Siri Voice Issues

I have just noticed an issue when using Siri to read out a web page or email.

I am in the UK, with all my settings set to UK.

Siri & Search

Language - English (Unitek Kingdon)

Siri Voice - British (Voice 1) (female)

When I do a 'hey Siri' request for the weather etc., then it gets read out in the correct voice.

However, if I am in Safari and then swipe down from the top with two fingers, it reads it out in an America female voice (I think Voice 4).

If I ask Siri to read out my last text message, that is with the correct voice, It only appears to to be an issue I swipe down with 2 fingers,

Is this a bug in IOS or is there a setting that I need to change?

Regards

Trevor
