Among the thousands of voiceless animals goddess swaraswati awarded a precious gift to humans that's The Voice.According to vedas there is four kinds of voices that a human can speak .
1.Para
2.Pashyanti
3.madhyama
4.vaikhari
Vakhiri is type of sound that is simply used by humans in daily talk ,chatting with some one ,answering a question etc.
While Madhyama is sound that a human speaks when he is unconscious state .The Madhyama mode refers to chanting which occurs automatically. It is so named as it is the intermediate stage between the Vaikhari and Pashyanti modes.
Pashyanti in Sanskrit means "that which can be seen or visualized".On the stage of pashyanti-vak, speech is intuitively connected to the object. There is near oneness between the word and the experience described.
Para-vak is the transcendent sound. Para means highest or farthest, and in this connection it indicates that sound which is beyond the perception of the senses.
Para-vak is also known as "rava-shabda" - an unvibratory condition of sound beyond the reach of mind and intelligence (avyakta), only to be realized by great souls, parama-jnanis.
