It didn't work for me because i noticed that my speech is different when talking to someone. Emotions play a big role and your pitch changes with certain sentences. Unnoticed you talk to everybody in a different way, and you kinda have to time it when you can talk. After someone is done with a sentence there is space for you to talk. You need to be close enough to someone or they won't hear and understand you, so when walking up to someone theres a certain timing when you're close enough. And when you're just doing a task it becomes just information that needs to be said and doesn't really acquire a timing or a pitch. Thats how i experienced speech therapy, hope this can help you.
