The Bangkok Voices was founded by their current conductor in 2005 with the aim to promote and broaden the choral repertoire among its members and the community. It has been receiving constant encouragement and support from Thai National Artist, Khunying Malaival Bunyaratavej. The choir is comprised of musicians, music teachers, students and music lovers with Mr. Alfred John de Veyra, a former member of world renowned “Philippines Madrigal Singers” who lay the foundation for the group as its first conductor and since 2007 onward, Dr. Kittiporn Tantrarungroj has been appointed as the conductor.

Since its foundation, the group has regularly performed and has quickly become recognized. Its regular performances aimed not only to introduce new standard choral repertoires to the public, but to educate its listeners. The group has commissioned numerous new choral arrangements of Thai music, giving a greater dimension to many local choir repertoires.

The Bangkok Voices musical renditions have spread out and are integrated into the repertoire of many Thai choirs which use them as a prototype for their own development. Besides ongoing regular public performances, the Bangkok Voices is frequently invited to participate in State functions. They have sung for high dignitaries visiting Thailand and they were frequently invited to participate in many international choral festivals in Southeast Asia and in Europe.

The choir's continuous improvement reflects in its national and international awards. In every choral competition, the Bangkok Voices always achieves a high level of recognition (see Awards & Recognition). Currently, they are recognized to be one of the finest choir groups in Thailand.
