A digital voice assistant that understands and responds to natural language voice commands. To activate such a voice assistant, the user is required to utter an activation keyword. Such explicit activation requires the user to interrupt the natural flow of conversation, e.g., with others in the household. Many households are multilingual, e.g., where members of the household speak with each other in a particular language, but are capable of speaking other languages. This disclosure enables automatic activation of a digital voice assistant upon detection of a specific spoken language. For example, if the household members speak to each other in Polish, but are also capable of speaking English, the voice assistant can be set up to automatically detect spoken English and determine that a command was issued. The described techniques are applicable in any situation where users converse in a language different from the activation language of the voice assistant.
