Altering text attributes in a text-to-speech converter to change the output speech characteristics

摘要

Allowing users to modify and improve the output of a text to speech synthesis system with the use of a graphical user interface where font, colour and position are used to represent the requested acoustic features. For example, increasing the font height increases the speech amplitude, spacing letters closer together increases the speech output rate or different colour speech is indicative of different emotions to be used. This allows manipulation of the text to achieve the desired output speech characteristics without having to use special studio techniques. The user can use an iterative process to further refine the speech output.
