lt-Speech-components

What

• Added SpeechRec component to recognize a word and update game input value w/ it. Works with the game mechanics already set up.
• Added SpeechSynth component to create a verbal prompt for the word-type required.
• Added play and listen to game input state to manage when the vocal prompt is on and off and start speech recognition.
• Added mic and speaker icons in an asset folder
• Added toggle to app state to initiate a verbal game or not. Can be toggled mid-game.

Next

• Some life-cycle niceties should be added to ensure we are not re-rendering unnecessarily.
• convert speechsynth to a stateless component.
