Abstract:
In this study, we examined speaker-dependent (acoustic) and speaker-independent (lexical) linguistic influences on perceived foreign accentedness. Accentedness ratings assigned to Chinese-accented English words were analyzed, taking accentedness as a continuum. The speaker-dependent variables were included as acoustic distances, measured in relation to typical native-speaker values. The speaker-independent variable measures were related to the properties of individual words, not influenced by the speech signal. To the best of the authors' knowledge, this represents the first attempt to examine speaker-dependent and speaker-independent variables simultaneously. The model indicated that the perception of accentedness is affected by both acoustic goodness of fit and lexical properties. The results are discussed in terms of matching variability in the input to multidimensional representations.

Echo
Imagine the sound is reflected back to the ears. Assuming that the source is very close to the human, the difference between hearing the two sounds—the emitted sound and the reflected sound—may be more than the minimum time for perceiving distinct sounds. If this is the case,...
Perceiving Loudness, Pitch, and Location
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by...
Perception of Sound Waves
The pitch of a sound depends on the frequency and the pressure amplitude of the source. Two sounds of the same...
Interference: Path Lengths
Two special sources may be considered when they are in phase. This can be easily achieved by feeding the two sources from the same source. An example would be synchronizing the two speakers by feeding them with the same source, such as the sound waves produced by a tuning fork. This setup ensures that the two sources have the same frequency and are...
