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

@@ Can someone try on RPI (3 or 4 ) and update me timing information

Code from 

https://github.com/xcmyz/FastSpeech

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)

# Running Infernce
1. cd FastSpeech ; run_inference.sh

2. cd SqueezeWave ; run_inference.sh

This generate wave file.

# Example Run(Single CORE CPU)
