Thanks for your response. As I am a school Assistant Principal, my voice is of the utmost concern. In class teaching, I can never do without a microphone but in daily contacts with my colleagues or in meetings, it is very irritating that I don't know the state of my voice because it varies so much. It could be clear a second ago and then went very raspy in the next second.I need to sip water throughout the day.I anticipate the situation may worsen on the dry winter days. This has posed ample stress on me. My friend who has oral cancer suggests my consulting a speech therapist. Do you think it will help?
