Siri consistently misspells 'Bangkok' as 'Bangcock' when dictating

When dictating, Siri more often than not spells Bangkok as “Bangcock’. What’s up with that? There is no other spelling except the correct one: Bangkok.

How can I correct this. With all the AI out there, mistakes like this should be a thing of the past.
