It has, however, left /n/ (LUNA > /lunə/ 'moon') and /r/ (PIRA > /parə/ 'pear') unchanged. LUNA > /lua/ 'moon', DONARE > /doar/ 'donate', COLORE > /kor/ 'color'), but /r/ remains (CERA > /sera/ 'wax'), but Romanian has transformed the intervocalic non- geminate /l/ into /r/ (SOLEM > /so̯are/ 'sun') and reduced the geminate /ll/ to /l/ (OLLA > /o̯alə/ 'pot'). In Portuguese, intervocalic /n/ and /l/ are typically lost historically (e.g. In North American English, for example, the set /p t k/ has /t/ being by far the most subject to weakening when before an unstressed vowel (the usual American pronunciation has /t/ as a flap in later but normally no weakening of /p/ in caper or of /k/ in faker). More finely-nuanced hierarchies often exist within classes whose members cannot be said to be distinguished by relative sonority. For plosive, the pressure generated from the lungs and diaphragm changes significantly, and the difference in pressure in one's body and outside the mouth is maximal before release (no air is flowing, and the vocal folds are not resisting the air flow). For vowels, there is a consistent level pressure generated from the lungs and diaphragm, and the difference in pressure in one's body and outside the mouth is minimal. That can be demonstrated by putting a few fingers on one's throat and pronouncing an open vowel such as the vowel, and then pronouncing one of the plosives (also known as stop consonants) of the class. The top of the scale, open vowels, has the most air used for vibrations, and the bottom of the scale has the least air being used for vibrations. Vowels have the most vibrations, but consonants are characterized as such in part by the lack of vibrations or a break in vibrations. In simpler terms, the scale has members of the same group hold the same sonority from the greatest to the smallest presence of vibrations in the vocal folds. In English, the sonority scale, from highest to lowest, is the following:

i u j w/ (first two are close vowels, last two are semivowels) High vowels ( close vowels) / glides ( semivowels) Least sonorous (strongest consonantality) Sonority scale Most sonorous (weakest consonantality) to In this way, any contiguous set of sound types may be grouped together on the basis of no more than two features (for instance, glides, liquids, and nasals are ). All sound categories falling under are sonorants, whereas those falling under are obstruents. For instance, as shown in the sonority hierarchy above, vowels are considered, whereas all consonants (including stops, affricates, fricatives, etc.) are considered. The labels on the left refer to distinctive features, and categories of sounds can be grouped together according to whether they share a feature. Sound types are the most sonorous on the left side of the scale, and become progressively less sonorous towards the right (e.g., fricatives are less sonorous than nasals). Sonority hierarchies vary somewhat in which sounds are grouped together.

5 Mechanisms underlying differences in sonority.

Some languages also have assimilation rules based on sonority hierarchy, for example, the Finnish potential mood, in which a less sonorous segment changes to copy a more sonorous adjacent segment (e.g. Sonority hierarchies are especially important when analyzing syllable structure rules about what segments may appear in onsets or codas together, such as SSP, are formulated in terms of the difference of their sonority values. Thus, sounds that are described as more sonorous are less subject to masking by ambient noises. This relates to the degree to which production of phones results in vibrations of air particles. Instead, many researchers refer to sonority as the resonance of speech sounds. However, grounding sonority in amplitude is not universally accepted. For example, pronouncing the vowel will produce a louder sound than the stop, so would rank higher in the hierarchy.

Sonority is loosely defined as the loudness of speech sounds relative to other sounds of the same pitch, length and stress, therefore sonority is often related to rankings for phones to their amplitude. For the distinction between, / / and ⟨ ⟩, see IPA § Brackets and transcription delimiters.Ī sonority hierarchy or sonority scale is a hierarchical ranking of speech sounds (or phones).
