Traffic Noise
2. When frequency range falls under 340Hz-420Hz, then that sound is identified as horn or there is traffic behind the user.
2.1-Then that input goes to raspberry Pi and raspberry Pi gives haptic feedback i.e., the device vibrates.
2.2-This alerts the user about the traffic behind the user.
