Fricative
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 lab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Voiceless Dental Sibilant
The 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 six types with significant perceptual differences: *The voiceless alveolar sibilant (the standard symbol in the International Phonetic Alphabet or IPA) has a strong hissing sound, as the ''s'' in English ''sink''. It is one of the most common sounds in the world. *The voiceless denti-alveolar sibilant (an ''ad hoc'' notation using IPA conventions), also called apico-dental, has a weaker lisping sound like English ''th'' in ''thin''. It occurs in Spanish dialects in southern Spain (eastern Andalusia). *The voiceless alveolar retracted sibilant ">Voiceless alveolar fricative#Voiceless alveolar retracted sibilant"> and the subform apico-alveolar , or called grave, has a weak hushing sound reminiscent of fricatives. It is used in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
