U nderstanding human speech production is of great interest from engineering, linguistic, and several other research points of view. While several types of data available to speech understanding studies lead to different avenues for research, in this article we focus on real-time (RT) magnetic resonance imaging (MRI) as an emerging technique for studying speech production. We discuss the detail...

The purpose is to verify trends of scientific production from 2010 2020, considering the best universities United States, China, European Union (EU), and private companies. top 30 in 2020 EU, US companies were selected SCImago institutions ranking (SIR). positions 2015, SIR three sub-indicators analyzed by means non-parametric statistics, taking into consideration effect time group on rankings....

Auditory and somatosensory systems play a key role in speech motor control. In the act of speaking, segmental speech movements are programmed to reach phonemic sensory goals, which in turn are used to estimate actual sensory feedback in order to further control production. The adult's tendency to automatically imitate a number of acoustic-phonetic characteristics in another speaker's speech how...

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...

This paper presents and evaluates two frequency-domain methods for multi-channel sound source separation. The sources are assumed to couple to the microphones with unknown room responses. Independent component analysis (ICA) is applied in the frequency domain to obtain maximally independent amplitude envelopes (AEs) at every frequency. Due to the nature of ICA, the AEs across frequencies need t...
