An Interesting Property of LPCs for Sonorant Vs Fricative Discrimination
Linear prediction (LP) technique estimates an optimum all-pole filter of a given order for a frame of speech signal. The coefficients of the all-pole filter, 1/A(z) are referred to as LP coefficients (LPCs). The gain of the inverse of the all-pole filter, A(z) at z = 1, i.e, at frequency = 0, A(1) corresponds to the sum of LPCs, which has the property of being lower (higher) than a threshold fo...
متن کاملDiscrimination between fricative and affricate in Japanese using time and spectral domain variables
Previous studies on Japanese fricatives and affricates revealed that [s] and [ts] are classified by variables in the time domain (Yamakawa et al., 2012), whereas [ts] and [ʨ] as well as [s] and [ʨ] are classified by variables in the spectral domain (Yamakawa & Amano, 2011). To gain an integrated perspective on these findings, this study examined whether [s] [ts], and [ʨ] can be classified by a ...
متن کاملFricative rhotics in Nusu
Among the world’s languages fricatives are the rarest types of rhotics. They are found in a few African and European languages [13] and as allophones in some Romance languages [4, 8, 9, 12, 17]. Data from Nusu demonstrate the presence of rhotic alveolar fricatives in Asia. Even though they have sometimes been transcribed as retroflex sibilants in earlier studies [11, 20], phonotactic patterns s...
متن کاملToward Learning Visual Discrimination Strategies
Humans learn strategies for visual discrimination through interaction with their environment. Discrimination skills are refined as demanded by the task at hand, and are not a priori determined by any particular feature set. Tasks are typically incompletely specified and evolve continually. This work presents a general framework for learning visual discrimination that addresses some of these cha...
متن کاملLearning Search Strategies through Discrimination
SAGE is an adaptive production system model of strategy learning. The system begins a task with weak, overly general operators and uses these to find a solution to some problem by trial and error. The program then attempts to resolve the problem, using its knowledge of the solution path to determine blame when an error occurs. Once the faulty operator has been found, the system employs a proces...
