| Abstract: | Speech acoustics varies from speaker to speaker, microphone to microphone, etc. Recently, a novel method was proposed to separate these static non-linguistic features from speech as spectral smoothing can separate pitch information from speech. Absolute properties of speech events, such as formants and spectrums, are completely discarded and only the phonic differences or contrasts between the events are extracted to form their external structure. This structure is called the acoustic universal structure and regarded as physical implementation of structural phonology because the structure is considered to represent only the linguistic and para-linguistic information. In this paper, the size of the structure is focused on and its correlation with the para-linguistic information is examined. Results showed that the size can be interpreted as magnitude of articulatory efforts made in speech production. | ||
