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.

Example: 'Thank you for calling [insert name here]. We're sorry we couldn't take your call this time. However, if you'd like to leave us a voicemail we will get back to you within [for example] 30 minutes of receiving this message. Alternatively, if you'd like to reach out by email you can do so at [insert email address]. Again, thank you for calling [insert company name]. We look forward to your message.'
