Silent sound technology allows for communication without using vocal cords by transforming lip movements into computer-generated sound. It was first popularized in 1968 and demonstrated in 2010. The technology uses electromyography to monitor tiny muscle movements, which are converted into electric signals. Image processing is also used. Applications include use by astronauts, in crowded places, and for those who have lost their voice or want confidential calls. However, the technology is difficult to apply to some languages and not yet practical for widespread use as it requires multiple electrodes attached to the face. Engineers claim it works with 99% efficiency.

Recently more & more hearing impaired people started using sign language. There are about 70 million people in the whole World that are not able to speak (dumb). A dumb person makes communication with other people using their motion of the hand or expressions. . Sign language helps the dumb people to make communication like normal people. The sign language translator which has been already developed uses a glove fitted with sensors that can interpret the 16 English letters in American Sign Language (ASL). Accelerometers and flex sensors are used in this system which increases its overall cost. We proposed a solution as a prototype called as “smart glove-for speech impaired people” which will translate sign language into text. It will help dump and deaf people to express their thoughts in more convenient way. As a sign language we have used traditional finger movements with contact switch wrapped around the user’s fingers. An IR transmitter receiver pair, HT12E and HT12D IC and, Arduino (Micro Controller) board helps transmitting data to PC. Moreover, use of contact switches reduces the system’s overall cost.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

3. WHAT IS SILENT SOUND TECHNOLOGY ?
3
•Technology that helps to transmit
information without using vocal cords.
•It transform lip movements into a
computer generated sound.
•Hence person on other end of phone
receives the information in audio.
4. WHY WE NEED SILENT SOUNDTECHNOLOGY???
•For a better way of communication in noisy public
place.
•Gives a better and new way of communication for
those peoples who lost their voice.
4
•Helps peoples for giving any confidential
information over a phone without worrying about
others.
•As the electronic pulses are universal and can be
immediately converted into any other language of
your choice.
5. ORIGINATION:
•The idea of interpreting silent speech with computer
was popularized in the year 1968.
•“SILENT SOUND TECHNOLOGY” was demonstrated
in CEBIT-2010 .
•This technology is being developed by scientists of
Karlsruhe Institute of Technology (KIT), Germany.
5
6. HOW WE SPEAK…..???
•When we generally speak
aloud, air passes through Larynx
and tongue. Words are produced
using articulator muscle in
mouth and jaw region.
•Even by saying words without
producing sounds weak electric
current are sent from brain to
speech muscles.
6
9. HOW IT WORKS…..????
•A needle electrode or a needle
containing two fine wire
electrodes is inserted through
the skin into the muscle tissue.
•Science skeletal muscles
differs in internal structure so
electrode has to be places at
various location to get accurate
signals.
•Thus by this way speech can be communicated
without sound. 9
10. IMAGE PROCESSING:-
10
•The simplest form of digital image processing
converts the digital data tape into a film image
with minimal corrections and calibrations.
•Then large mainframe computers are
employed for sophisticated interactive
manipulation of data.
11. Continued….
11
Analysis of remotely sensed data is done
using various image processing techniques
and methods that includes:
• Analog image processing
• Digital image processing
12. -:APPLICATIONS:-
12
• For astronauts.
• Effective calls in crowded place.
• Can use without vocal cord.
• Useful to Aphasia (speaking disorder ).
• It gives confidentiality.
• Since the electrical signals are universal they can be
translated into any language(currently being German, English
& French).
•In military works.
13. -:RESTRICTIONS:-
13
•Technology is difficult to apply in some language ( Chinese).
•Complicated to identify person and emotions.
•This device presently needs nine leads to be attached to our
face which is quite impractical to make it usable.
14. •Engineers claim that the device is working
with 99 percent efficiency.
•Silent Sound Technology one of the recent
trends in the field of information technology
implements “Talking without Talking”.
•It will be done of the innovating and useful
technology and in future this technology will
be use in day to day life.

-:CONCLUSIONS:-
