The letters l and r represent liquid consonants, the former is lateral and the latter is rhotic.
The sounds of letters l and r are:
l: language, late, long.
r: right, ring, ruler.
To pronounce liquid consonants the tongue produces a partial closure in the mouth without constricting the flow of air enough to create turbulence or friction.
When pronouncing l, the tip of the tongue rests against the gum, the back of the tongue is slightly raised to the soft palate, the middle part of the tongue is reduced, the whole tongue becomes a spoon.
- l: voiced, vocal cords vibrate during the articulation of the consonant;
When pronouncing r, the tip of the tongue slightly bends upward, approaching the roots of the upper alveoli. The flow of air, passing through the mouth, makes the tip of the tongue vibrate, producing the sound.
- r: voiced, vocal cords vibrate during the articulation of the consonant.
L and r are liquid consonants, pronounced when the tongue closes partially the mouth, though not limitating the flow, so there is enough air to cause friction.
In lateral sounds (l), the the tip of the tongue is pressing against the gum (the roof of the mouth), forming a spoon with the whole tongue.
- l is voiced, so the vocal cords vibrate during the articulation of the consonant;
Rothic sounds (r) keep the tip of the tongue downwards and the middle part of the tongue is raised. The tip vibrates when the flow of air passes through the mouth, and there is the sound produced.
- r is voiced because vocal cords vibrate during the articulation of the consonant.
