The text of the talbiyah is:

Labbaika Allahomma Labbaik. Labbaik La Shareeka Laka Labbaik. Innal-Hamdah, Wan-Nematah, Laka wal Mulk, La Shareeka Laka. In Arabic لَبَّيْكَ اللَّهُمَّ لَبَّيْكَ، لَبَّيْكَ لاَ شَرِيْكَ لَكَ لَبَّيْكَ، إِنَّ الْحَمْدَ وَالنِّعْمَةَ لَكَ وَالْمُلْكَ لاَشَرِيْكَ لَكَ

IPA transcription:

læbːæɪk allˤaːhʊmːæ læbːæɪk læbːæɪkæ læː ʃæriːkæ lækæ læbːæɪk ʔĩnːælħæmdæ wæːnːɪʕmætæ lækæ wælmʊlk læː ʃæriːkæ læk

translated as:

"Here I am at Thy service O Lord, here I am. Here I am at Thy service and Thou hast no partners. Thine alone is All Praise and All Bounty, and Thine alone is The Sovereignty. Thou hast no partners."

The Shia version of the talbiyah is exactly the same as the Sunni one but ends with an extra "Labbaik."
