Added command line parser to allow user pass voice parameters from command line

Added Command line parser to allow users pass voice parameters from command line

parameters that can be passed by users are
age of the speaker , gender of the speaker , language of the speaker and talk phrase of the speaker to speak.

An actual example of a user input after these changes is:
speechTest.exe -g Female -a Teen -c en-US -t "Hello World"

the speaker will be a teen female who will speak the phrase "Hello world" in English language
