What’s it like to wake up with a brand new voice? For those with foreign accent syndrome, this is their reality. Patients who develop this rare speech disorder start speaking in a brand new accent that they often have no connection to.

So how does losing the voice you’ve known your entire life shape, or break, your identity?

Presenter Ella Hubber speaks to Althia Bryden, who developed foreign accent syndrome last year, and Sarah Colwill, who has lived with the condition for the past 15 years. They share the deep impact it has had on their identity and connection to those around them.

And to understand what is happening in the brain to cause this complete change in accent, and whether it’s really even an accent at all, Ella speaks to professor Nicholas Miller, who has been unpicking the mystery of foreign accent syndrome for decades. Also, professor Stefanie Keulen shares that there are actually multiple types of the condition.

Even though foreign accent syndrome is rare, it is found around the world, can affect anyone, and highlights just how deeply our voices influence all aspects of our lives.
