ephb / glados-tts

A GLaDOS TTS, using Forward Tacotron and HiFiGAN. Inference is fast and stable, even on the CPU. A low quality vocoder model is included for mobile use. Rudimentary TTS script included. Works perfectly on Linux and Windows. CLI only.

GLaDOS Text-to-speech (TTS) Voice Generator

Neural network based TTS Engine.

If you want to just play around with the TTS, this works as stand-alone.

nix-shell --run 'python glados.py'

the TTS Engine can also be used remotely on a machine more powerful then the Pi to process in house TTS: (executed from glados-tts directory

nix-shell --run 'python3 engine-remote.py'

Default port is 8124 Be sure to update settings.env variable in your main Glados-voice-assistant directory:

TTS_ENGINE_API			= http://192.168.1.3:8124/synthesize/

Description

The initial, regular Tacotron model was trained first on LJSpeech, and then on a heavily modified version of the Ellen McClain dataset (all non-Portal 2 voice lines removed, punctuation added).

• The Forward Tacotron model was only trained on about 600 voice lines.
• The HiFiGAN model was generated through transfer learning from the sample.
• All models have been optimized and quantized.

Getting Started on Windows

Grab the latest version of espeak-ng for Windows. https://github.com/espeak-ng/espeak-ng/releases

Install Requirements with pip

Navigate to the folder of the project and run:

pip install -r requirements.txt

Set Path for Phonemizer

Phonemizer needs to know the path to your espeak installation.

Open an elevated command prompt and enter the following if you installed espeak.-ng in the default location:

setx PHONEMIZER_ESPEAK_LIBRARY "c:\Program Files\eSpeak NG\libespeak-ng.dll"
