| Question | Answer |
|---|---|
| stops/nasal | mastered earlier, complete obstruction of air stream, complete production, tactile, p & m |
| glides | w & y, developed early since vowels, known as semi-vowels |
| fricatives | h & f exceptions, v-s-z harder |
| manner of production | 4 yrs mid point, 7 years of age move to affricates, r, clusters |
| syl. kids make | cv, release (pie), arrest (up) |
| inconsistencies during development | medial arrests & phonetic context |
| medial arrestor consonants | cvccvc, last in development, cupcake, explains gradual development |
| phonetic context | cup--->ticket; can't adjust from one position to the next, tongue can move up then down, based off motor control level |
| misarticulation errors | omission, substitution, distortions, additions |
| omission | worst error, leave out sounds, napkin-->nakin, some h-w-y common to omit, seen in first word |
| substitution | wrong manner, wrong place, manner & place |
| wrong manner | most advanced error, t/s (error/target) |
| wrong place | best kind of error,can still understand kid, close to right target, least negative |
| manner & place | t/f, move place and manner |
| voicing | rarely wrong, added to releasing consonants, taken away from arrestor consonants, don't see after young age |
| sign error | g/s, velor/alveolar |
| distortions | most advanced, not standard production of sound, close but not target, soup->scheloup, messy, hard to fix,usually can understand |
| addition | keeps target, add additional sound, please->puhlease, easier to produce, not expected in typical development |
| intelligibility | how well listener understands what speaker says, speaker must relate with listener, predictive course, mastered around 4 yrs |
