How to change speech recognition configuration after initialization of the speech recognizer

Question

Hi, I was experimenting with microsoft speech sdk and for my use case scenario I have to dynamically change some properties inside the configuration, for example:

PropertyId::Speech_SegmentationSilenceTimeoutMs

Is it possible to do it somehow? I.e. at various time points I need to change this property on different values. Is it possible to do it without doing reinitialization of the speech recognizer? I'm using c++ programming language.

Thanks!

@Faris Lemes Welcome to Microsoft Q&A Forum, Thank you for posting your query here!

In the Microsoft Speech SDK for C++, the method to set a property is SetProperty

public inline void SetProperty (PropertyId propertyID, const std::string & value);

More info here.

In the Microsoft Speech SDK, the SpeechRecognizer class has a Properties member that is a collection of properties and their values. You can use this to change the properties of the SpeechRecognizer after it has been initialized. More info here and here.

Here is an example of how you might do this in C++:

// Assuming you have a SpeechRecognizer object named recognizer 

auto properties = recognizer.Properties; 

properties.SetProperty(PropertyId::Speech_SegmentationSilenceTimeoutMs, "new_value");

In this code, "new_value" should be replaced with the value you want to set for the Speech_SegmentationSilenceTimeoutMs property.

Hope this helps. If you have any follow-up questions, please let me know. I would be happy to help.
