Not in adults. Children often avoid consonant clusters by inserting a schwa. My daughter had a soft toy called /'rǝʊzǝmǝri:/ (the name 'Rosemary' has only three syllables).
(I assume you're aiming for an Am Eng accent. In Br English an /'ɑ:mlət/ is a (not very common) clothing accessory - an 'armlet'). The more commonly used word is 'armband' - worn, for example, at football matches and funerals; maybe there's a difference - no doubt someone will tell me!)
