ISpThreadTask (SAPI 5.4)

Speech API 5.4
Microsoft Speech API 5.4


The ISpThreadTask interface simplifies thread-based operations. Clients can implement this virtual C++ interface to simplify the management of threads. SAPI provides coordination methods for starting, initializing, and stopping the thread. See the ISpThreadControl documentation for more information. Clients simply implement three methods which will be called on the allocated thread.

When to Implement

Use SpThreadControl objects to allocate threads for an object.

This is not a COM interface.
