No, it comes with a fixed melody. Different part numbers represent different tunes.

Use a transistor amplifier circuit (e.g., using 8050 or BC547) between the output and the speaker.

Only small piezo buzzers. For normal speakers, external amplification is required.

It’s designed for short, triggered playback — typically one-shot on power-up.

ISD series voice record/playback ICs or microcontroller-based sound systems are preferred for programmable output.
