This is a simple Text-to-Speech application that uses the Google Cloud Text-to-Speech Engine to synthesize natural-sounding speech with 100+ voices in multiple languages. It's written using a NodeJS API, with a very small single-page frontend. I've attempted to minimize dependencies to keep things simple.
Google Cloud Text-to-Speech enables developers to synthesize natural-sounding speech with 100+ voices, available in multiple languages and variants. It applies DeepMind’s groundbreaking research in WaveNet and Google’s powerful neural networks to deliver the highest fidelity possible. As an easy-to-use API, you can create lifelike interactions with your users, across many applications and devices.
To use this code, you must obtain your own Google Cloud SDK service account key with Google Cloud Text-to-Speech API enabled. Please see this link for instructions. This document assumes you've saved this credential file to ~/.config/gcloud.json
# git clone https://github.com/dragontek/gctts.git
# cd gctts
To run using NodeJS, you must first define the GOOGLE_APPLICATION_CREDENTIALS environment variable. Then you can simply install the node packages and start the application. Once it's running, you can visit the page at http://localhost:3000
# export GOOGLE_APPLICATION_CREDENTIALS=~/.config/gcloud.json
# npm install && npm start
By default, the docker image will set the GOOGLE_APPLICATION_CREDENTIALS environment variable to /root/.config/gcloud.json. You will need to either mount your service account key to that location or override the environment variable to point to yours.
# docker build -t gctts .
# docker run -p 3000:3000 -v ~/.config/gcloud.json:/root/.config/gcloud.json:ro -d gctts
- Transition from JADE to static HTML with jQuery
- Add SSML Editor or at at least tag substitution/recognition
Add better loggingAdd SSML supportImprove mobile layoutSeparate languages from voice selectionAdd country flags for localesBetter UI for voice dropdown
