"schwa" before a syllabic liquid or nasal also shows that these are separate syllables.
Stress in simple words stressed first syllable indicates a noun, stressed second syllable
indicates a verb (as in pérvert (N) `My neighbour is a pervert'; pervért (V) `Don't pervert the
idea').
Factors that contribute to prominence of stress in syllables are loudness, length, pitch,
quality.
Stress (accent) relative loudness and tenseness of syllable peak, the use of extra respiratory
energy during a syllable.
Pitch (tone) the auditory property of a sound that enables a listener to place it on a scale
going from low to high, without considering the acoustic properties such as the frequency of
sound.
To produce a stressed syllable one may change the pitch, make the syllable louder, make
the syllable longer.
Fixed stress always word-initial (Czech, Hungarian), always word-final (Turkish, French),
penultimate (Polish).
