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.
We suggest you create a script beforehand with the text of your message, and then read it while recording. Be sure to record away from background noises or distractions.

In order to ensure customer satisfaction, it is not only important how a business records their outgoing voicemail greeting, but also how they respond to incoming messages. It has been reported that most individuals do not mind leaving voicemail messages, but they can often become frustrated and disheartened when a business does not return their call in a timely manner or ignores the voicemail altogether.
