Aural Discrimination the /iə/ sound and the /ɛð/ sound 

Aural discrimination is the ability to distinguish between different sounds in language, such as differentiating between “fear” and “fare.” In the case of “fear” and “fare,” the sounds that are different are the initial consonants. “Fear” begins with the “f” sound, which is a voiceless labiodental fricative, while “fare” begins with the “f” sound as well, but it is followed by a voiced alveolar approximant “r” sound.

Aural discrimination is an important skill in language learning and communication. It allows individuals to distinguish between different sounds and words, and to understand and produce spoken language accurately. Developing aural discrimination skills can be aided through listening exercises and practice in distinguishing between similar sounds, such as “fear” and “fare.”

 

The phonetic transcriptions for “fear” and “fare” using the International Phonetic Alphabet (IPA):

  • “Fear”: /fɪər/ (transcription includes the vowel shift that occurs in some dialects of English, such as British English)
  • “Fare”: /fɛr/ (transcription includes the unrounded, lax vowel used in the second syllable in most dialects of English)

In IPA, the symbol /f/ represents the “f” sound, the symbol /ɪ/ represents the “ih” sound, the symbol /ə/ represents the “uh” sound, and the symbol /ɛ/ represents the “eh” sound. The symbol /r/ represents the “r” sound, which can be either a voiced alveolar approximant or a voiced alveolar trill, depending on the dialect.

 

The IPA symbols /i/ and /e/ represent different vowel sounds.

The symbol /i/ represents the close front unrounded vowel, which is a high vowel produced with the tongue positioned close to the front of the mouth and the lips unrounded. This vowel sound is found in words like “beat,” “seat,” and “heat” in English.

 

The symbol /e/ represents the close-mid front unrounded vowel, which is a mid-high vowel produced with the tongue positioned close to the front of the mouth and the lips unrounded. This vowel sound is found in words like “bet,” “set,” and “pet” in English.

 

While these two vowel sounds are similar in that they are both front vowels, they differ in terms of their height and degree of openness. /i/ is a high vowel, while /e/ is a mid-high vowel. This means that the tongue is raised higher in the mouth for the sound /i/ compared to /e/. Additionally, /i/ is a closer vowel, meaning that the tongue is positioned closer to the roof of the mouth, while /e/ is a more open vowel.

 

In this focus lesson on aural discrimination, we will be distinguishing between the vowel sounds /iə/ and /ɛð/ in the words “here” and “hair,” “ear” and “air,” “beer” and “bare,” and “deer” and “dare.”

The vowel sound /iə/ is a diphthong, meaning that it is made up of two vowel sounds blended together. The first part of the sound is the close front unrounded vowel /i/, and the second part is the mid-central unrounded vowel /ə/. The /i/ sound is produced with the tongue positioned close to the roof of the mouth, while the /ə/ sound is produced with the tongue in a more central position

 

 

The vowel sound /ɛð/ is a combination of the open-mid front unrounded vowel /ɛ/ and the voiced dental fricative /ð/. The /ɛ/ sound is produced with the tongue positioned in the front of the mouth, while the /ð/ sound is produced with the tongue tip between the upper and lower teeth.

Now, let’s look at the word pairs and how they differ in terms of vowel sounds:

  • “Here” and “hair”: The first word contains the sound /iə/ while the second word contains the sound /ɛð/. The difference between the two is the first sound of each word. The sound /i/ in “here” is more closed and fronted, while the sound /ɛ/ in “hair” is more open and central.
  • “Ear” and “air”: The first word contains the sound /iə/ while the second word contains the sound /ɛð/. Again, the difference between the two is in the first sound of each word. The sound /i/ in “ear” is more closed and fronted, while the sound /ɛ/ in “air” is more open and central.
  • “Beer” and “bare” and “hair”: The first word contains the sound /iə/ while the second word contains the sound /ɛð/. However, the third word, “hair,” contains the sound /ɛə/, which is a similar but distinct vowel sound from /iə/. The difference between /iə/ and /ɛə/ is that the first sound in /iə/ is higher and more fronted than the first sound in /ɛə/.
  • “Deer” and “dare”: The first word contains the sound /iə/ while the second word contains the sound /ɛð/. The difference between the two is again in the first sound of each word. The sound /i/ in “deer” is more closed and fronted, while the sound /ɛ/ in “dare” is more open and central.

To improve aural discrimination between these vowel sounds, it can be helpful to practice saying the words aloud and paying close attention to the differences in sound. Listening to and repeating examples of each sound can also be helpful, as well as engaging in listening exercises where the sounds are presented in a random order to help train the ear to differentiate between them.
