Consequently, consonants attenuate or eliminate formants at or near these frequencies, so that they appear weakened or are missing altogether when looking at spectrograms. An antiresonance is the opposite of a resonance, such that the impedance is relatively high rather than low. For consonants, there are also antiresonances in the vocal tract at one or more frequencies due to oral constrictions. With consonants, there is a constriction or closure at some point along the vocal tract. This isn't the case with consonants and nasal sounds, however.
The resonators, then, cause only resonance, reinforcing certain frequency ranges. The air stream, once out of the glottis, passes through the speech organs and is not cut off or constricted by the supra-glottal resonators, nor by the articulators themselves, which means that they are 'open' sounds. (Oral) vowels are formed with no major obstacles in the vocal tract so that there is no build-up of air pressure at any point above the glottis (the supra-glottal spaces). Optimal consonants, on the other hand, are voiceless and lax. In both singing and speech, optimal vowel phonemes are voiced, and are tense and therefore particularly distinct. (Most languages, in fact, have only voiced vowels.) In whispered speech, vowels are devoiced. (Voicing is the difference between the pairs of sounds that are associated with the English letters 's' and 'z', with the 'z' sound being voiced.) In all languages, without exception, most vowels are voiced sounds. At the articulatory level, a voiceless sound is one in which the folds do not vibrate in order to produce the sound. A voiced sound is one in which the vocal folds, which are cartilages inside the larynx, vibrate during the articulation of the vowel. Voice or voicing is a term used in phonetics and phonology to characterize speech sounds, with sounds described as either voiced or voiceless ( or unvoiced). The simplest phonation is called voicing. The different ways in which the vibrations and tension in the larynx affect the quality of a vowel are called phonation. A singer needs to learn to sing vowels while not allowing consonants, which resonate and 'project' more poorly than vowels do, to get in the way. Because of these characteristics, vowels are probably the easiest speech category to recognize in a spectrogram - an electronic device that mesures peaks in the harmonic spectrum of the voice during singing. Vowels are also stable segments of speech during which the articulators do not move, allowing the resonance frequencies of the vocal tract to remain more stable (minus the characteristic waxing and waning of the frequencies due to the rapid and periodic opening and closing of the vocal folds during phonation). They almost always carry the greatest energy in the speech signal because, during vowel phonation, the vocal tract is most open. Vowels are extremely important to singing. Vowels are understood to be syllabic, meaning that they usually form the peak or nucleus (the central part) of a syllable - whereas consonants form the onset (any consonant or sequence of consonants preceding the nucleus) and coda (any consonant or sequence of consonants following the nucleus). In phonetics, a vowel (from the Latin word 'vocalis', meaning 'uttering voice' or 'speaking') is a sound in spoken language that is characterized by an open configuration of the vocal tract, in contrast to consonants, which are characterized by a constriction or closure at one or more points along the vocal tract.
