Voiceless alveolar fricatives are a type of fricative consonant pronounced with the tip or blade of the tongue against the alveolar ridge (gum line) just behind the teeth. This refers to a class of sounds, not a single sound. There are at least five types with significant perceptual differences:

The first three types are sibilants, meaning that they are made by directing a stream of air with the tongue towards the teeth and have a piercing, perceptually prominent sound.

Voiceless alveolar sibilant

[edit]

A voiceless alveolar sibilant is a common consonant sound in spoken languages. It is the sound in English words such as sea and pass, and is represented in the International Phonetic Alphabet with s. It has a characteristic high-pitched, highly perceptible hissing sound. For this reason, it is often used to get someone's attention, using a call often written as sssst! or psssst!.

Voiceless alveolar sibilants [s] are one of the most common sounds cross-linguistically. If a language has fricatives, it will most likely have [s].[3] However, some languages have a related sibilant sound, such as [ʃ], but no [s]. In addition, sibilants are absent from most Australian Aboriginal languages, in which fricatives are rare; however, [s] does occur in Kalaw Lagaw Ya.[4]

Features

[edit]

Features of a voiceless alveolar sibilant:

  • Its manner of articulation is sibilant (a subclass of fricatives and affricates), which means it is generally produced with a higher-frequency turbulence. Sibilants may be articulated with various tongue shapes and degrees of palatalization, depending on their place of articulation.
  • There are at least three specific variants of [s]:
    • Dentalized laminal alveolar (commonly called "dental"), which means it is articulated with the tongue blade very close to the upper front teeth, with the tongue tip resting behind lower front teeth. The hissing effect in this variety of [s] is very strong.[5]
    • Non-retracted alveolar, which means it is articulated with either the tip or the blade of the tongue at the alveolar ridge, termed respectively apical and laminal. According to Ladefoged & Maddieson (1996) about half of English speakers use a non-retracted apical articulation.
    • Retracted alveolar, which means it is articulated with either the tip or the blade of the tongue slightly behind the alveolar ridge, termed respectively apical and laminal. Acoustically, it is close to laminal [ʂ] or (to a lesser extent) [ʃ].
  • Its phonation is voiceless, which means it is produced without vibrations of the vocal cords. In some languages the vocal cords are actively separated, so it is always voiceless; in others the cords are lax, so that it may take on the voicing of adjacent sounds.
  • It is an oral consonant, which means that air is not allowed to escape through the nose.
  • It is a median consonant, which means it is produced by directing the airstream down the midline of the tongue, rather than to the sides.
  • Its airstream mechanism is pulmonic, which means it is articulated by pushing air only with the intercostal muscles and abdominal muscles, as in most speech sounds.

Voiceless alveolar non-sibilant fricative

[edit]
Voiceless alveolar non-sibilant fricative
θ̠

A voiceless alveolar non-sibilant fricative (also known as a slit fricative) is a consonantal sound in some spoken languages. As the International Phonetic Alphabet does not have separate symbols for non-sibilant alveolar fricatives, this sound can be transcribed by use of diacritics, such as θ̠ (a retracted [θ]) or (a lowered [t], appears in the IPA Handbook).[85] Additional symbols include θ͇ (with the alveolar diacritic, in extIPA) and ɹ̝̊[86][a] (a raised and devoiced [ɹ], typically part of the affricate [tɹ̝̊]).

Features

[edit]
  • Its manner of articulation is fricative, which means it is produced by constricting air flow through a narrow channel at the place of articulation, causing turbulence. However, it does not have the grooved tongue and directed airflow, or the high frequencies, of a sibilant.
  • Its place of articulation is alveolar, which means it is articulated with either the tip or the blade of the tongue at the alveolar ridge, termed respectively apical and laminal.
  • Its phonation is voiceless, which means it is produced without vibrations of the vocal cords. In some languages the vocal cords are actively separated, so it is always voiceless; in others the cords are lax, so that it may take on the voicing of adjacent sounds.
  • It is an oral consonant, which means that air is not allowed to escape through the nose.
  • It is a median consonant, which means it is produced by directing the airstream down the midline of the tongue, rather than to the sides.
  • Its airstream mechanism is pulmonic, which means it is articulated by pushing air only with the intercostal muscles and abdominal muscles, as in most speech sounds.

Voiceless alveolar tapped fricative

[edit]
Voiceless alveolar tapped fricative
ɾ̞̊

A few languages also have a voiceless alveolar tapped fricative, which is simply a very brief alveolar non-sibilant fricative, with the tongue making the gesture for a tapped stop but not making full contact. This can be indicated in the IPA with the lowering diacritic to show full occlusion did not occur, such as ɾ̞̊.[97] Tapped fricatives are occasionally reported in the literature, though these claims are not generally independently confirmed and so remain dubious.

Flapped fricatives are theoretically possible but are not attested.[97]

Voiceless alveolar spirant approximant

A voiceless alveolar approximant is a similar sound with less turbulent airflow. The IPA has no dedicated symbol that represents this sound, but it may be transcribed as ɹ̥ (a devoiced [ɹ]) or (a lowered [s]). However, there may also be a featural distinction between these two transcriptions: [ɹ̥] has been described as a 'rhotic approximant', while [s̞] has been described as a 'spirant approximant'.[101]
