| To help with his breathing difficulties he needed an operation called a tracheotomy, where a tube is placed into the windpipe through the neck, effectively bypassing the mouth and nose. | To help with his breathing difficulties he needed an operation called a tracheotomy, where a tube is placed into the windpipe through the neck, effectively bypassing the mouth and nose. |

| But then a computer expert in California, called Walt Woltosz, heard of Prof Hawking's plight and sent him a computer program he had written, called Equalizer. | |
| This allowed Professor Hawking to select words from a series of menus on the screen, controlled by a switch in his hand. | |

| Prof Hawking says: "One's voice is very important. If you have a slurred voice, people are likely to treat you as mentally deficient: 'Does he take sugar?' This synthesiser is by far the best I have heard, because it varies the intonation, and doesn't speak like a Dalek. | |

| More recently, patients with MND are beginning to be offered the option of voice banking - stockpiling recordings of themselves before their speech declines, so that when they need to use a computerised system it will be their own voice rather than a computerised version that is used. | |
