Difference between revisions of "Vowel /eɪ/ phoneme (long vowel)"

Revision as of 00:58, 8 February 2017

The vowel /eɪ/ is a long vowel as in face. It is a diphthong, or double vowel, consisting of the mid-front vowel /e/ plus the short short vowel /ɪ/. Phonologists usually use the International Phonetic Alphabet (IPA) symbols /eɪ/ for this vowel. This is generally contrasted with the short vowel /ɛ/ as in dress in teaching. The pure vowel /e/ by itself is not used in most varieties of English. In this article, slash marks like /ɪ/ indicate a phoneme, while angled brackets like <ɪ> indicate a letter or spelling, and square brackets like [ɪ] indicate a precise phonetic transcription, e.g. indicating a phonetic variant of a sound.

1 Linguistic description

The long vowel /ei/ is not just a longer version of /ɛ/, but is qualitatively different – it is glided or diphthongized.

This vowel is a diphthong, or double vowel consisting of two simple vowels blended together, but /eɪ/ functions as a single long vowel and a single phoneme or unique sound of English. Thus, it is a long vowel because it is a diphthong.
It consists of the vowels /e/ plus /ɪ/, which are pronounced in the front of the mouth. The /e/ vowel is a mid-front vowel, being pronounced with the tongue blade in the middle of the front mouth space, between the /i/ sound as in fleece and the /ɛ/ as in dress. The vowel short vowel /ɪ/ is pronounced with the tongue slightly higher, between /e/ and /i/.
The /e/ component is phonetically the core of the diphthong, while the /ɪ/ is an off-glide. The off-glide component in many standard varieties of English may actually be slightly higher than the /ɪ/ by itself.
The /eɪ/ sound is unrounded, i.e., the lips are not rounded, but since a rounded version of this vowel would be very rare in other languages, this is not a concern for language teachers or language learners.
The /eɪ/ sound can vary in different dialects of English, e.g., within and between North American, British, Australian, and other varieties. For example, in Australian, the first component of the vowel is slightly lowered, so that the vowel is more like /æɪ/.
The symbol /ɪ/ in /eɪ/ is a small capital, lower case /I/. Because of dialectal variation and differences in how some linguists transcribe this sound, the vowel /eɪ/ may also be written as /ei/, /ey/, /ɛɪ/, /ɛi/ or /ɛy/. It should not be written as /e/ or /e:/, as this can give learners the incorrect idea that it is a monophthong like the /e/ or /ɛ/ in their first languages.

1.1 Cross-linguistic comparison

In most languages, the mid-front vowel is a pure /e/, as in most European languages. A few languages have the /eɪ/ diphthong as a regular phoneme, such as Quebec French, Dutch, and Mandarin Chinese (e.g., the syllable mei). It also occurs in Korean, but mainly in English loanwords such as 베이컨 beikŭn "bacon." The monophthong or simple vowel /e/ by itself does not occur in English, except in certain dialects; for example, the /eɪ/ sound in Scottish dialects may be pronounced as /e/, as in the stereotypical Scottish pronunciation of "I'm going to take the train."

1.2 Teaching /eɪ/ production

Students need to learn that this is not just a long version of the /ɛ/ vowel as in dress, nor is it the pure /e/ vowel as in their first language (L1). They can be taught to first say /e/ and then say /i/ (as in we), and then they can blend them into a single sound (this is especially fine, since the /ɪ/ in the /eɪ/ is often slightly higher than /ɪ/ as a simple vowel as in fish). For many learners, teaching will often involve training students to hear and produce the contrast between /eɪ/ as in bait and /ɛ/ as in bet.

Confusingly, dictionaries in Korea use /e/ for the short vowel and /e:/ for the long vowel /eɪ/. This is confusing and incorrect, and lead Koreans to misunderstand their pronunciation. The short vowel should be written /ɛ/, and the long vowel should be written as /eɪ/ or something similar such as /ei/, /ey/, /ɛɪ/, or /eɪ/.

2.4 Practice poem

The following poem is one that I wrote to practice this sound. This deals with exoplanets, or planets outside our solar system, and the possibility of life on such planets.

'The explanets poem'

If you're looking for alien planets in space,
Finding a livable one is quite a chase.
You want a place that life can sustain,
You want a place that can would be humane.
In the air, not too much propane or methane,
Not an atmosphere too painfully insane,
Not where poison falls as rain,
Where from breathing you would have to abstain.
Naturally, in the star's habitable zone is great;
Too near and it'll bake, which is not a good fate;
Too far and the planet's just a lifeless deadweight.
On the surface, you want some good terrain,
And plate tectonics would be a big gain –
Unlike Venus, where the ancient plains
Every half billion years awake from their refrain,
To erupt and melt and destroy that surface once mundane.
Better to have tectonics and a few earthquakes;
Otherwise evolving life there would just bring heartaches.
Besides carbon, a surface with water and silicates and perchlorates
Make things more fun, and you'll need some way to aerate.
So many things necessary for life to awaken,
One little mishap and all hope is shaken.
When can we go to such a place, I just can't wait.
And what would the aliens there think of an earthling primate?

3 More minimal pairs

The following can be used for practice, contrasting /eɪ/ word-initially and medially (middle of word) with /ɛ/. No word-final comparisons are included, because short lax vowels like /ɛ/ generally do not occur word-finally in English. There is perhaps one word with final /ɛ/: the discourse marker meh, which contrasts with may.
