Generate unique, emotional astromech vocalizations with the press of a button! The Astromech Vocalizer is a fully functional AI. The software is powered by advanced research into the speech patterns and emotional logic of R2-D2. Users can design their very own astromech voice by customizing the droid's grammar, vocabulary, accent, emotional nature, pitch, and effects. Whether designing a voice for an existing droid without vocal precedent or a droid of your own creation, the Astromech Vocalizer gives life to a never-before-heard astromech. After customizing a voice, press an emotional stimulus button and the astromech will respond. Its emotions will shift based on the personality you selected. It will then vocalize its new emotions. Each vocalization is unique. A sophisticated algorithm assembles the astromech's speech "syllable" by "syllable." Billions upon billions of rules dictate how each sound should be selected, processed, timed, and sequenced to achieve based on R2-D2's emotional and grammatical precedent. For more control, use the Script panel to create a vocalization manually. The software's grammatical AI provides canonically-appropriate recommendations to guide you towards a coherent vocalization. Then store your custom vocalization to memory where it can be recalled either verbatim or with organic, AI-powered variation. This software is entirely free and contains no advertisements or in-app purchases. For more information on the Human-Cyborg Relations project, please visit humancyborgrelations.com
