-//by Richard Russell, October 2016//\\ \\  The supplied example program **SPEAK.BBC** outputs the speech synchronously, that is **PROCspeak()** does not return to the caller until the speech output is complete. That will often be what is wanted, but in some circumstances you may wish to get on with doing something else while a phrase is being spoken. The programs below illustrate how that may be achieved; the first uses the **ActiveX** (COM automation) approach used in SPEAK.BBC and the second uses direct calls to the **SAPI5 COM objects**.\\ \\
