For people who have lost the power of speech, the voice synthesiser is wonderful. All they have to do is type what they want to say on a lap top computer, and their words are changed into sound. However, when we speak, we use intonation and stress to give extra meaning to what we say, and up to now, computerised voices have not been able to do this. This makes it difficult to express things like urgency or irony. But new developments allow the user to add emphasis to what they are saying, choose a voice of the same sex and approximate age, and even to choose a similar regional accent.
