Put yourself in your listener’s shoes. Have you ever tried listening to someone on the phone who’s just talking so fast? Apart from not understanding what they have to say, you could also be tempted to just cut the call and drop it. Or, it becomes an inconvenience to your listeners for them to have to rewind your message frequently just to understand the message.
As greeting messages should reflect your mood and your personality, they must be recorded with utmost care and with the right choice of words. Here are a few examples which you can make use of while recording your own greeting messages.

The phone you use to record your greeting – and your surrounding – can turn your carefully scripted greeting into an unprofessional mess. Background noise is terribly distracting, so choose a quiet room or parked car to make your call. Landlines, or a “wi-fi enabled” cellphone call, can provide much better connection quality than a standard cellphone. If you must use a cell phone, be sure to use a high-quality headset for the best clarity.
