Of all the signals human auditory cortex has to process, the one with the most compelling relevance to the listener is arguably speech. Parsing and decoding speech—the conspecifi c signal affording the most rapid and most precise transmission of information—must be considered one of the principal challenges of the auditory system. This chapter concentrates on what speech perception entails and ...

The prevailing approach to speech recognition is the statistical technique known as hidden Markov modeling (HMM), which is capable of reasonable performance in general usage (~95%) – but not much more. The major drawback is that it ignores phonetics, which has the potential for going beyond the acoustic variations to provide a more abstract underlying representation. Also, HMM only produces a s...

It has been shown that acoustic-to-articulatory inversion, i.e. estimation of the articulatory configuration from the corresponding acoustic signal, can be greatly improved by adding visual features extracted from the speaker’s face. In order to make the inversion method usable in a realistic application, these features should be possible to obtain from a monocular frontal face video, where the...

The area function of the vocal tract in all of its spatial detail is not directly computable from the speech signal. But is partial, yet phonetically distinctive, information about articulation recoverable from the acoustic signal that arrives at the listener's ear? The answer to this question is important for phonetics, because various theories of speech perception predict different answers. S...

In this article, we review a specific speech processing research area called acoustic-to-articulatory inversion of speech, or simply speech inversion, which has attracted many researchers and scientists during the last 35 years. The underlying problem refers to the mapping from the acoustic space, which is well-defined since it consists of acoustic signals, to the articulatory space. The latter...
