Summary of the data collection blocks

Data collection block	Spectral resolution (no. of vocoder channels)	Speaker	Interruption	Vocoder simulation method	No. of trials	No. of sentences
1	4, 8, 16, 32, Full	Male	Silent or with filler noise	CI	5 × 2	130
2	4, 8, 16, 32	Male	Silent or with filler noise	EAS	4 × 2	104
3	4, 8, 16, 32, Full	Female	Silent or with filler noise	CI	5 × 2	130
4	4, 8, 16, 32	Female	Silent or with filler noise	EAS	4 × 2	104

CI refers to the vocoder simulation of cochlear implant processing; EAS refers to the second version of the vocoder simulation that was combined with unprocessed acoustic LPF speech, simulating combined electric–acoustic stimulation
