The Voder was an early attempt at speech synthesis developed by Bell Telephone Laboratory for the 1939 New York World's Fair. Controlled by hand, the operator manually forms each syllable using complex button sequences, and it would take about a year of practice to able to produce fluid speech. This website allows you to put yourself in the shoes of the women who taught themselves to operate Voder.
It's recommended that you use NVM to manage your Node version:
# brew install node nvm (or whatever package manager is relevant to your system)
nvm install ; nvm use
npm install ; npm startThis command will dynamically rebuild the app on source file changes. If you are maintaing your own fork, then deploying new versions of the app to GitHub is similarly easy:
npm run deploy
