If you like to keep things simple, opt for a basic greeting. Most voicemail options allow you to record just your name, which lets callers know they’ve reached the right person.
The best text-to-speech voices don't sound robotic at all. Do a "text to speech" search in Google to explore your options. Type in your script and presto! You'll get an instant greeting with a natural sounding voice. You can select from a broad spectrum of male & female voices with any local or foreign accent you choose. LinkedPhone offers text-to-speech built right into our software. It's super popular and our users love it!

Simply speak into your phone or computer while recording a greeting with your business phone service. If you need to create your own audio file, the voice memo app on your phone should do fine.
I have a confession to make: I haven’t recorded a new voicemail greeting since 2014. In the past four years, I (hopefully) have become more articulate, poised, and self-assured. But hear my voicemail recording, and you’d think I was still new to the work world, a little unsure of myself — and probably not an authority. Obviously I need toupdate it. And if you haven’t changed your voicemail greeting in over a year, you’re likely in the same boat. After all, a professional voicemail recording boosts your credibility, makes you seem more competent, and encourages whoever’s listening to it to continue the relationship. A relatively unprofessional one — like mine, for instance — does the opposite: It encourages prospects, recruiters, and potential connections to run in the other direction. With that in mind, I’ve written 18 unique voicemail greetings for every situation. Pick your favorite, practice a few times, then record your new voicemail.
