'Jarnal', and 'Rapid Speech'

Jarnal

Jarnal is an open-source application for note taking, sketching, keeping a journal, making a presentation, annotating a document -- including .pdf -- or collaborating using a stylus, mouse or keyboard. It is similar to Microsoft Windows Journal and to the earlier Mimeo whiteboarding and Palm notepad applications.

Rapid Speech

Rapid Speech is a very different, free text-to-speech (TTS) program. Instead of using synthetic voices, Rapid Speech converts text to speech/sounds by combining audio clips (MP3).
