+# Mimic 3
+
+A fast and local neural text to speech system for Mycroft.
+
+
+## Architecture
+
+Mimic 3 uses the [VITS](https://arxiv.org/abs/2106.06103), a "Conditional Variational Autoencoder with Adversarial Learning for End-to-End Text-to-Speech". VITS is a combination of the [GlowTTS duration predictor](https://arxiv.org/abs/2005.11129) and the [HiFi-GAN vocoder](https://arxiv.org/abs/2010.05646).
+
+Our implementation is heavily based on [Jaehyeon Kim's PyTorch model](https://github.com/jaywalnut310/vits), with the addition of [Onnx runtime](https://onnxruntime.ai/) export for speed. 
+
+
+### gruut Phoneme-based Voices
+
+Voices that use [gruut](https://github.com/rhasspy/gruut/) for phonemization.
+
+
+### eSpeak Phoneme-based Voices
+
+Voices that use [eSpeak-ng](https://github.com/espeak-ng/espeak-ng) for phonemization (via [espeak-phonemizer](https://github.com/rhasspy/espeak-phonemizer)).
+
+
+### Character-based Voices
+
+Voices whose "phonemes" are characters from an alphabet, typically with some punctuation.
