Node Live Text-to-Speech Starter

Get started using Deepgram's Live Text-to-Speech with this Node demo app.

The flow of this sample is:

1. A websocket is opened from the UI to the backend Javascript component
2. Text is sent over a websocket to the backend component
3. If a connection has not been established to Deepgram, create a websocket connection using the Javascript SDK and send the text to convert to audio
4. An audio byte response with synthesized text-to-speech is returned and forward back through the WebSocket created by the UI
5. Those audio bytes are then played by the media device contained within your browser
