Voiced dental and alveolar trills
A voiced alveolar trill is a type of consonantal sound used in some spoken languages. An alveolar trill is familiar to many people as the sound of an Italian "r".
The symbol in the International Phonetic Alphabet that represents dental, alveolar, and postalveolar trills is. It is commonly called the rolled R, rolling R, or trilled R. Quite often, is used in phonemic transcriptions of languages like English and German that have rhotic consonants that are not an alveolar trill. That is partly for ease of typesetting and partly because is the letter used in the orthographies of such languages.
In many Indo-European languages, a trill may often be reduced to a single vibration in unstressed positions. In Italian, a simple trill typically displays only one or two vibrations, while a geminate trill will have three or more. Languages where trills always have multiple vibrations include Albanian, Spanish, Cypriot Greek, and a number of Armenian and Portuguese dialects.
People with ankyloglossia may find it exceptionally difficult to articulate the sound because of the limited mobility of their tongues.

Features
Features of a voiced alveolar trill:- Its place of articulation may be:
- * dental,
- * alveolar, or
- * post-alveolar.
- It is most often apical, which means it is pronounced with the tip of the tongue.

Voiced alveolar fricative trill
In Czech, there are two contrasting alveolar trills. Besides the typical apical trill, written r, there is another laminal trill, written ř, in words such as rybáři 'fishermen' and the common surname Dvořák. Its manner of articulation is similar to but is laminal and the body of the tongue is raised. It is thus partially fricative, with the frication sounding rather like but less retracted. It sounds like a simultaneous and, and some speakers tend to pronounce it as,, or. In the IPA, it is typically written as plus the raising diacritic,, but it has also been written as laminal. The Kobon language of Papua New Guinea also has a fricative trill, but the degree of frication is variable. The Kpwe language of Cameroon has been reported to have a similar sound.Features
Features of the voiced alveolar fricative trill:- Its place of articulation is laminal alveolar, which means it is articulated with the blade of the tongue at the alveolar ridge.
