She’s a former Hollywood star and now British royalty, but the voice of Meghan Markle is a turn off when it comes to which celebrities Aussies would choose to be their voice assistant, according to a new study.

While the Duchess of Sussex ranked as having the least favoured voice, the soothing southern drawl of actor Morgan Freeman topped the list of celebrities Australians would choose to be their assistants.

The study called ‘The Voice of Us’ is the most comprehensive ever undertaken in Australia and included the online research of more than 2000 Australians aged 15+ overlaid with census data from the Australian Bureau of Statistics, to gauge the increased popularity and use of assistants and smart speakers including Apple’s Siri, Google Assistant, Amazon's Alexa and Microsoft’s Cortana.

The second most popular celebrity voice assistant after Freeman was Ocean’s Eleven star George Clooney, with the Scottish brogue of former James Bond actor Sean Connery third.

Australia’s own Nicole Kidman - the only woman to make the top 10 - ranked as the fourth most popular voice, with the dulcet tones of global treasure and environmentalist David Attenborough at five and Samuel L. Jackson at six.

The voice of US President Donald Trump was rated as the seventh most popular with Aussie heartthrob Chris Hemsworth coming in at eight. John Cleese and The King, Elvis Presley, rounded out the list at ninth and 10th respectively.

In addition to the Duchess of Sussex vocal assistant turn off, Aussies also least wanted to hear from PM Malcom Turnbull (second), Kardashian star Kylie Jenner (thirrd), convicted sex offender Bill Cosby (fourth) and British footballer turned model David Beckham (fifth).

Freeman’s voice topped the preferred voice list for both men and women, but for men the voice of Darth Vader, James Earl Jones, was second; Arnold Schwarzenegger (third); Samuel L. Jackson (fourth) and George Clooney (fifth).

For women, Sean Connery was second; Nicole Kidman (third); George Clooney (fourth) and David Attenborough (fifth).
