Application for Students' Pronunciation at SMK  43 students' pronunciation skills through this research finding and discussion.

The result of Normality Testing
In this research, the researcher used the Lilliefors formula to test the normality of the data.The result showed that the L0 (count) > Ltable then the sample comes from a population that is normally distributed.Based on the table above, L0 is the largest value of | F(Zi) -S(Zi) | then gets 0.167, and Ltable is obtained from the Ltable = 0.161 (Haniah, 2013).It means the H0 was accepted and H1 was rejected.Further, the sample of the population that was normally distributed.

The result of Homogeneity Testing
In the next step, the researcher got of Fcount 1.22, and Ftable from df (degree of freedom) of two variables was 4.20 (Bustami, et al., 2014).The result of Ftable can be seen in appendix 30.It means Fcount < Ftable.So, the conclusion is that pre-test in-class control and non-control were homogenous.
After the researcher knew the pre-test in class control was homogenous.Thus, the researcher looking for post-test in class noncontrol.

The result of the Pre-Test Score
The pre-test showed that the mean score of class control was lower than class non-control.The researcher conducted of pre-test in class control and non-control the lowest score of 60 students was 35 with the number of students who get it was 1 person.Moreover, the highest score of 60 students was 1 person who got the highest score of 70 but the highest score was still lower than the KKM which had been determined by SMK Kesehatan of Kapuas Raya Sintang was 75.

The result of the Post-Test Score
Based on the result of the post-test the researcher found that the mean score of the post of class control was higher than class non-control.Therefore, the researcher concludes that the mean score of students taught by using the Elsa Speak application was better than the mean score of students who taught without the Elsa Speak application.the researcher conducted posttest in class control and non-control the lowest score of 60 students was 58 with the number of students who get it is 1 person.Moreover, the highest score of 60 students was 1 person who got the highest score of 82 and the highest score was higher than the KKM which had been determined by SMK Kesehatan of Kapuas Raya Sintang 75.

t-Test
Based on the result of the independent sample test, showed the result of the t-test from the post-test in class control and class non-control.It indicated that there was a significant difference between the mean score from the class control which was 76.46 and class non-control was 63.96.The standard deviation of class control was 13.09 and class non-control was 14.66.
The data of the independent sample test shows that the result of ttable (df = 28) = ttable was 1.701 and t0 = 27.77.Moreover, the researcher concluded that t0 was higher than ttable (27.77 > 1.701).It means the null hypothesis (H0) was rejected and the alternative hypothesis (H1) was accepted.Therefore, it was proved that the using Elsa Speak pplication affects increased students' pronunciation.

The Effect of Size
In order to know the effect size level of the research, the researcher used the calculation by Cohen (Fatah, 2019).In this calculation, the mean and the standard deviations of post-test from control and noncontrol classes are required which have been obtained from group descriptive statistics table.The means score of control class is 76.46 while the non-control class is 63.69.Meanwhile, the standard deviation of control class is 22.92 and the non-control class is 19.69.After obtaining the result it can be seen that the effect of size is 0.58.Based on the basic of Cohen (Fatah, 2019) effect of size criteria was Moderate Effect, it indicates that the students in control class are affected by Elsa Speak application that their pronunciation knowledge is enhanced.

The Analysis of Hypothesis
The research was conducted to answer the research question: "How does the effect of using the Elsa Speak application on students' pronunciation skills?".The statistical hypothesis is explained as follows: a. (H0): There is no improvement in the students' pronunciation.b. (H1): There is an improvement in the students' pronunciation.
In addition, according to Sarwono (2022) the assumption of the statistical hypothesis: a.If t0 > ttable then H0 is rejected and H1 is accepted.b.If t0 < ttable H0 is accepted and H1 is rejected.
Based on the result of t0 (27.77) is higher than the ttable (1.701) in the significant level of ɑ = 0.05 (5%).Therefore, the t0 > ttable means that the alternative hypothesis (H1) was accepted and the null hypothesis (H0) was rejected.Thus, it indicated that the use of the Elsa Speak application is effective to develop students' pronunciation in the eleventh grade of students at SMK Kesehatan of Kapuas Raya Sintang.

Discussion
Based on the previous chapter, the researcher analyses that the Elsa Speak application have the potential to improve students' pronunciation skill.Further, the researcher hypothesized that the Elsa Speak application may also give an effect on the students' pronunciation skills.Moreover, this research is useful for other researchers that study on Elsa Speak application.In brief, at the beginning of the activity, the test was administrated to know the level of validity and reliability of the test instrument.After knowing the validity and reliability of the test instrument, the researcher gave the pronunciation test of class control and non-control.It is to know the correlation among the variables.Pronunciation refers to the production of sound.Furthermore, in the pronunciation test the researcher gave a different test.The instrument of the test was 15 items.10 items form words and 5 items form sentences.The test pronunciation was taken by 30 students in a pre-test and posttest.
In class control that has the mean of the pre-test was 46.03 before doing the treatments by using the Elsa Speak application.Further, the mean of the posttest score was increased to 76.47 after doing treatments.Moreover, the students' mean scores for class control of post-test were highest scores than class control of pre-test.In addition, the result of this research is similar to Gelu (2020), the improvement from the result of the pre-test and post-test to investigate after using the Elsa Speak app for senior high school students by using pre-test and post-test.
By analyzing the result of the data calculation in the previous chapter, where the alternative hypothesis (H1) was accepted, it means that there is a correlation between taught used Elsa Speak application and without it (originally) at SMK Kesehatan of Kapus Raya Sintang in the academic year 2021/2022.In other words, the null hypothesis (H0) was rejected and the alternative hypothesis (H1) was accepted.
Further, the researcher used a quasiexperimental design, an experimental approach to casual research done in field settings (Stouffer, 1950).The research focuses on pronunciation.It is how a word or a language is spoken.In addition, according to Paulston & Burder (1976), it is about how people create sound in a language.The statement of pronunciation alludes to the manner of producing sounds to communicate meanings (Yates, 2002).Therefore, in communication, it is important to say good pronunciation because every word is easy to understand and the researcher used media, which can help the students to learn English (Aboagye et al., 2020), especially pronunciation.Some

Application for Students' Pronunciation at SMK  45 researchers who had found that it is effective to use the kinds of technology in helping students to have good pronunciation.The improvement of technology is easily conducted with the help of teaching technology, including teaching pronunciation.Especially, the Elsa Speak application.Elsa Speak has a mobile app, which allows users to practice and improve pronunciation and intonation skills through a series of server evaluations.So, in addition, according to Taqy (2021), Elsa Speak is an English pronunciation app that helps people speak English confidently and clearly.The most accurate and useful test people can take to discover their English-speaking proficiency level.

CONCLUSION
To conquer the students' misscommunication, the researcher intended to use the Elsa Speak application as a solution to enhance students' misscommunication, especially pronunciation skills.In this case, the researcher used communication activities where the design activities for the students to practice specific sounds when the person listens someone to speak and pays attention to the melody it hears, it is intonation.Based on it, according to Kelly (2000), the term intonation refers to the way the voice goes up and down in pitch when the person speaking.In addition, as well as helping to determine what to mean, intonation gives us clues about the attitude of the speaker.
Moreover, about stress, according to Birjandi (2005) describe the word stress means "loudness".It also stated that stress is a term that we apply to words in isolation that have more than one syllable.In addition, he stated that certain stressed syllables are made with more effort than unstressed ones; the muscle in the lungs seem to expel air more aggressively than for unstressed syllables.Based on the explanation above, it can be concluded that a word with more than one syllable at least has one stressed syllable, and also when there is a stressed syllable, the other syllables need to be unstressed.For one syllable to be perceived as stressed, the syllables around it need to be unstressed (Kelly, 2000).
In this research, students had difficultiy pronounciating the words "foreign", they read it according to the letters.Furthemore, the word "foreign" is included in the labio-dental because the reader pronounces the word using the lower lip and the upper teeth such as / 'fɔ.rǝn/ and this is the correct pronunciation accronding to the Elsa Speak application.taught by using the Elsa Speak application of pronunciation are expected to achieve better pronunciation.
The result of hypothesis testing showed that the use of the Elsa Speak application gave a significant effect of size was 0.58, the criteria was Moderate Effect.It indicates that the students in control class are affected by Elsa Speak application that their pronunciation knowledge is enhanced.
Also, it is proven by the calculation result of the independent sample t-test, the result of t0 was higher than ttable.Moreover, there were significant between students who taught by using the Elsa Speak application and without the Elsa Speak application (original).
After calculating the normality testing, it proved that the significance of the data from class control and non-control in pre-test and post-test were normal.The pretest score showed the data of Lilliefors to find out L0.In class, the control was 0.192 and the class non-control was 0.346.Meanwhile, the post-test scores also showed the data of Lilliefors to find out L0. In-class control was 0.208 and the class non-control was 0.267.It concludes that both of the classes in pre-test and post-test were lower than Ltable = 0161.It means the result was normal.
In another way, the data analysis that used an independent sample t-test proved statistically the effect of using the Elsa Speak application.It can be seen the statistical significance shown by the posttest data analyzed that the results were t (df = 28) = 22.77 and ttable was 1.701.Moreover, the researcher concluded that t0 was higher than ttable (22.77 > 1.701).It means the null hypothesis (H0) was rejected and the alternative hypothesis (H1) was accepted.Therefore, it was proved that the using Elsa Speak application affects increased students' pronunciation.
From the data analysis above, the researcher concludes that the Elsa Speak application can give a significant effect on students' pronunciation.It is because the score on the pronunciation test after the researcher did the treatments was higher than before being taught by the Elsa Speak application.It means that using the Elsa Speak application showed a positive effect to be implemented for students, especially for the eleventh-grade students of SMK Kesehatan of Kapuas Raya Sintang.
