In linguistics, a segment is defined as any discrete unit that can be identified, either physically or auditorily, in the stream of speech. Segments are typically grouped into consonants and vowels, with each segment influencing the segments that come before and after it. These segments are called discrete because they are separate and individual, and temporally ordered. Consonants and vowels, collectively known as segmentals, are the building blocks of oral communication. They are central to conveying the meanings of words and are the core of the syllable. In North American English, there are 25 distinct consonant phonemes, while in NAE, there are approximately 15 vowel sounds.

In spoken languages, segments are typically grouped into consonants and vowels
In linguistics, a segment is defined as "any discrete unit that can be identified, either physically or auditorily, in the stream of speech". The term is most commonly used in phonetics and phonology to refer to the smallest elements in a language. In spoken languages, these segments are typically grouped into consonants and vowels. Consonants and vowels are collectively known as segmentals, and they are the fundamental building blocks of oral communication.
While the term 'segment' is most often used to refer to consonants and vowels, it can also be applied to any minimal unit of a linear sequence that is meaningful to the given field of analysis. For example, in prosodic phonology, a segment can refer to a mora or a syllable, while in morphology, it can refer to a morpheme. In sign language analysis, the term 'segment' refers to cheremes, which are the visual movements of the hands, face, eye blinks, and body. These movements occur in a distinct spatial and temporal order and are represented in the SignWriting script with a spatial cluster of graphemes.
In spoken languages, the syllables that make up words are structured around consonants and vowels. The most sonorous part of a syllable is called the nucleus, which is typically a vowel produced with an unobstructed vocal tract. The segments that come before the nucleus are called the onset, and they are usually consonants. If there are any segments after the nucleus, they are called the coda, which are also typically consonants. Together, the nucleus and coda form the rime.
The structure of a syllable can be represented as CVC, with C standing for consonant and V for vowel. However, this structure can vary, and syllables may have more complex arrangements of consonants and vowels. For example, in English, syllables can begin with up to three consonants, as in the word "strength", and they can occasionally end with up to four consonants, as in the word "angsts". Onsets tend to be "greedy", meaning they will take as many consonants as possible within the constraints of the grammar of the language.
In summary, while segments in spoken languages are typically grouped into consonants and vowels, the term 'segment' can have broader applications depending on the field of analysis. Consonants and vowels are fundamental units of oral communication and play a crucial role in the structure of syllables within words.

Consonants are sounds produced with an obstruction in the vocal tract
Consonants are produced by partially or completely obstructing the airflow through the mouth or nose. This obstruction can be caused by the lips, teeth, tongue, or throat. The vocal tract is made narrower at some point than it usually is, and this narrowing is called a constriction. The consonant produced depends on where in the vocal tract the constriction occurs and how narrow it is. For example, in the stop [t], the tongue tip touches the alveolar ridge and cuts off the airflow. In [s], the tongue tip approaches the alveolar ridge but doesn't touch it, allowing airflow to continue but causing it to become turbulent, resulting in a hissing sound.
The place of articulation refers to the parts of the mouth used to produce the sounds, such as the lips, teeth, alveolar ridge, or palate. The manner of articulation refers to how the vocal tract is obstructed. For example, a complete obstruction of airflow is called a stop or plosive, while a partial obstruction is called a fricative.
Consonants can also be classified according to voicing, which refers to whether the vocal folds are vibrating or not. Voiced consonants like [z] and [v] involve vibration of the vocal folds, while voiceless consonants like [s] and [f] do not.
In summary, consonants are sounds produced with an obstruction in the vocal tract, and this obstruction can vary in terms of location, degree, and whether it involves vibration of the vocal folds.

Vowels are the core of the syllable and are produced with a relatively open vocal tract
In linguistics, a segment is defined as any distinct unit that can be identified in the stream of speech, either physically or auditorily. Segments are typically grouped into consonants and vowels, which are collectively known as segmentals. Vowels are the core of the syllable and are produced with a relatively open vocal tract.
Vowels are one of the two principal classes of speech sounds, the other being consonants. They are usually voiced and closely involved in prosodic variation, such as tone, intonation, and stress. The word 'vowel' comes from the Latin word 'vocalis', meaning 'vocal' or 'uttering voice'. Vowels form the nucleus of a syllable, while consonants form the onset and coda. Vowels are stable segments of speech during which the articulators do not move, allowing the resonance frequencies of the vocal tract to remain more stable.
Vowels are produced without any stricture in the vocal tract, in contrast to consonants, which are characterised by constriction or closure at one or more points along the vocal tract. The vocal tract is most open during vowel phonation, which is why vowels carry the greatest energy in the speech signal. Vowels vary in quality, loudness, and quantity (length). They can be classified according to tongue height, tongue backness, lip rounding, and tenseness.
The acoustics of vowels are well understood and can be analysed through acoustic resonances of the vocal tract, which show up as dark bands on a spectrogram. The position of the jaw, lips, and tongue affect the parameters of the resonant cavity, resulting in different formant values. Open vowels have high F1 frequencies, while close vowels have low F1 frequencies.
In English, the word 'vowel' commonly refers to both vowel sounds and the written symbols that represent them, such as 'a', 'e', 'i', 'o', and 'u'. English also distinguishes between tense and lax vowels, which is a distinction that many other languages do not have. Tense vowels are produced with greater tension in the muscles of the vocal tract than lax vowels, as can be observed in the difference between the words 'sheep' and 'ship'.

Marginal segments are found in onomatopoeic words, interjections, loan words, or a limited number of ordinary words
In linguistics, a segment is defined as "any discrete unit that can be identified, either physically or auditorily, in the stream of speech". Segments are typically grouped into consonants and vowels, which are collectively known as segmentals. They are the smallest elements in a language and are central to conveying the meanings of words.
When analyzing the inventory of segmental units in any given language, some segments will be found to be marginal. Marginal segments are those that are only found in onomatopoeic words, interjections, loanwords, or a limited number of ordinary words. Onomatopoeia is a figure of speech in which a word or phrase phonetically imitates the sound it describes, such as "buzz" or "hiss". Interjections are words or phrases that express emotion or sentiment and are often exclamatory, like "wow" or "yikes". Loanwords are words that are borrowed from another language, such as the word "kindergarten" in English, which is borrowed from German.
Marginal segments are not found throughout the entire language but are often the source of new segments in the general inventory of a language. For example, the sound /ʒ/ in English was originally only found in French loanwords. Marginal segments can also be found in a limited number of ordinary words, though they are not specified as frequently as in the other categories.
In summary, marginal segments are a unique aspect of language that contributes to its evolution and character. They are found in specific types of words and expressions and can vary across different languages.

Segmental features can be controlled independently of one another
In linguistics, a segment is defined as "any discrete unit that can be identified, either physically or auditorily, in the stream of speech". Segments are typically grouped into consonants and vowels, but they can also be applied to any minimal unit of a linear sequence that is meaningful to the given field of analysis. For example, a mora or a syllable in prosodic phonology, a morpheme in morphology, or a chereme in sign language analysis.
In spoken languages, segments are generally not completely discrete in speech production or perception. The articulatory, visual, and acoustic cues that encode them often overlap. However, each speech segment is made up of smaller components called features, which can be controlled independently of one another. These features are the parts of the sound that can be independently controlled by the articulators.
For example, the segment [b] is a consonant, meaning it has some obstruction in the vocal tract. It is indicated with a plus sign to show that the consonant feature is present. The next feature, sonorant, is indicated with a minus sign, meaning that [b] is not a sonorant. The feature sonorant has to do with sonority. Stops have very low sonority because the vocal tract is completely closed for stops, so they are coded as [-sonorant].
Another example is the segment [p], which has every feature in common with [b] except for voicing. If we change the feature voice from plus to minus, we get the segment [p]. Similarly, if we change the feature continuant from minus to plus in the feature matrix for [b], we get the segment [v], which has all the same features as [b] except that it can continue for a long time because it is a fricative.
The ability to control segmental features independently is crucial in pronunciation teaching. Accurate pronunciation of the sounds of a language largely determines the degree of clarity with which a person can communicate. However, this does not mean that pronunciation has to be 100% accurate. Native listeners are usually adept at understanding the meaning of words, phrases, and even sentences that contain mispronunciations.
