About 2-3 years ago I was using a couple of services where you can select a language and find a foreigner to practice and master different languages. I remember how hard it is to find person available at the same timezone and willing to discuss topics you want to discuss. And today I’ve come across a review of Duolingo’s chatbot which can help you to learn desired language. Clear benefits: 24/7 available conversationalist, relevancy - it suggests you to discuss topics which are popular at the moment (USA President election for example), gamification - you can gain XP points for every correct sentence and ask help when you don’t know what to say. Right now it has some restrictions in terms of vocabulary and accepting written responses only, but I’m sure that this is the future and with AI and speech recognition technology evolving it will be a very popular way to learn a new language - talking to a bot which corrects your pronunciation and help you to form written responses.
