# Speech Recognition

With HaloCode's microphone and built-in Wi-Fi, we can make a simple speech recognition application. The internet enables HaloCode to use Microsoft's speech recognition service. You need to sign in/up to mBlock 5 to connect your HaloCode to the internet.

**Sign in to mBlock 5**

HaloCode needs to connect to the internet to use online speech recognition service. We need to sign in to mBlock 5 first.
