Accents and RT

[zoink]

Silly question came to my head recently and it was how are people's accents handled by the ATC training process?

For example, and I use these only as examples; no other agenda, the accent of say a Newcastle born controller or a Glasgow controller or an Irish controller can be quite strong and in pressured RT situations I was wondering if the training process included some form of voice coaching for to enable the RT to be understood first time.

Thanks
