What's the difference between fricative and nasal?

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.

  • (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).
  • (16) Among the auditory variables examined, the listeners' tone thresholds at 250 Hz showed the highest relation to perception of fricative voicing.
  • (17) Taken together with previous results, these experiments indicate that listeners take the whole fricative noise, as well as the transitions, into account in fricative identification.
  • (18) When enhanced, the vowels of the utterances were lengthened before voiced fricatives and shortened before voiceless fricatives.
  • (19) Analysis included computation of speech intensity contours, fundamental frequency contours, and spectral parameters from sustained productions of vowels and voiceless fricatives.
  • (20) The effects of different distance measures, filter orders, recognition schemes, and vowels and fricatives were comparatively assessed to determine their effectiveness for the task of gender recognition from speech segments.

Nasal


Definition:

  • (a.) Of or pertaining to the nose.
  • (a.) Having a quality imparted by means of the nose; and specifically, made by lowering the soft palate, in some cases with closure of the oral passage, the voice thus issuing (wholly or partially) through the nose, as in the consonants m, n, ng (see Guide to Pronunciation, // 20, 208); characterized by resonance in the nasal passage; as, a nasal vowel; a nasal utterance.
  • (n.) An elementary sound which is uttered through the nose, or through both the nose and the mouth simultaneously.
  • (n.) A medicine that operates through the nose; an errhine.
  • (n.) Part of a helmet projecting to protect the nose; a nose guard.
  • (n.) One of the nasal bones.
  • (n.) A plate, or scale, on the nose of a fish, etc.

Example Sentences:

  • (4) Ten milliliters of the solution inappropriately came into contact with nasal mucous membranes, causing excessive drug absorption.
  • (5) These data suggest that basophilic cell function in the superficial mucous layer in the nose is of greater significance in the development of nasal symptoms in response to nasal allergy than either mucociliary activity or nasal mucosal hypersensitivity to histamine.
  • (6) Virus replication in nasal turbinates was not diminished while infection in the lung was suppressed sufficiently for the infected mice to survive the infection.
  • (7) Diagnosis and identification of the site of the leak is often inaccurate, even with meticulous care given to placing and removing the nasal pledgets.
  • (8) In this study we investigated the recovery or regenerative process of nasal mucosa in rabbits after mechanical injury on the basis of ultrastructural as well as functional observations.
