INTRODUCTION
One of the key tools in communication is language.Everyone has the ability to communicate with others through language.They are free to share anything is on their thoughts, including ideas, beliefs, and opinions.There are many languages spoken worldwide in addition to national languages.English, a global language, is one of them.Knowing that there are four skills in English-listening, speaking, reading, and writing-the researcher has chosen to concentrate on speaking ability in this study.
The most extensively spoken and utilized language in the world is English.Everybody now has English as one of their top needs.Even in minor instances, it may always be found in daily life.English is used in schools as a topic as well as for communication.The goal of learning English is to improve language proficiency.Students can acquire language skills and practice communicating with people from other nations.
YouTube videos are one of the media that may be used in the teaching and learning process, particularly when it comes to speaking.Therefore, using YouTube videos, the researcher must concentrate on speaking elements such as vocabulary, grammar, pronunciation, and fluency.One of the many media that can be used is a YouTube video.
Learning resources, according to Dale (1969), are all items that can be used to benefit someone in the teaching and learning process.You can utilize YouTube videos as educational resources.According to Jalaluddin (2006), YouTube is a website that provides a variety of video content, including short original videos, video blogs, music videos, movie trailers, and instructive videos.When a YouTube video is labeled as an instructional video, it signifies that the film's subject is readily available English content.One of the abilities that is crucial for learning English is speaking.Almost all teaching and learning processes require participants to ask and answer questions, lead discussions, give presentations, etc.

LITERATURE REVIEW
Good and engaging media are necessary for language instruction.The classroom will be under the teacher's control since the usage of media in the teaching and learning activity will keep the learner's attention on the instructor.Seth (2009) defines instructional media as tools and resources that a teacher can utilize to help students understand a concept, spark their interest, and expand their imaginations during teaching and learning.There are various forms of media that can be utilized during the teaching and learning process.mainly YouTube videos and films.
Google owns YouTube, a website where videos can be shared for free.The name "YouTube" is believed to come from the words "You" (because the video came from the user) and "Tube" (referring to a cathode ray tube television).Videos can be recordings of images or moving pictures.The use of educational technologies and self-created videos on YouTube has made teaching more engaging.Students can access these videos at any time and from anywhere convenient for them.Additionally, YouTube is used to teach theoretical content, involve students, and inspire creative teaching methods (Agazio & Buckley, 2009).
The appeal of using videos in education stems from the amalgamation of visuals and audio.Consequently, it creates a powerful tool that educators can employ to elucidate ideas and also impart knowledge to students through content that stimulates 16 different senses.Undoubtedly, this would aid teachers in simplifying the explanation of intricate notions and procedures by utilizing the visualization that videos offer.
In the field of education, there are several video clips available for users that are informative and educational.Users can access videos ranging from preparing juices to language learning (Kindarto, 2008:82).YouTube is an effective tool that can aid in the acquisition of English language skills, both inside and outside the classroom (Jalaluddin, 2016:1).According to Jalaluddin's research, YouTube has a positive impact on learners' speaking, listening, pronunciation, and vocabulary development.On this platform, learners can learn the correct pronunciation of words directly from native speakers.There are numerous native speakers with excellent pronunciation skills that can be found on YouTube.YouTube is not limited to classroom use, but can also be utilized outside the classroom.
Oral communication refers to the act of expressing one's thoughts, ideas, opinions, suggestions, and even criticisms using the voice.However, speaking is more than just producing sounds.While birds, animals, and babies also make sounds to communicate, they do not engage in speaking.Without the ability to speak, individuals would be unable to interact with others and would be isolated from society.As highlighted by Indramawan (2013), oral communication is a subject that students learn in school.It presents a challenge for students to communicate effectively through speech.Therefore, the strategies, methods, or techniques employed can significantly impact a student's speaking skills.Speaking is an essential component of daily life as it allows people to interact with others.

Research Design
The investigator employed a quantitative research approach.Aliaga and Gunderson (2002) defined this method as the collection of numerical data, followed by mathematical analysis using statistical methods to explain the outcomes.Statistical interpretation is possible with quantitative data.The researcher utilized a Pre-experimental research design.
This scientific approach involves the manipulation and control of one or more independent variables to observe any concomitant variations.Cook and Campbell state that all experimental research involves at least one treatment, an outcome measure, units of assignment, and a comparison to infer changes, which can be attributed to the treatment.
The research design adopted a one-group pre-test-post-test design (Gay, 2014).The group underwent a pre-test (O1), received treatment (X), and completed a post-test (O2).The comparison of pre-test and post-test scores determined the efficacy of the treatment.
