Mimic is a fast, lightweight Text-to-speech engine developed by Mycroft A.I. and VocaliD, based on Carnegie Mellon University’s FLITE software. Mimic takes in text and reads it out loud to create a high quality voice. Mimic's low-latency, small resource footprint, and good quality voices set it apart from other open source text-to-speech projects.
