Nintendo DS Microphone: Does It Have One? Original DS/Lite No, DSi/3DS Yes

Original Nintendo DS / DS Lite: No Built-In Microphone

The DS and DS Lite lack a microphone. Games that appear to use voice (e.g., Nintendogs bark recognition) actually use the touch screen (blow detection via pressure/airflow on screen) or button inputs.

DSi / 3DS Family: Have Microphone

• Nintendo DSi / DSi XL: Built-in mic (front hinge). Used in WarioWare: Snapped!, Flipnote Studio, DSi Sound.
• Nintendo 3DS / 2DS / New 3DS: Mic at bottom-left. Used in Tomodachi Life, Pokémon X/Y (voice chat), Kirby: Planet Robobot.

If your DS game “uses a microphone,” it’s simulating it via touch or buttons.
