초록
The purpose of this study was to estimate a difference of cue weighting strategies to perceive fricative sounds in normal hearing adults (NHA), across various listening conditions. Eighteen NHA participated to four listening conditions (quiet, 0, -5, and -10 dB SNR). Two seven-step continua of synthetic CV syllables were constructed, with frication pole frequency varied from /s/ to /∫/ within the continuum, and appropriate formant transition values varied across continua. Relative weights applied to the frication, transition, and interaction cues were determined. In quiet condition, NHA gave more perceptul weight to the formant transition cue than to the frication, whereas they gave more perceptual weight to the frication in noisy conditions, rather than the formant transition. Also, in noisy conditions, they attended more to the frication cues than in quiet condition, and at -10 dB SNR condition, cue weighting strategy of fricative perception was significantly different to other conditions. The weight given the degree of cue interaction was not different across four conditions. Results from comparison of this study and the previous study in quiet condition showed that Korean listeners gave more attention to transition cues than American listeners. The results suggest that 1) the longer duration cues were more weighted for perception in difficult listening condition than in easy listening condition, compared to the shorter duration cues and 2) Korean listeners and American listeners used the different cue weighting strategy for perception of fricative sounds.
Abstract
The purpose of this study was to estimate a difference of cue weighting strategies to perceive fricative sounds in normal hearing adults (NHA), across various listening conditions. Eighteen NHA participated to four listening conditions (quiet, 0, -5, and -10 dB SNR). Two seven-step continua of synthetic CV syllables were constructed, with frication pole frequency varied from /s/ to /∫/ within the continuum, and appropriate formant transition values varied across continua. Relative weights applied to the frication, transition, and interaction cues were determined. In quiet condition, NHA gave more perceptul weight to the formant transition cue than to the frication, whereas they gave more perceptual weight to the frication in noisy conditions, rather than the formant transition. Also, in noisy conditions, they attended more to the frication cues than in quiet condition, and at -10 dB SNR condition, cue weighting strategy of fricative perception was significantly different to other conditions. The weight given the degree of cue interaction was not different across four conditions. Results from comparison of this study and the previous study in quiet condition showed that Korean listeners gave more attention to transition cues than American listeners. The results suggest that 1) the longer duration cues were more weighted for perception in difficult listening condition than in easy listening condition, compared to the shorter duration cues and 2) Korean listeners and American listeners used the different cue weighting strategy for perception of fricative sounds.
