Starting with the Windows IoT Core 14986 release, Microsoft has added the Cortana voice assistant feature. Before, we could only use local speech recognition, and we needed to write the application to download it to the device. From now on, Microsoft has integrated the Cortana voice assistant from the system level, enabling users to start Cortana and interact with Cortana in real time with system settings. Let's try the process of using Cortana as a Windows IoT core device with

Introduction
Some time ago, someone posted a Post saying that Raspberry Pi could send FM radio signals, so they all played around and found that the effect was good. So they wanted to expand their functions.
Fmemission functions implemented on the Internet have limitations:
Only files in WAV format can be played, and wav files must be16 bits 22.5 kHz mon
