SAPI - How to stop all asynchronous speech tasks?
To stop all asynchronous speech tasks in the Microsoft Speech API (SAPI), you can use the ISpVoice
interface's Skip
method to skip the remaining speech data. Here's an example in C++:
cpp#include <sapi.h>
int main() {
// Initialize COM
CoInitialize(nullptr);
// Create an instance of SpVoice
ISpVoice* pVoice = nullptr;
CoCreateInstance(CLSID_SpVoice, nullptr, CLSCTX_ALL, IID_ISpVoice, (void**)&pVoice);
// Set up the voice parameters and speak some text asynchronously
pVoice->Speak(L"Hello, world!", SPF_ASYNC, nullptr);
// ... Additional speech tasks ...
// Stop all asynchronous speech tasks
pVoice->Skip(L"SENTENCE", INT_MAX, nullptr);
// Release the voice object and uninitialize COM
pVoice->Release();
CoUninitialize();
return 0;
}
In this example, we create an instance of ISpVoice
using CoCreateInstance
. We then use the Speak
method to start an asynchronous speech task. After performing any additional speech tasks, we call the Skip
method with the "SENTENCE"
type and INT_MAX
as the number of elements to skip, which effectively stops all remaining speech data.
Remember to include the necessary header files (<sapi.h>
) and link against the appropriate libraries when compiling your code.
Note that this example demonstrates how to stop speech tasks in C++ using SAPI. If you are using a different programming language or library, the method and syntax may vary.
