If you aren’t sure, have a friend listen to it and give you pointers. It’s always disorienting listening to your own voice, so you might not be able to catch if you sound weird because you’re hearing your voice or because you are actually speaking in a strange manner, but someone who knows you well will be able to clear it right up.
When clients or customers want to learn more about your business, oftentimes after checking out your website and social media, if they have further questions regarding your products or services, they’ll pick up the phone and call.

It may sound silly, but the tone in which you say something can either play the professional status up, or it can bring it down. You can’t change what your voice naturally sounds like, but you can work on controlling it to make sure you sound calm and collected when recording your message.
Humor also leaves a lot of room for misinterpretation—which subsequently weakens sincerity and authority. A caller can be very turned off by merely misinterpreting your joke. Why take this risk? Additionally, this could even cause callers to question your character. Say, for example, the president of a company’s mobile phone voicemail greeting was funny. What’s to happen if the caller didn’t like or get the joke? What if they found it offensive? Another scenario is that a caller is reaching out to you for the first time—i.e. they have no idea regarding your personality. What next? The point is, with this type of greeting, humor is bound to be more divisive so just avoid it altogether. c. Poorly Pacing Your Message and Bad Time Management: Don’t speed through your message. Speak clearly so callers know what to include in their message and when to leave the message. At the same time, don’t drag your message out. No one wants to sit through a diatribe. Just get to the point clearly.
