I have been practicing Spanish with ChatGPT, "BBC Business Technology journalist Christine Rowe excitedly told her Argentine friend." It can correct my mistakes and explain the regional characteristics of Spanish to me. "Rowe's friend was somewhat disappointed and said," So, has artificial intelligence replaced me? "Rowe didn't think so. Of course, artificial intelligence cannot replace friends, but its convenience and knowledge reserve are amazing. More and more people are discovering that ChatGPT is beneficial for language learning. An architect in Costa Rica told the BBC that with the help of artificial intelligence, he was able to quickly find the professional English vocabulary he needed, saving a lot of time. A coffee shop owner in South Africa sighed, "It can provide me with a verb tense table and help me improve my grammar." Quazel is an artificial intelligence language learning application launched by the Federal Institute of Technology in Zurich, Switzerland. Philip Hajimina, the founder and CEO of the company that developed the software, told the UK science website "Science X" that most traditional language learning applications are presented in written form, Even software that provides speech recognition functionality responds to users using preset sentences. This makes the conversation patterned. "Learners can discuss all kinds of things they are interested in with AI, such as food, sports, and even philosophical problems. If learners have words or Syntax error, the application will correct them in time," Hajimina said. We hope to make language learning easier and allow more people to enjoy the benefits of exclusive language mentors. Hajimina is confident in the products developed by his company. This artificial intelligence mentor is proficient in 21 languages and has sufficient patience for learners. "Students can really get some results when they practice their English by using a companion Chatbot such as Replika," said Branka Krimova, associate professor of Applied linguistics at the University of Cralovay in Heradz, Czech Republic, "but there are many problems with such programs, such as repeated conversations and unmodified language. Sometimes such programs require students to provide sexy photos, which is too disrespectful." However, Krimova assessed the feasibility and practicability of Chatbot such as ChatGPT in college English teaching and found that Chatbot can really improve students' vocabulary, enrich their grammar knowledge, cultivate their language ability, and correct errors in time. According to the BBC, technology developers have continuously optimized and developed a series of language based artificial intelligence applications based on "language functionality". Compared with companion Chatbot such as "Replika", they are more suitable for language learners. Federico Ruiz Cassarino is the developer of LangAI, a language learning Chatbot. He developed this application based on his English learning experience. Compared to academic methods, his software places more emphasis on practicality. With the help of this application, his English proficiency has significantly improved. Now, he has embarked on a journey of learning Italian. Casarino told the BBC that many people feel embarrassed because they make mistakes in foreign language conversations, but
