Device-directed Utterance Detection

Understand

In this work, we propose a classifier for distinguishing device-directed queries from background speech in the context of interactions with voice assistants.

• Applications include rejection of false wake-ups or unintended interactions as well as enabling wake-word free follow-up queries.
• Consider the example interaction: $"Computer,~play~music", "Computer,~reduce~the~volume"$.
• In this interaction, the user needs to repeat the wake-word ($Computer$) for the second query.
