The word 'dh' is not a recognized word in written English. It is possible that it is a slang or abbreviated term used in certain contexts, such as in online messaging or in a specific region or community.

Here there is considerable disagreement between the other languages: Greek has voiceless aspirates (ph, th), Sanskrit has voiced aspirates (bh, dh), Latin has voiceless fricatives in word-initial position (f) and voiced stops in medial position (b, d), Slavic has voiced stops (b, d), and so on.
The voiced stops b and d in Sanskrit and Hindi also have aspirated forms that are usually transliterated as bh and dh.
(A stop is a consonant made with complete momentary stoppage of the breath stream some place in the vocal tract; voiced stops are those produced with the vocal cords vibrating, such as b, d, g. An aspirated sound is accompanied by a puff of breath, often written as an h, as in bh, dh, gh; an unaspirated consonant lacks this accompanying puff of breath).
The exact pronunciation of the voiced aspirates is somewhat uncertain; they were probably similar to the sounds transcribed bh, dh, and gh in Hindi.
In all Italic languages this f sound replaced the Indo-European voiced aspirated sounds (represented as bh, dh, gwh) in initial position.

In the United States the greatest success of wartime production was the very advanced 12-cylinder, water-cooled, 400-horsepower Liberty engine, developed for the DH-4.
For its own use the U.S. Army ordered the production of the two-seat British De Havilland DH-4 bomber and the American-designed Curtiss JN-4 Jennie trainer.
Characteristically, organizers of the first postwar airlines relied on stocks of inexpensive surplus military planes, especially bombers, such as the De Havilland DH-4, that could be modified to accommodate passengers and mail.
