Areas of Speaking Voice Coaching

  • Voice Control - Learn the basics of vocal tone and control including breath support, resonance, projection, and elimination of unpleasant voice qualities (i.e. nasality, too high-pitched, or throatiness). Your voice will sound deeper, fuller, more powerful, and beautiful. You will love your new voice!
  • Diction - Articulation of consonants eliminates mumbling and creates clear, distinct speech. Formerly called elocution, diction is often all non-native professionals need to make their speech understood easily.
  • Vowel Pronunciation - Standard American pronunciation of vowels reduces regional dialects and foreign accents. Correcting pronunciation to Standard American requires a longer process, but worth the effort if you are an actor, broadcaster or business professional doing business where other's perception is important.
  • Vocal Color - Learn to put inflection and emotion in your voice to influence others. Learn the secret of "coloring" your voice so others feel your message.
  • Speaking Clearly for Foreign-Born Professionals - While it is not necessary to eliminate a foreign accent, it is important that listeners be able to understand your speech. Learn to pronounce sounds of American English in order to be understood more clearly in professional and personal situations.

"Learning to be comfortable as the center of attention has improved my business confidence in both small gatherings and in front of groups. But what really changed my speaking skills for the better was learning to think on my feet by telling stories, asking questions, and “stringing these beads together” to make interesting presentations."

"I want to thank you for teaching me to challenge and overcome my fears through the “Stage Fright/Natural Presence” class and then practicing what I learned with the follow-up session, “Telling Stories/Sharing Wisdom.” Not only were these two classes valuable to my career because they gave me new insight into how I function and respond when called upon to speak, they validated perceptions about myself ..."
