| Summary: | The rapid evolution of adolescence language, characterized by slang and idiomatic expressions, presents a significant challenge for machine translation systems. Existing research has extensively covered the translation of languages in general; however, there remains a gap in understanding these systems’ ability when faced with adolescent language. This study aims at (i) the evaluation and the comparison of the accuracy of the translations of colloquial language by Bing Translator, DeepL and HelsinkiNLP from English into Spanish and Italian, (ii) the validity and reliability of two different metrics (i.e., BLEU, METEOR) to assess the accuracy and quality of MT tools with informal language, and (iii) the analysis of how specific features of teenage slang influence the ability of online tools to generate precise and comprehensible translations 1000-character excerpts from the Linguistic Innovators Corpus were translated in Spanish and Italian using DeepL, Bing Translator, and HelsinkiNLP and assessed using BLEU and METEOR metrics to verify their quality and reliability. Our findings show that teenage slang poses challenges for all tools, particularly with phrasal verbs and idioms. Our results also reveal that METEOR seems to be more reliable to assess British teenage language into Spanish and Italian.
