What's the difference between consonant and fricative?

Consonant


Definition:

  • (a.) Having agreement; congruous; consistent; according; -- usually followed by with or to.
  • (a.) Having like sounds.
  • (a.) harmonizing together; accordant; as, consonant tones, consonant chords.
  • (a.) Of or pertaining to consonants; made up of, or containing many, consonants.
  • (n.) An articulate sound which in utterance is usually combined and sounded with an open sound called a vowel; a member of the spoken alphabet other than a vowel; also, a letter or character representing such a sound.

Example Sentences:

  • (20) Acoustic information about the place of articulation of a prevocalic nasal consonant is distributed over two distinct signal portions, the nasal murmur and the onset of the following vowel.

Fricative


Definition:

  • (a.) Produced by the friction or rustling of the breath, intonated or unintonated, through a narrow opening between two of the mouth organs; uttered through a close approach, but not with a complete closure, of the organs of articulation, and hence capable of being continued or prolonged; -- said of certain consonantal sounds, as f, v, s, z, etc.
  • (n.) A fricative consonant letter or sound. See Guide to Pronunciation, // 197-206, etc.

Example Sentences:

  • (1) Phoneme identification responses collected in the same experiments, as well as informal observations about the quality of the restored phoneme, suggested that restoration of a fricative phone distinct from the extraneous noise did not occur; rather, the spectrum of the extraneous noise itself influenced phoneme identification.
  • (2) In another experiment, interdependence of two phonetic judgments was found in responses based on the fricative noise and the vocalic formants of a fricative-vowel syllable.
  • (3) As expected, glottal vibration extended over a longer time in the obstruent interval for voiced fricatives than for voiceless fricatives, and there were more extensive transitions of the first formant adjacent to voiced fricatives than for the voiceless cognates.
  • (4) Hearing-impaired persons with reduced voicing perception for final fricatives were studied for improvement in perception via training or enhancement of the vowel duration cue.
  • (5) Another cue for the fricative-affricate distinction is the duration of the fricative noise in SHOP (CHOP).
  • (6) We report experimental results that confirm Kohler's perceptual assumption: In the context of a following word initial stop, fricatives were less confusable than nasals or unreleased stops.
  • (7) When errors were analyzed according to manner of production, affricatives and fricatives were significantly more susceptible to error than all others.
  • (8) Studies on vowel and consonant recognition suggest enhancing all speech features, but particularly frication and place of articulation should help most patients.
  • (9) Suppression of neural responses to the stop did not depend on whether the neuron responded to either the preceding fricative or the following vowel.
  • (10) Nasopharyngoscopy was used as a visual feedback tool in a 10-year-old girl who had a repaired bilateral cleft lip and palate and was unable to establish velopharyngeal closure during production of sibilant-fricative sounds.
  • (11) The results suggest that listeners base their voicing judgments of intervocalic fricatives on an assessment of the time interval in the fricative during which there is no glottal vibration.
  • (12) That is to say, although hearing speakers commonly use a larger laryngeal gesture for fricatives than for stops and also show durational differences of the abduction and the adduction phases between phonetic categories, the hearing-impaired subjects did not make them.
  • (13) The selection of measurements was based on a theoretical analysis that indicated the acoustic and aerodynamic attributes at the boundaries between fricatives and vowels.
  • (14) In studying language change, Ohala and Lorentz (1977) observed that when the labial-velar glide [w] occurs adjacent to fricative noise, the resulting complex of acoustic features is most often perceived and pronounced as a labial, rather than a velar consonant.
  • (15) Immediately following word-learning experiments, subjects were asked to place 16 CVs into five phonemic categories (voiced & unvoiced stops, voiced & unvoiced fricatives, approximants).
