PDsay is a software application specifically developed to speech-enable a
Pocket PC. Not only does it provide voice interaction with the Personal
Information Management (PIM) tools, it also uses ScanSoft's award winning,
human sounding Text-To-Speech (TTS) technology to read appointments,
contacts, tasks, and e-mail messages for eyes-free access to information. 

PDsay offers hands-free access and control of PDAs. Productivity and
efficiency is vastly improved by reducing the need to use the stylus when
walking through menu commands. PDsay offers direct voice access to
information and automatic notification even while occupied with other tasks.
There’s no need to look at the Pocket PC  while retrieving data.
