Document Summary

There are complex ways to perceive speech: many companies use speech recognition systems to provide services such as booking tickets, auto(cid:373)ated (cid:271)a(cid:374)ki(cid:374)g, a(cid:374)d (cid:272)o(cid:373)puter te(cid:272)h(cid:374)i(cid:272)al support (cid:271)ut the(cid:455) so(cid:373)eti(cid:373)es sa(cid:455) (cid:858)i can(cid:859)t.

Shape of vocal tract is altered by moving the articulators (tongue, lips, teeth, jaw, and soft palate) First formant has lowest frequency; second formant is the next highest. Formants are shown on a sound spectrogram which indicates the pattern of frequencies and intensities over time that make up the acoustic signal. Consonants are produced by a constriction or closing of the vocal tract. The way speech sounds are produced is described by the manner of articulation and the place of articulation: manner articulation: how the articulators (mouth, tongue, teeth, and lips) interact when making a speech sound.
