BOOSTING ESL, SPEAKING AND VOCABULARY SKILLS WITH NLP: PRACTICAL TOOLS FOR THE MODERN CLASSROOM

Summary/Abstract: Every learner encounters difficulties expressing their thoughts clearly, particularly those acquiring English as a second language. This study investigates the effect of Natural Language Processing (NLP) anchoring techniques on specific speaking sub-skills—pronunciation accuracy, fluency, and speaking confidence—crucial for effective communication. 100 ESL learners aged 16–25 participated in a six-week, mixed-method quasi-experimental study comparing two naturally formed groups: a control group (n = 50) using traditional instruction and an experimental group (n = 50) using NLP-supported tools. The experimental group employed Google Speech-to-Text and ELSA Speak for pronunciation drills, Anki with contextual flashcards for vocabulary retention, and ReadLang for interactive reading practice. The control group followed a conventional curriculum with textbook exercises and teacher-led drills—pre- and post-intervention assessments measured vocabulary retention, speaking proficiency, and confidence levels. Results demonstrated that the NLP-supported group achieved a 36% increase in vocabulary retention compared to 7% in the control group and a 39% improvement in speaking proficiency compared to 16%. Additionally, confidence ratings increased by 25% versus 10% in the control group. Qualitative feedback from self-reflection logs and surveys revealed reduced anxiety during speaking tasks, increased learner autonomy, and higher learning engagement. These findings suggest that targeted NLP anchoring techniques can produce measurable gains across multiple domains of speaking performance. The study highlights the value of integrating technology to supplement rather than replace traditional instruction. Future research should investigate the long-term retention of these gains and explore their application across different proficiency levels, educational contexts, and learner demographics.
