Calling/ordering/requesting somebody in his/her language is Called Mantra.

When a Mantra( a set of particular words in a particular configuration and rhythm by chanting which one can fulfil one's wish) is chanted according to the proper Tantra( method to perform a worship in a systemised way), the sound vibrations gather force from the Yantra( a geometric figure inscribed on a metallic plate or paper and is the confluence of the powers of the concerned God) and after reflecting from its surface spread out into the universe and reach the concerned God.

A mantra (Devanaagarii मन्त्र) (or mantram) is a religious or mystical syllable or poem. Their use varies according to the school and philosophy associated with the mantra. They are primarily used as spiritual conducts, words or vibrations that instill one-pointed concentration in the devotee. Other purposes have included religious ceremonies to accumulate wealth, avoid danger, or eliminate enemies. Mantras originated in the Vedic religion of India, later becoming an essential part of the Hindu tradition and a customary practice within Buddhism, Sikhism and Jainism. The use of mantras is now widespread throughout various spiritual movements which are based on, or off-shoots of, the practices in the earlier Eastern religions.

Mantras are interpreted to be effective as sound (vibration), to the effect that great emphasis is put on correct pronunciation (resulting in an early development of a science of phonetics in India). They are intended to deliver the mind from illusion and material inclinations. Chanting is the process of repeating a mantra.
