Whether you are a new graduate searching for that first “real” job, recreating your career through a job change, or in your own business and making those dreaded cold calls, you will find yourself in the position of trying to get your foot in the door so you can sell yourself and your skills. People spend a lot of time preparing résumés and sales copy, but often overlook the most important factor: their vocal résumés. Hiring officials often make their decisions on subconscious factors, including the image you project through your voice, and often they hear your voice for the first time on a voicemail message. Here are the top three tips to help you get your foot in the door by getting your voice in the door first—by leaving a powerful voicemail message.

1. Be Prepared! Recognize that the probability of reaching an actual person is rare, and you will most likely have to leave a voicemail message. Many women tend to ramble when they leave voice messages, then run out of time to leave their most important information, and rush through it. Prepare a brief, up to 30-second message that clearly states your name, contact information, and essence of your call. For example: “Hello. This is Julie Lexington calling, with Lexington Consulting Group. I am following up on the information packet I mailed you last Thursday, and would like to schedule an interview to discuss your needs and how our skills can be a fit for you. I can be reached at area code 302, 555-1234 or by email at Julie@Lexingtonconsulting.com. Thank you and I look forward to talking soon. Again, my name is Julie Lexington, and I can be reached at 302, 555-1234.” Leave your name and number twice—once at the beginning and again at the end of your message. Another little tip: say “zero” instead of “oh” when giving numbers.

2. Practice It! You don’t want to sound like a paid telemarketer, reading a script. Your goal is to sound enthusiastic without sounding phony, to create an interest on the part of the hiring official to want to know you better. Practice reading through your prepared message, and make it conversational and personable. Don’t be afraid to smile as you speak!

3. Inflect Down! This is particularly important for women, who have a tendency to end every sentence on an upward inflection, making them sound unsure or tentative. End your sentences using a downward inflection to create an image of credibility and professionalism.

Bonus Tip: Get rid of your “Vocal Vices!” You know what they are—those irritating vocal habits that interfere with your communication. For example, filler phrases like “uh …” or “you know …” If you don’t know what your “Vocal Vices” are, just ask a close colleague or friend. Other people are usually much more aware of your vices than you are. You can also tape yourself as you make telephone calls or make a presentation. As you replay the tape, your “Vocal Vices” will become quite obvious. Once you are aware of them, they are much easier to control and eliminate.

You have a voice that is unique to you—a voice that can help you project a powerful image of confidence and credibility. Make it a priority to discover your authentic voice, and develop it into the voice that means business.
