The rise of AI in language learning
Artificial Intelligence has transformed language learning by offering personalized and optimized tools.
Through Natural Language Processing (NLP), AI-based platforms assess learners' proficiency levels and tailor lessons accordingly. These systems use chatbots and virtual language tutors to provide real-time feedback, simulate immersive language environments, and engage learners in conversational practice.
Machine learning continuously refines these systems by analyzing data to enhance content and teaching methods.
Ultimately, AI empowers learners with dynamic, motivating and efficient tools, accelerating their path to linguistic proficiency.
Let’s take a closer look at the different technologies used by artificial intelligence for language learning.

Overview of AI technologies relevant to language acquisition
Natural Language Processing (NLP)
Natural Language Processing, or NLP, is a field of artificial intelligence that focuses on enabling computers to understand, interpret, and generate human language.
It involves the development of algorithms and models that allow machines to process and comprehend natural language data, such as text and speech.
NLP techniques enable computers to extract meaning, sentiment, context, and relationships from textual data, facilitating tasks like language translation, sentiment analysis, text summarization, chatbots, and language generation.
NLP plays a key role in various applications, powering advancements in language-related technologies and enabling more effective communication between humans and machines.
However, it’s important to underline the current limits of NLP: it’s still a machine, not a human.
Machine learning algorithms
Machine learning algorithms are computational methods that enable computers to learn patterns, rules, and relationships within data without being explicitly programmed.
These algorithms utilize statistical techniques to identify patterns and make predictions or decisions based on input data. They learn from experience, continuously improving their performance as they are exposed to more data.
The various types of machine learning algorithms include:
Supervised learning: Algorithms learn from labeled data, making predictions or classifications based on input-output pairs.
Unsupervised learning: Algorithms identify patterns or structures within unlabeled data.
Reinforcement learning: Algorithms learn by interacting with an environment, receiving feedback in the form of rewards or penalties based on their actions.
Machine learning algorithms are used in various applications such as image and speech recognition, recommendation systems, fraud detection, autonomous vehicles, and, in our context, natural language processing, among many others.
Chatbots and virtual language tutors
Chatbots
Chatbots are computer programs that simulate human conversation using Natural Language Processing (NLP). In language learning, chatbots engage learners in conversational practice, allowing them to interact in the target language.
These bots can hold dialogues, provide immediate feedback, answer questions, and offer language exercises in a conversational format. They enable learners to practice speaking, listening, and comprehension skills in a natural and interactive manner.
Recently, Berlitz launched a chatbot called “The Learning Assistant”. The Learning Assistant can help students with explanations, examples, translations and grammar questions. Currently, it can respond to questions in 95 languages
Virtual language tutors
Virtual language tutors are advanced AI systems that act as personalized language instructors. They leverage AI and machine learning to assess learners' proficiency levels, identify strengths and weaknesses, and create customized learning paths.
These tutors deliver adaptive lessons, adjusting content difficulty based on individual progress. They often incorporate various learning modalities, including interactive exercises, multimedia content, and simulated real-life scenarios, to provide a comprehensive learning experience and a personalized guidance.
