THE 2020 PERSONALIZED VOICE TRIGGER CHALLENGE BASELINE SYSTEM

Our baseline method consists of a wake-up system and a speaker verification system. As shown in the figure below, we designed a two-pass approach to respond whenever the target speaker says the wake-up word. When the wake-up word detection system triggers, the speaker verification system starts to decide whether the audio segment that triggered the wake-up word detector is indeed spoken by the enrolled target speaker.
