A piece of advice for voice performance:

• Perform all the podcast/screencast in one shot if possible.
• Otherwise, take many shots(5 to 10), for every 2 to 5 sections(all performed on the same session.)
• When you start the editing session, the best shots from the many takes will be used to mold the master track(by uniting the best takes of the chronological sections)
• Make sure your surroundings will stay quite for a significant amount of time.
• Only perform with adequate equipment.
• Apply the least amount of equalization and compression.
• If you slip words or err, don't stop, rather continue by repeating what you missed/erred.
• Take time to relax, the tenser you are the worse the performance will be.
• If the speech's pace is fast and relentless, take a deep breadth before starting.
• Place sound echo blockades, like sheet and clothes around walls and tables.
• Be happy. Sadness or unfeelingness is transmitted through the voice.
• Honey, yogurt and aloe vera are excellent throat cleansers.
• Sit or stand in a comfortable position.
• Script reading will highly enhance your fluency.
• Avoid scripts if it is a quick podcast/screencast.
