Hello, and welcome.
Note that I have moved your thread to our Pronunciation section.
Please do not use introductions to your questions. Just go ahead and ask them. Also:
1- "dearest" is only used with people you are very close to.
2- We are not instructors.
Note also that "instrument" in your title is not correct. Use "software" instead.
I don't know of any such program, but I'm sure they exist. Perhaps other members can offer some help. You can always make short recordings on vocaroo.com and post the links to this section of the forum.
