تبدیل اعداد به حروف و تابع پخش فایل صوتی

سلام دوستان .
من میخوام چندین فایل صوتی رو توی یه برنامه وارد کنم (به عنوان یه تابع ) و چندین بار در برنامه این فایل های صوتی رو تابع هاشونو فراخوانی کنم .
میتونید کمکم کنید ؟
این کارو برای خواندن اعداد میخوام .
کامپلر هم vs2010 هستش و زبانی هم که دارم برنامه مینویسم c++.
در ضمن من برنامه ی تبدیل اعداد به حروفو نوشتم که بعدا اون حروف ها رو تبدیل به فایل صوتی می کنم.
تقریبا هم کامله فقط نمیدونم مشکلش کجاست که خروجی مد نظر رو نمیده .
میتونید کمکم کنید و مشکلشو رفع کنید ؟
