Which of the following is a pair of phonemes that are often confused with each other because they share an articulatory feature?

Rationale

/p/ and /b/ are a pair of phonemes that are often confused with each other because they share an articulatory feature.

Both /p/ and /b/ are bilabial stops, produced by bringing both lips together. The primary distinction between them lies in their voicing; /p/ is voiceless while /b/ is voiced. This shared place of articulation often leads to confusion, especially for language learners or in rapid speech contexts.

A (/sh/ and /th/) YOUR ANSWER

These phonemes are articulated at different places: /sh/ is a postalveolar fricative, while /th/ is a dental fricative. They do not share the same articulatory feature, which makes them less likely to be confused compared to /p/ and /b/.

B (/j/ and /h/) YOUR ANSWER

The sounds /j/ (a voiced palatal approximant) and /h/ (a voiceless glottal fricative) differ in both their voicing and place of articulation. This distinctiveness means they are not commonly confused with one another, as they lack a shared articulatory feature.

C (/p/ and /b/) CORRECT

As mentioned, /p/ and /b/ are both produced using the lips (bilabial) and function as stops, differing only in voicing. This similarity in articulation often leads to confusion, particularly in environments where voicing may not be clearly distinguished.

D (/s/ and /k/) YOUR ANSWER

These phonemes have different places of articulation as well; /s/ is an alveolar fricative while /k/ is a velar stop. Because they are articulated in different locations within the vocal tract, they do not share an articulatory feature that would lead to confusion.

Conclusion

Phonemes can often be confused when they share similar articulatory features, such as place and manner of articulation. The pair of /p/ and /b/ exemplifies this concept, as both are bilabial stops differentiated only by voicing. Understanding these phonemic relationships is crucial for language acquisition and phonetic training, highlighting the importance of articulatory features in phonology.

Which of the following is a pair of phonemes that are often confused with each other because they share an articulatory feature?

/p/ and /b/ are a pair of phonemes that are often confused with each other because they share an articulatory feature.
