This piece explores technologies for freer communication "with" machines, i.e. bots (chatbots or conversational agents), rather than the concept of speaking "to" machines, such as Intelligent Assistants (IA) like "Alexa." Bots are computer programmes which simulate natural intelligent communication using text or speech technologies. Recently, interest in chatbots appears to have shifted from whether they can be perceived as human to their ability to imitate natural conversations to achieve specific purposes and provide efficient customer services. This chapter describes the use of modern chatbots for language learning, provides examples of how chatbots could be assessed by language learning students and language teachers in training, and discusses the benefits of communicating with computers for language learners and the limitations of conversational agents.
