The use of imperative statements and commands for a voice-activated virtual assistant can set an inappropriate example to children and can potentially lead them to imitate such language in normal conversation. However, current voice-activated virtual assistants are not configured to recognize polite language which can lead to unintended responses. This disclosure describes a virtual assistant that can be configured in a polite mode. The disclosed techniques may be utilized to configure a virtual assistant such that it is responsive only to polite queries. Polite mode is enabled by use of voice stress analysis, sentiment analysis module and natural language understanding (NLU) techniques that are utilized to annotate words/phrases from a query and to determine whether the query is polite.
