The documentary MND and 22-Year-Old Me followed Lucy on her visit to Speak:Unique, a research project at the University of Edinburgh aiming to create personalised synthetic voices.
She was recorded speaking a selection of 400 sentences that include the various combinations of English speech sounds.
To generate the synthetic voice, a person’s voice is mixed with a base of other, donor voices.
Phillipa Rewaj, a Speech and Language Therapist, compares it to buying bespoke paint: a small amount of colour is added to a tin of the closest matching base paint.
For the best results, the person would record their voice before there has been any effect on their speech.
But if there has already been some impact on the speech of the person, it may be possible to ‘repair’ some of the voice by adding in higher levels of the donor voice.
