The Source Ruckus Packager (SRP) is a lightweight, yet fully-featured package manager. The target audience for this packager is not the big-time distribution developers, but a single user rolling his or her own at home (or in a small office). This utility is part of the Source Ruckus project.
Gespeaker is a GTK+ frontend for espeak. It allows you to play a text in many languages with settings for voice, pitch, volume, and speed. The text can also be recorded to a WAV file for future listening. Gespeaker supports the speech synthesizer MBROLA for a better speech experience.
