6.3.8 Voice Activity Detection (VAD)

The TAA3020 supports voice activity detection (VAD) mode. In this mode, the TAA3020 continuously monitors one of the input channels for voice detection. The device consumes low quiescent current from the AVDD supply in this mode. This feature can be enabled by setting VAD_EN (P0_R117_D0) to 1'b1. On detecting voice activity, the TAA3020 can alert the host through an interrupt or auto wake up and start recording based on the I2C programmed configuration. This alert can be configured through the VAD_MODE (P1_R30_D[7:6]) register bits.

This feature is supported on both the analog and digital microphone interfaces. For lowest power VAD, the digital microphone interface is recommended. The input channel for the VAD can be selected by setting the VAD_CH_SEL (P1_R30_D[5:4]) register bits to an appropriate value. See the Using the Voice Activity Detector (VAD) in the TLV320ADC5120 and TLV320ADC6120 application report for further details.
