You need to train the module first before recognizing any voice command

A 6-band resistor is like a 5-band resistor but includes a temperature coefficient band (the 6th band)

A HIGH on either of the input enables forces the outputsHIGH

the U/D input should be changed only when either CE or CP is HIGH

When LE is LOW, the state of the segment outputs (a to g) is determined by the data on A to D. When LE goes HIGH, the last data present
