The voiced alveolar plosive is a type of consonantal sound, used in some spoken languages. Its manner of articulation is a voiced glottalic plosive or stop. Its place of articulation is alveolar. The symbol used by the International Phonetic Alphabet to represent this symbol is [d]. The [d] sound in English is spelled with the same letter 'd', as in dig or fad.

The [d] sound is a common sound cross-linguistically. Many languages have at least a plain [d], and some distinguish more than variety.
