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.
Apart from gaining a good impression of you, a clear and professional voicemail greeting is essential for negating any possible concerns the caller may have that you are the correct person to speak to, and will give them the information they need to leave you an effective message in return.

Consider adding 'You can also email your query to us at [insert email address here]. These queries will be answered within [insert time frame].' Again, if you intend to make a promise to your customer in a voicemail, ensure you keep it.
