Syllable
Syllable

When talking about stress, we refer to the degree of force and
loudness with which a syllable is uttered.

A syllable is a pronunciation unit usually larger than a single
sound but smaller than a word --- in most cases a syllable
contains more than one sound, and a word consists of more
than one syllable.
O monosyllabic words
O. / .O dissyllabic words
O.. / .O. trisyllabic words

A stressed syllable is perceived longer in duration and higher in
pitch.
Consonant Cluster
辅音连缀

Consonant cluster refers to the cases where two,
three or four or even more consonants follow one
after the other (with no vowels in between).
CCCVCCCC Pattern
C stands for consonant.
 V stands for vowel.
 In English, it is quite likely that we find three consonants
before a vowel or four consonants after a vowel within a
syllable.
 A syllable is a word part and the basic unit of English
rhythm. It is a pronunciation usually larger than a single
sound but smaller than a word.
e.g. see /si:/

seed /si:d/
speed /spi:d/
spread /spred/
sweet /swi:t/
swept /swept/
mixed /mikst/
texts /teksts/
Consonant Sequence
辅音系列

In phrases, one word may end with a consonant (or
more) and the next word may begin with one (or
more), so that longer sequences quite commonly
occurs. This sequence of consonants in between
words is called consonant sequence.
CCCVCCCC + CCCVCCCC

We have at most 7 consonants between two
vowels in the phrase.
e.g. all over the country
fix this axe for us
The text’s stupid.
all over the country
fix this axe for us
The text’s stupid.
Note:

The glide from one (consonant) to another is quite smooth,
with no gap or hesitation or vowel in between.

Individual sounds may not be necessarily pronounced
equally clear and distinctive. There forms a natural flow of
sounds.

Both consonant cluster and consonant sequence concern
only the phonetic symbols, not the transcription of the
speech sounds.
