5.8 Voice Activity Detection (VAD)
5.8.1 Task Description
Due to the increasing sophistication of mobile devices like smartphones, speech-controlled ap-
plications have become incredibly popular. These apps offer a hands-free method for controlling
home devices, facilitating telephony, and allowing drivers to safely use their vehicle’s infotainment
systems while on the go. However, accurately distinguishing between noise and human speech is
critical for these applications to work without interruption. To overcome this issue, Voice Activity
Detection (VAD) systems have been created to recognize speech presence or absence, thus ensuring
consistent and effective operation.
