Formant Filter
In speech science and phonetics, a formant is the broad spectral maximum that results from an acoustic resonance of the human vocal tract. In acoustics, a formant is usually defined as a broad peak, or local maximum, in the spectrum. For harmonic sounds, with this definition, the formant frequency is sometimes taken as that of the harmonic that is most augmented by a resonance. The difference between these two definitions resides in whether "formants" characterise the production mechanisms of a sound or the produced sound itself. In practice, the frequency of a spectral peak differs slightly from the associated resonance frequency, except when, by luck, harmonics are aligned with the resonance frequency, or when the sound source is mostly non-harmonic, as in whispering and vocal fry. A room can be said to have formants characteristic of that particular room, due to its resonances, i.e., to the way sound reflects from its walls and objects. Room formants of this nature reinforce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spectrogram -iua-
A spectrogram is a visual representation of the spectrum of frequencies of a signal as it varies with time. When applied to an audio signal, spectrograms are sometimes called sonographs, voiceprints, or voicegrams. When the data are represented in a 3D plot they may be called ''waterfall displays''. Spectrograms are used extensively in the fields of music, linguistics, sonar, radar, speech processing, seismology, ornithology, and others. Spectrograms of audio can be used to identify spoken words phonetically, and to analyse the various calls of animals. A spectrogram can be generated by an optical spectrometer, a bank of band-pass filters, by Fourier transform or by a wavelet transform (in which case it is also known as a scaleogram or scalogram). A spectrogram is usually depicted as a heat map, i.e., as an image with the intensity shown by varying the colour or brightness.

Singing
Singing is the art of creating music with the voice. It is the oldest form of musical expression, and the human voice can be considered the first musical instrument. The definition of singing varies across sources. Some sources define singing as the act of creating musical sounds with the voice. Other common definitions include "the utterance of words or sounds in tuneful succession" or "the production of musical tones by means of the human voice". A person whose profession is singing is called a singer or a vocalist (in jazz or popular music). Singers perform music (arias, recitatives, songs, etc.) that can be sung accompaniment, with or a cappella, without accompaniment by musical instruments. Singing is often done in an ensemble (music), ensemble of musicians, such as a choir. Singers may perform as Soloist (music), soloists or accompanied by anything from a single instrument (as in art songs or some Jazz, jazz styles) up to a symphony orchestra or big band. Many styles o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alveolar Consonant
Alveolar consonants (; UK also ) are articulated with the tongue against or close to the superior alveolar ridge, which is called that because it contains the alveoli (the sockets) of the upper teeth. Alveolar consonants may be articulated with the tip of the tongue (the apical consonants), as in English, or with the flat of the tongue just above the tip (the "blade" of the tongue; called laminal consonants), as in French and Spanish. The International Phonetic Alphabet (IPA) does not have separate symbols for the alveolar consonants. Rather, the same symbol is used for all coronal places of articulation that are not palatalized like English palato-alveolar ''sh'', or retroflex. To disambiguate, the ''bridge'' (, ''etc.'') may be used for a dental consonant, or the under-bar (, ''etc.'') may be used for the postalveolars. differs from dental in that the former is a sibilant and the latter is not. differs from postalveolar in being unpalatalized.

Velar Consonant
Velar consonants are consonants articulated with the back part of the tongue (the dorsum) against the soft palate, the back part of the roof of the mouth (also known as the "velum"). Since the velar region of the roof of the mouth is relatively extensive and the movements of the dorsum are not very precise, velars easily undergo assimilation, shifting their articulation back or to the front depending on the quality of adjacent vowels. They often become automatically ''fronted'', that is partly or completely palatal before a following front vowel, and ''retracted'', that is partly or completely uvular before back vowels. Palatalised velars (like English in ''keen'' or ''cube'') are sometimes referred to as palatovelars. Many languages also have labialized velars, such as , in which the articulation is accompanied by rounding of the lips. There are also labial–velar consonants, which are doubly articulated at the velum and at the lips, such as . This distinction disappea ...

Bilabial Consonant
In phonetics, a bilabial consonant is a labial consonant articulated with both lips. Frequency Bilabial consonants are very common across languages. Only around 0.7% of the world's languages lack bilabial consonants altogether, including Tlingit, Chipewyan, Oneida, and Wichita, though all of these have a labial–velar approximant /w/.

Fricative Consonant
A fricative is a consonant produced by forcing air through a narrow channel made by placing two articulators close together. These may be the lower lip against the upper teeth, in the case of ; the back of the tongue against the soft palate in the case of German (the final consonant of '' Bach''); or the side of the tongue against the molars, in the case of Welsh (appearing twice in the name ''Llanelli''). This turbulent airflow is called frication. A particular subset of fricatives are the sibilants. When forming a sibilant, one still is forcing air through a narrow channel, but in addition, the tongue is curled lengthwise to direct the air over the edge of the teeth. English , , , and are examples of sibilants. The usage of two other terms is less standardized: "Spirant" is an older term for fricatives used by some American and European phoneticians and phonologists for non-sibilant fricatives. "Strident" could mean just "sibilant", but some authors include also labiod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plosives
In phonetics, a plosive, also known as an occlusive or simply a stop, is a pulmonic consonant in which the vocal tract is blocked so that all airflow ceases. The occlusion may be made with the tongue tip or blade (, ), tongue body (, ), lips (, ), or glottis (). Plosives contrast with nasals, where the vocal tract is blocked but airflow continues through the nose, as in and , and with fricatives, where partial occlusion impedes but does not block airflow in the vocal tract. Terminology The terms ''stop, occlusive,'' and ''plosive'' are often used interchangeably. Linguists who distinguish them may not agree on the distinction being made. "Stop" refers to the stopping of the airflow, "occlusive" to the articulation which occludes (blocks) the vocal tract, and "plosive" to the plosion (release burst) of the consonant. Some object to the use of "plosive" for inaudibly released stops, which may then instead be called "applosives". The International Phonetic Association and ...

Lip Rounding
Labialization is a secondary articulatory feature of sounds in some languages. Labialized sounds involve the lips while the remainder of the oral cavity produces another sound. The term is normally restricted to consonants. When vowels involve the lips, they are called rounded. The most common labialized consonants are labialized velars. Most other labialized sounds also have simultaneous velarization, and the process may then be more precisely called labio-velarization. The "labialization" of bilabial consonants often refers to protrusion instead of a secondary articulatory feature velarization. ʷdoesn't mean ˠalthough refers to a labial–velar approximant. In phonology, labialization may also refer to a type of assimilation process. Occurrence Labialization is the most widespread secondary articulation in the world's languages. It is phonemically contrastive in Northwest Caucasian (e.g. Adyghe), Athabaskan, and Salishan language families, among others. Th ...

Low Vowel
An open vowel is a vowel sound in which the tongue is positioned approximately as far as possible from the roof of the mouth. Open vowels are sometimes also called low vowels (in U.S. terminology ) in reference to the low position of the tongue. In the context of the phonology of any particular language, a ''low vowel'' can be any vowel that is more open than a mid vowel. That is, open-mid vowels, near-open vowels, and open vowels can all be considered low vowels.

Front Vowel
A front vowel is a class of vowel sounds used in some spoken languages, its defining characteristic being that the highest point of the tongue is positioned approximately as far forward as possible in the mouth without creating a constriction that would otherwise make it a consonant. Front vowels are sometimes also called bright vowels because they are perceived as sounding brighter than the back vowels. Near-front vowels are essentially a type of front vowel; no language is known to contrast front and near-front vowels based on backness alone. Rounded front vowels are typically centralized, that is, near-front in their articulation. This is one reason they are written to the right of unrounded front vowels in the IPA vowel chart. Partial list The front vowels that have dedicated symbols in the International Phonetic Alphabet are: * close front unrounded vowel * close front compressed vowel * near-close front unrounded vowel * near-close front compressed vowel * clos ...

Pitch (music)
Pitch is a perception, perceptual property that allows sounds to be ordered on a frequency-related scale (music), scale, or more commonly, pitch is the quality that makes it possible to judge sounds as "higher" and "lower" in the sense associated with musical melody, melodies. Pitch is a major auditory system, auditory attribute of musical tones, along with duration (music), duration, loudness, and timbre. Pitch may be quantified as a frequency, but pitch is not a purely objective physical property; it is a subjective Psychoacoustics, psychoacoustical attribute of sound. Historically, the study of pitch and pitch perception has been a central problem in psychoacoustics, and has been instrumental in forming and testing theories of sound representation, processing, and perception in the auditory system. Perception Pitch and frequency Pitch is an auditory sensation in which a listener assigns musical tones to relative positions on a musical scale based primarily on their percep ...
