This paper reviews some recent developments in Text to Speech synthesis at Dolphin.  It will be of interest to those concerned with improving the experience, at work, and at home, for people who use speech as part of their primary access tool.  The latest Orpheus version 2, speech synthesizer includes the ability to speak with more natural sounding, concatenative voices, alongside the familiar synthetic voices; Orpheus is unique in including both types of voice in the same engine.  Concatenative voices are suitable for many applications beyond use by blind and visually impaired computer users.  They are often deemed easier to listen to, especially by intermittent users of speech.  The synthetic voices on the other hand, use little memory, are responsive and are intelligible at the fast talking rates often used by blind and visually impaired computer users.  
Their use can aid efficiency in many tasks for instance, in response to the demand for speech on portable devices; Dolphin has ported the Orpheus version 2 to Windows CE. Orpheus for Windows CE is now available from Dolphin as an SDK, and will be demonstrated on industry standard PDAs running Windows Mobile 2003 talking applications.
