Speech Science
08 Physiological Acoustics- Coarticulation
Question | Answer |
---|---|
Phonetic Context | how we produce any single phoneme during speech is dependent upon: -Where you’re coming from -Where you’re going to next -It depends on the preceding andfollowing phonemes |
Overlapping Movements | -When we produce a word or phrase, we do not pre-plan each phoneme individually. -Rather an entire strings or sequences of phonemes must be pre-planned as a group |
Assimilation | -refers to how a phoneme is changed to another phoneme due to surrounding sounds. (ex: I want you becomes I wantchu) |
Co-Articulation | -Refers to how a phone is produced differently due to surrounding sounds, but still remains the same phoneme. (ex: The /k/ in cat is produced differently than the /k/ in /skat/ or /back/. |
Two Types of Co-Articulation | .Backward Co-Artic .Forward Co-Artic |
Backward Co-Articulation | -Where the characteristics of one phone can be observed in later phones in the string. -i.e., a later sound contains characteristics (is affected by) an earlier sound. -“Left-to-Right Co-Articulation” |
Causes of Backward Co-Articulation | 1.Inertia 2.Time constraints 3.Mechanical constraints |
Forward Co-Articulation | -Where a preceding phone is influenced by the production of a later-occurring phone. -i.e., a phone contains characteristics of a sound to be produced later in the string. -“Right-to-Left Co-Articulation” |
Cause of Forward Co-Articulation | Anticipation |
Co-Articulation is not influenced by syllable or word boundaries. True or false? | true |
How far can the speech production mechanism look ahead? | It will look ahead until it reaches the next contradictory gesture |
