Voice Features
 Two Integrated DSP cores; that comprise: power-efficient voice trigger (VT)
subsystem, high-speed audio processor (APR) subsystem.
 Noise Reduction
o Supports Narrowband and wideband voice communications
o Provides Non-stationary and stationary noise reduction for both
transmit and receive sides.
o Provides High voice quality in various handheld phone positions.
 Acoustic Echo Cancellation: Reduces the effects of echo in both single-talk
(half-duplex) and double-talk (full-duplex) use cases.
 Automatic Gain Control: maintains the voice signal at desired level for both
transmit and receive voice.
