NeatSpeech is a plugin for OpenEars that adds fast, higher-quality speech synthesis (TTS) including multithreaded speech queueing to speak very long phrases without any lag. It uses HTS voices which are ideal for mobile applications due to their diminutive file size, great processing speed and improved speech quality over the default Flite voices. All TTS is performed offline so absolutely no network connection is required. License is for integration with one app (you can sell unlimited copies of the app). Drag and drop the plugin right into a working OpenEars installation! Before purchasing, please try out the free demo of NeatSpeech first (demo is identical to licensed version, but has different license terms and times out after a few minutes).
