High quality, lightweight and adaptable TTS using LPCNet

Understand

We present a lightweight adaptable neural TTS system with high quality output.

• The system is composed of three separate neural network blocks: prosody prediction, acoustic feature prediction and Linear Prediction Coding Net as a neural vocoder.
• This system can synthesize speech with close to natural quality while running 3 times faster than real-time on a standard CPU.
• The modular setup of the system allows for simple adaptation to new voices with a small amount of data.
