In our simple Speech color changer example, we create a new SpeechRecognition object
instance using the SpeechRecognition() constructor, create a new SpeechGrammarList, add
our grammar string to it using the SpeechGrammarList.addFromString
method, and set it to be the grammar that will be recognized by the
SpeechRecognition instance using the
SpeechRecognition.grammars property.
const grammar = '#JSGF V1.0; grammar colors; public <color> = aqua | azure | beige | bisque | black | blue | brown | chocolate | coral | crimson | cyan | fuchsia | ghostwhite | gold | goldenrod | gray | green | indigo | ivory | khaki | lavender | lime | linen | magenta | maroon | moccasin | navy | olive | orange | orchid | peru | pink | plum | purple | red | salmon | sienna | silver | snow | tan | teal | thistle | tomato | turquoise | violet | white | yellow ;'
