Nobody wants to listen to a long-winded voicemail. Keep your greeting short, simple, and concise. A voicemail message should pique a client’s interest and leave them looking forward to your call. Stick to the basics, explaining your company name, hours of operation, and when to expect a callback.
Being personable is key in having your caller look forward to receiving your callback. To do this, use different intonations in your voice to convey enthusiasm.

While a short recording may not seem like a place to win new business, the professionalism, courtesy, and clearness that you convey in your greeting will leave a favorable impression in a customer's mind.

In Australian English it’s pronounced with the vowel /a:/ like in ‘part’. Problems arise when people use the /ʌ/ vowel (like in ‘up’) instead of /æ/ or /a:/. If you do this is will sound like the worst swear word in English. Many non-native speakers often pronounce the vowel /æ/ more like /ʌ/ because they don’t have a vowel like /æ/ in their first language. Many speakers of European languages will do this (Spanish speakers and Italian speakers) and also speakers of Japanese and Korean. This problem with /æ/ also means that if you say the word ‘back’ in your voicemail greeting sample, you are likely to pronounce it more like ‘buck’. remember to pronounce word endings in English. Check you aren’t dropping any endings off or mispronouncing them.
