What is "spinvox"

SpinVox was a start-up company that is now a subsidiary of global speech technology company Nuance Communications, an American multinational computer software technology corporation, headquartered in Burlington, Massachusetts, United States on the outskirts of Boston, that provides speech and imaging applications. Initially, SpinVox provided voice-to-text conversion services for carrier markets, including wireless, fixed, VoIP and cable, as well as for unified communications, enterprise and Web 2.0 environments. This service was ostensibly provided through an automated computer system, with human intervention where needed. However there were accusations that the system operated almost exclusively through the use of call-center workers in South Africa and the Philippines.
