The present work assessed the effects of flattening the fundamental frequency (F0) 29 contour and processing by single-channel noise suppression on the intelligibility of low-pass 30 (LP)-filtered (LPF) sentences. The original F0 contour was replaced by an average flat F0 contour 31 or treated by single-channel noise suppression, followed by application of LP filtering to Mandarin 32 sentences. Processed stimuli were presented to normal-hearing listeners to recognize. Flattening the 33 F0
