# fastspeech_squeezewave
Integration of Fastspeech Text to Mel generation and fast Vocoder Squeezewave ( CPU only).
This is one of the fastest TTS solution.


Code from 

https://github.com/xcmyz/FastSpeech

https://github.com/tianrengao/SqueezeWave


Put Model in Squeezewave from 

https://drive.google.com/file/d/1RyVMLY2l8JJGq_dCEAAd8rIRIn_k13UB/view?usp=sharing 

and rename it Squeezewave.pt ( select based on quality and size tradeoff)
