Computers and Speech Recognition: Techniques and Applications

Computers and Speech Recognition: Techniques and Applications Abstract Speech is the most natural and common way of communication between people. It would seem only natural that computer development would eventually progress to the point where people would want to extend the human-computer interface to include speech. Once this happened, numerous techniques were explored. The goals of speech recognition became more and more ambitious, and researchers today continue to push the limits of what computers can do with the spoken word. This paper examines the problem of computer speech recognition by looking at the steps involved in getting from a spoken word to the word's recognition by the machine. The difficulties of continuous speech recognition will be enumerated and examined, as will the most popular recognition technique used today. The analysis ends with a brief description of some of the applications of speech recognition. Introduction Simply put, speech recognition is difficult. A computer does not have a useful thing called an ear that enables it to hear sounds, or a brain to process those sounds into recognizable words and phrases. There are three main stages involved in speech recognition: preprocessing, recognition, and communication. Preprocessing involves taking the speech input and converting it into something the computer can use. During the recognition stage, the computer must identify what has been said. Finally, in the communication stage, the computer acts upon the translated input (Markowitz). There are many inherent difficulties involved in speech recognition. For example, human speech can span more than 20,000 frequencies. A computer would quickly become overwhelmed by data if it was supplied with eve... ...e applications where they could be useful. For many people in the past few years, speech recognition has moved from just being a novelty to becoming an important tool used in their everyday lives. References Books 1. Markowitz, Judith A.

Arizona Senate Bill 1070

Arizona Senate Bill 1070 Our country, today, currently faces many social issues. For instance, drug abuse, child labor, gangs, homelessness, and immigration. The immigration issues is very controversial and continues to rise. Many laws and regulations are being passed to help control this issue. Recently Arizona has passed the Senate Bill 1070 which is causing major problems because it affects human rights. This law should not have been passed because it is increasing racial profiling, rebellion leading to crime, and businesses loosing money. As a person, coming from a Hispanic culture this bill affects me personally. I have family who is in this county with visitation visas or working visas. I even have an uncle with no papers. The bill itself is causing problems in their own state. Arizona is not fixing anything but only making it worst. Yes, the government is trying to get rid of people who technically do not have documentation to be here. The bill pretty much means that a police officer can stop anyone of â€Å"reasonable suspicion† of being illegal. The Arizona Senate Bill 1070 states that if the authority has reasonable suspicion they may stop a person to ask for documentation (arz,gov). It also mentions all people of Hispanic decent will have to carry their legal papers just in case they are stopped. If anyone are caught transporting illegal aliens around they will be in trouble with the law. For example, transporting immigrants could be anything from giving they a ride to the store or to church. People who are housing immigrants will also face consequences. S. B. 1070 is not making the issue any better in Arizona communities, but only making it worst. Many other people argue that most of the crime committed in the United States is caused by immigrants. They feel as if they will not have to be responsible for their actions. People argue that immigrants are causing our economy to fail, and they are the reason why many Americans are unemployed. They may also argue that immigrants have caused our country to become over crowded. First of all, giving permission to stop people on a daily basis because a person is suspicious of someone who does not belong in America is just asking for more racial problems. America is known as a â€Å"melting pot† culture, which is a heterogeneous developed society (world dig). How could someone know if a certain person does not belong in America if we are all from different cultures? In 1939 and 1954 America showed its racisms by removing three million undocumented Mexicans. It was called the â€Å"operation wetback†(academic). It is okay to try and get rid of an issue we are having but no one should be called a term that discriminates their race. Its crazy how history repeats itself and now we have a state trying to start a movement by basically encouraging legal racial profiling. I understand punishing people who do not have legal documentation or green card, but why punish the people who travel with them to even go to the store, church, etc.? The bible mentions, â€Å"love your neighbor† but Arizona makes it hard to love your neighbor because a person is not going to love his Hispanic neighbor. They will not want to risk getting in trouble with the law. Many other little problems continue to rise due to the SB 1070. Also, people are going to rebel against this bill because they do not agree with it. More than half of the crime is not reported, but by placing this law, unreported crimes will surely increase. If an illegal alien gets attacked or even something worst happen they will not report it because they fear they may get deported. That itself will give criminals the feeling to aim any attacks against Hispanics because they have a less chance of getting caught. Finally, the idea of trying to get rid of all the Hispanics rapidly is not a great idea for the economy. Factories are mainly worked by Hispanics or lower poverty. Maybe it is true that Hispanics are take a lot of the jobs and leaving Americans unemployed. But, it is a fact that immigrants are working the jobs many Americans do not want to apply for. Immigrants work for less money and are not picky about having benefits. Deporting immigrants all at once will lead factories to close because its not giving them time to rehire anyone to replace the majority of Hispanics controlling the factories. It will be a domino affect of businesses loosing money.

Performance Analysis The International Basketball...

CHAPTER 2 LITERATURE REVIEW 2.0 Previous research The majority of previous research pertaining to performance analysis in basketball has been focused on the quantitative analysis of game-related statistics, commonly found in a basketball box-score (Sampaio et al., 2006). These game-related statistics include: field goal attempts, field goals made, field goal percentage, 3-point field goal attempts, 3-point field goals made, 3-point field goal percentage, free throws attempted, free throws made, free throw percentage, defensive rebounds, offensive rebounds, assists, steals, blocks, turnovers and personal fouls. The practical value of performance analysis is that well-chosen performance indicators allow good and bad techniques or team performances to be highlighted (Hughes Franks, 2008). Trinic et al. (2002) analysed the International Basketball Federation (FIBA) official performance indicators with the goal of identifying parameters that differentiated between winning and losing teams which played in the final tournaments of the European club championships from 1992 to 2000. Discriminant function structure coefficients (SC) from discriminant analysis exposed that defensive rebounds (SC = 0.42), field goal percentage (3-point field goals made SC = 0.24, 3-point field goals missed SC = -0.30, 2-point field goals made SC = 0.14 and 2-point field goals missed SC = -0.26), and free throw percentage (SC = 0.26) had the highest discriminative power respectively.Show MoreRelatedPreventing PEDs in Professional Sports Essay1198 Words   |  5 PagesThe use of performance enhancing drugs (PEDs) amo ng athletes in professional sports has caused an outrage all around the world for many years.

Changing Times and Marriage Hillary Becker Student Number: 8281930 University College of the North Soc2140: Social Psychology Instructor: Harvey Briggs Thompson Site About eight years ago, I went to a wonderful wedding. It was an expensive wedding; amazing food, incredible decorations, free bar, live entertainment, and the most expensive wedding dress I had ever seen. I bet the cost was well over $35,000.00. I was completely mesmerized and awestruck by the event. Then, oddest thing happened. When I was in the lady’s room doing my lady business, I overheard the bride say laughingly: â€Å"Well, it’s not like its forever†! While I was washing my hands I could hear her voice in my head saying the traditional oath â€Å"till death do†¦show more content†¦How did it go from almost hiding your face due to the shame of being divorced to being like half of the adult population that has been married? I do not profess to be a sociologist; for I am not smart enough to understand the concepts or capable of dressing the part, but I am very interested in how the society I live in is constantly evolving. It may be possible that the decline in permanent marriages are the result of a cultural tendency in perception that promotes individual happiness and fulfillment as the most important goal to achieve. The main reason for marriage today under this concept, is for the individual to acquire love and experience happiness. Society has put greet emphasis on achieving this goal, and that if a person is unhappy, then their life is not fulfilling and they should endeavor to make changes so that their life is fulfilling. Marriage is seen today as something that should not last forever if true happiness is not met. It has become somewhat disposable in concept. If an unhappy marriage was permanent, the door would be closed and that individual would never find self-fulfillment (Shulman, 2004) . This contemporary view of marriage creates an unrealistic myth of the importance of finding a soul mate in order to be happy and once you find this person, things will always be good. If things are not good, then you have made a mistake, an error and you need get a divorce

Commodore Perry’s Journey to Japan Free Essays

After the conclusion of the War of 1812 and prior to the Civil War, the United States Navy entered into a peacetime role. Initially, this role was to protect commerce trading in both inland and international waterways. However, that role was soon expanded upon with Commodore Matthew Calbraith Perry’s journey to Japan. We will write a custom essay sample on Commodore Perry’s Journey to Japan or any similar topic only for you Order Now The journey had its immediate impact, including the signing of a comprehensive treaty that established trade relations with Japan and provided protection for sailors and their ships. Perry’s expedition also had the impact of serving as a precursor for the change in what the Navy’s responsibilities encompassed, which even carry on to the present day Navy. Commodore Perry left for Japan with the objectives of opening up Japanese ports to trade and ensuring American presence and protection in East Asia. These terms were outlined in â€Å"detailed instructions from the Secretary of the Navy John P. Kennedy, diplomatic instructions from the State Department, and a letter from President Millard Fillmore to the Emperor of Japan†2 that Perry carried with him on his voyage. From beginning to end Perry’s voyage spanned nine months and was filled with trials and tribulations. The Japanese were initially turned off to the idea of Americans entering their country, and would not even let them step on land. Only twice did Perry and his squadron come ashore in the nine months prior to the signing of the official treaty. Most of the negotiations took place upon various ships in Perry’s control and the meetings were often difficult to coordinate. Based on notes from Perry’s personal journal, these complications often lead to frustration and Perry was constantly considering employing â€Å"whole force† that he was granted to use if he deemed it necessary to achieve his goals. 3 However, this was ultimately unnecessary, and Perry did well to remind himself that his voyage was diplomatic and pacific in nature. The negotiations were an arduous process and Perry even left Japan returning later with twice as many ships, anticipating a struggle. This was unnecessary as the Japanese agreed to Perry’s desires and the â€Å"black ships† saw no combat. With the agreement of the Japanese the Treaty of Kanagawa was drafted and subsequently signed on 31 March 1854. This treaty allowed for a U. S. consul to be created at Shimoda, and allowed access to the ports of Hakodate and Shimoda for the purpose of obtaining â€Å"wood, water, provisions, and coal, and other articles their necessities may require. † The treaty also required that â€Å"whenever ships of the United States are thrown or wrecked on the coast of Japan, the Japanese vessels will assist them, and carry their crews to Shimoda. Thirdly, men staying in Shimoda and Hakodate, or any seamen shipwrecked shall be free and â€Å"shall not be subject to†¦restrictions and confinement. †4Although there was not a formal agreement on trade in these open ports, Perry assumed correctly that with an American presence in port, trade would come naturally. 5 The initial impact of Perry’s expedition and the treaty with Japan gave the United States Navy many new rol es and an international presence on the high seas. Japan had been a country focused on isolationism for centuries. This isolationism is mainly connected to the zeal of early missionaries who traveled to Japan. The United States was able to avert this conflict in values by Commodore Perry’s outright statement to the Japanese leadership that the United States government â€Å"does not interfere with the religion of its own people, much less with that of other nations. †6 Several attempts were made to open Japan to American trade, but all had failed. One such failure was that of Commodore James Biddle, which proved to be a complete embarrassment for the United States, as he made several mistakes in his conduct and on top of it all needed to be towed out of port by a Japanese ship. The fact that Commodore Perry was successful in his mission changed the status quo in regards to what the United States Navy could and could not do. Perry proved that the United States was capable of having a forward presence in foreign lands and was able to establish international trade in East Asia. The establishment of commercial relations with Japan furthered the Navy’s responsibility in pro tecting trade. Perry’s exploits also showed that diplomacy was a possible way for the United States to establish influence in other countries. Thirdly, Perry and his â€Å"black ships† were the first sign of American deterrence. The fact that American ships were off the coast of Japan ready to attack an underprepared country made it very difficult for the Japanese to negotiate anything in their favor or make any tactical or strategic decisions to remove the threat of Perry’s force. The roles of the Navy that Commodore Perry established in the mid-nineteenth century are still prevalent in the present day. The idea of the Navy as a protector of commerce (although established before Perry, he was instrumental in expanding the Navy’s prevalence in ensuring safe trade) continues into the present day. An example of this would be ships stationed in the Mediterranean Sea. This area, specifically around the Strait of Hormuz is crucial to trade in the Middle East. The presence of the United States Navy maintains a safe trading environment between the United States and its allies, and other countries in the region. Commodore Perry also introduced the idea of deterrence, which is crucial in the operations of the Navy in today’s world. One example of American deterrence is the use of submarines, equipped with nuclear war heads and ballistic missiles, which are virtually invisible to our enemies. Perry also proved that diplomacy was a very potent way to establish influence in foreign countries and maintain a presence without force. This is also seen in the United States establishment of embassies in foreign countries and the use of diplomats to negotiate with foreign countries. Commodore Perry’s expedition to Japan had a tremendous impact on the United States at the time it occurred, but it also had an everlasting impact on how the Navy operates and what roles and responsibilities it chooses to take on.

Down Syndrome 3 Essay Example For Students

Down Syndrome 3 Essay Down Syndrome Down Syndrome is a chromosomal disorder. It occurs in about 1 of every 800 births. People with Down syndrome may have mild to severe learning disabilities. Physical symptoms include a small skull, extra folds of skin under the eyes, and a protruding tongue. People with Down syndrome are subject to a variety of medical problems including heart abnormalities and thyroid gland dysfunction. Survival rates have been increased dramatically in recent years as problems specific to Down syndrome become known, allowing the early treatment. The life expectancy of people with Down syndrome now approaches that of people with out it. Usually its around 55 years old. You would have numerous abnormalities; it wouldnt go over well in school. People dont accustom to that very well in public schools. The genetic cause for Down syndrome is when a person inherits all or part of an extra copy of chromosome 21. Trisomy 21, the inheritance of an entire third copy of this chromosome, accounts for 95 percent of Down syndrome cases. Two other abnormalities each account for 2 to 3 percent of all cases. The first, translocation, takes place when a child inherits an extra piece of chromosome 21 attached to a different chromosome. The second, called mosaic Down syndrome, results when only some cells in the body have the extra chromosome. There is no cure for Down syndrome although prenatal tests are available to identify fetuses with the disorder. Down syndrome can be diagnosed just by looking at the baby at birth. The facial features and characteristics can tell you that. If the attending physician suspects Down syndrome, a karyotype a blood or tissue sample stained to show chromosomes grouped by size, number, and shape will be performed to verify the diagnosis. The most familiar physical traits of Down syndrome include: Low muscle tone Flat facial profile Upward slant to the eyes Abnormal shape and small size of the ears Single deep crease across the center of the palm Excessive ability to extend the joints Fifth finger has one bending joint instead of two Small skin folds on the inner corners of the eyes Excessive space between large and second toe Enlargement of tongue in relationship to size of mouth The majority of these defects can be corrected, resulting in long-term health improvements. Children with Down syndrome also tend to have increased susceptibility to infection, respiratory problems, obstructed digestive tracts, and childhood leukemia. With Down syndrome there is no therapy except some of the defects listed above can be corrected like I stated. But the features of the face remain and cannot be fixed unlike the other ones that can be fixed. There would be no therapy in the future that I can find in my research. Yes, it is possible to detect Down syndrome when the infant is in the uterus. You can do so by screening tests like the Triple Screen and the Alpha-fetoprotein Plus. Both tests measure quantities of various substances in the mothers blood, and together with the womans age, estimate her risk of having a child with Down syndrome. Typically they are offered between 15 and 20 weeks of pregnancy. More accurate are diagnostic tests, which include chorionic villus sampling, amniocentesis, and percutaneous umbilical blood sampling. While these procedures are about 98% to 99% accurate in their detection of Down syndrome there is an increased risk of miscarriage because these tests are performed inside the uterus. Because of this risk, they are recommended primarily for women over the age of 35. For genetic counseling, there is no possible way to stop Down syndrome from happening. Its inherited and it just depends on if the chromosome 21 gets a third chromosome. Someone with Down syndrome could have a child and it could be perfectly normal just depends on the count of chromosome 21.
