This type of service can be very beneficial as users are still able to craft their own messages, while a professional reads them. In doing so, companies can spend more time on the scripting process, making sure the text conveys everything they want it to. As such, companies may bring in expert teams to draft, revise, and/or finalize the script itself. The bottom line is you can take more time to get the words right. Additionally, in working with a professional voice talent, you are ensuring your words have the utmost impact—i.e. the words are read perfectly with the right tone, resonance, pacing, etc.
"You see a lot more people working on collaboration technologies where you can share and exchange information in more social media-like contexts," he says.

For example, a message like, “Hi, this is Jim. You know what to do.” Well, not everyone is going to know what to do—i.e. they won’t leave you inclusive information. Additionally, they may not leave you a message at all. Aside from this, humor can again be detrimental to your message, this time lending itself to ambiguity and costing you clarity. For example, if a message read, “Hi this is Jim, sorry I can’t answer your call right now. Please leave your name and number and I’ll call you as soon as I can, but you already knew that right? Do I need to tell you what to do?” This is worse than the previous example as this is confusing and can also come across as rude and unprofessional. Complicating a greeting with phrasing like this is sure to cause some harm. e. Ignoring Personality & Identity: Don’t use computer generated greetings. Some users leave default messages (‘you’ve reached the voicemail box of 777-777-777, please leave a message). Believe it or not, even this can cause problems. Callers may be unsure if the voicemail box belongs to you; therefore, they don’t leave a message. Also, some may even be uncomfortable leaving information through a message in a nameless voice message box. As such, impersonalization can cause ambiguity, which again can hurt the effectiveness of your voice message system. This doesn’t mean you have to make an elaborate greeting if you don’t want to, just insert your voice and name so at least callers know they’re calling the right person.
You should script out your greetings, rehearse, and find a tone of voice that is reflective of your professionalism and your company’s personality. If applicable, your tone and your message should take into account that certain industries and companies are more conservative than others.
