Magnetic resonance imaging (MRI) is well suited for studying the three-dimensional (3-D) shape of the vocal tract and tongue. However, when MRI is used for speech production measurements, it does not measure normal speech, as the subject lies in supine position and often has to sustain the articulation artificially due to very long acquisition times. In this chapter, MRI is used to estimate the...

objectives: the purpose of the present study is to investigate the oral narrative skills of late talkers mostly caused by mental disorders while they try to comprehend a wordless sequential picture story to create and narrate the relevant story. methods: to this end, 15 (10 male and 5 female) participants were who were the students of a specialized school for physically and mentally retarded st...

The primary focus of speech production research is directed towards obtaining improved understanding and quantitative characterization of the articulatory dynamics, acoustics, and cognition of both normal and pathological human speech. Such efforts are, however, frequently challenged by the lack of appropriate physical and physiological data. A great deal of attention is, hence, given to the de...

When trying to understand behavioral systems, the measurement of time as phase offers many advantages over conventional clock time. We illustrate this with some experimental results in speech production, in which stable coordinations are evident using phase measurements. These stable coordinations may be related to the abstract constituents posited by linguists, but they are manifest only in th...
