Voice flute

The voice flute (also the Italian flauto di voce and the French flûte de voix are found in English-language sources) is a recorder with the lowest note of D4, and is therefore intermediate in size between the alto and tenor recorders.

Although sometimes regarded as a small tenor, a tone higher than the usual one in C4,[1][2]) it was treated historically and is most often in modern times described as a large alto.([3][4][5][6][7] Though it has been speculated that the name might refer to the instrument's range, which is roughly equivalent to that of the soprano voice, the origin of the term "voice flute" is obscure.[8][5])

Revived in the early twentieth century along with other sizes of recorder, it is used today as it was in the eighteenth century[not verified in body]—as a substitute for the transverse flute—though it also has a small repertoire of music composed specially for it, from both the Baroque and modern periods.
