This is not applicable for all company,a proper review and capability test is important before you're going to outsource your project.If you take example of few corporate giants like Amex, Motorola, Boeing, Ingersoll Rand, Avon, GXS (spin-off of GE), Daimler/Chrysler, and Citigroup, HCL who have opted for outsourcing support to India and performing very well through their highly trained in house staff employed locally. The selection and recruitment procedures for those employees are very stringently performed and after going through different screening process including voice test procedure like diction, modulation and ascent of english language and its fluency. Those outsourcing companies ONLY select most competent person matching with their standards and requirement. Overall after appointing their staff they also provide continuous in-house training to improve their effectiveness in communication matching with international standard.
If you check the stats percentage growth for only international voice business in India there has been growth of 25% - 30% per year in international voice business itself.
