3. Press again to play the currently recorded sound, and play the recorded sound once when the button is triggered.

How does a voice module work?

Voice recognition is a technique that facilitates a natural and convenient human-machine interface using the voice recognition module. It extracts and analyses voice features of human delivered to a machine or computer through the mic.

Can Arduino record sound?

Introduction: Arduino (Mega) Audio Recording The audio file can be played back on a standard audio application or analysed byte by byte. The sample rate is 9.4 KHz and the wav file output 8 bit, mono. Whilst not hi-fidelity, the sound quality is perfectly adequate. The recorded wav file can be saved as tabulated data.
