當陽話里的彈舌音：AV22913633

Альвеолярные дрожащие согласные?— согласные звуки, встречающиеся во многих языках мира. Всего их четыре, у них общее место и способ образования. Эти звуки различаются по типу фонации и шумности/сонорности.

The?voiced alveolar trill?is a type of?consonantal?sound used in some spoken?languages. The symbol in the?International Phonetic Alphabet?that represents?dental,?alveolar, and?postalveolar?trills?is ?r?, and the equivalent?X-SAMPA?symbol is?r. It is commonly called the?rolled R,?rolling R, or?trilled R. Quite often, ?r? is used in phonemic transcriptions (especially those found in dictionaries) 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 ?r? 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.[1]?Languages where trills always have multiple vibrations include?Albanian,?Spanish,?Cypriot Greek, and a number of?Armenian?and?Portuguese?dialects.[citation needed]

People with?ankyloglossia?may find it exceptionally difficult to articulate the sound because of the limited mobility of their tongues.[2][3]
