Phonetic boundaries and judgmental central tendency

Blind Location of Phonetic Boundaries

This contribution addresses the location of phonetic boundaries (LPB) for Czech phonetic categories. A novel method based on discriminant function and Bayesian change-point detectors (BCD) is suggested and tested for synthetic and real speech; the consistency and strength of the method was confirmed by experiment. The LPB process for finding significant boundaries consists of four steps: pitch-...

Innate phonetic boundaries revisited (L)

Nittrouer @J. Acoust. Soc. Am. 110, 1598–1605 ~2001!# raised several serious concerns with the so-called Universal Theory of phonetic category development that she characterized as the accepted wisdom in the field of infant speech perception. She then presented data from infants and children that were claimed to be inconsistent with Universal Theory and led her to question the entire notion of ...

Perceived Prosodic Boundaries and their Phonetic Correlates

This paper addresses two main questions: (a) Can listeners assign values of perceived boundary strength to the juncture between any two words? (b) If so, what is the relationship between these values and various (combinations of) suprasegmental features. Three speakers read a set of twenty utterances of varying length and complexity. A panel of nineteen listeners assigned boundary strength valu...

Central tendency and variability in biological systems

In this article, the author reviews the manner in which researchers characterize data. Normality, standard deviation, mean, and other concepts related to parametric statistics are discussed in common language, with a minimum of jargon and with clinical examples.
