I bought a CD of a lecture by the instructor from my voice training course at the NHK Culture Center. I highly recommend it for skill improvement as we head into the new fiscal year. For those who can speak well, the range of opportunities expands dramatically. Proper vocalization is fundamental, and as your voice improves, it becomes more enjoyable. Next, you'll work on correct word usage and intonation, adding expression to your speech. Communication becomes fun. Just by trying, your mindset will change. This tool is something you'll have for life. Easily improve your skills at home. It's also fun to have lessons with friends or in a group. Thank you.
