Abstract:
In this study, speech targets were nonsense sentences spoken by a Chinese female, and speech maskers were nonsense sentences spoken by other one, two, three, or four Chinese females. All stimuli were presented by two spatially separated loudspeakers. Using the precedence effect, manipulation of the delay between the two loudspeakers for the masker determined whether the target and masker were perceived as coming from the same or different locations. The results show that the one-talker masker produced the lowest masking effect on Chinese speech. When the number of masking talkers increased progressively to 2, 3, and 4, even though informational masking progressively decreased, energetic masking progressively increased, leading to an increased total masking effect on targets. A new form of calculation of the speech intelligibility index confirmed an increase of energetic masking as the masking-talker number increased, even when the long-term average signal-to-noise ratio was unchanged. Some differences between Chinese speech masking and English speech masking were revealed by this study. [Work supported by China NSF and Canadian IHR.]
