2. Internal structure and processing capacity: The MCU contains the processor, memory, input and output interfaces and other components, which can be programmed to control its behavior. It can perform various tasks and has high processing power. Voice module usually contains specialized audio processor, audio memory and audio interface components, its processing power is relatively low, mainly for speech-related functions.

3. Application: SCM is widely used in various electronic equipment and systems, such as home appliances, communication equipment, industrial control, etc. It can be programmed to achieve different functions and applications. Voice modules are usually used in products that require speech synthesis, speech recognition or audio playback functions, such as voice assistants, voice control devices, etc.

4. Interface and communication: MCU usually has a variety of communication interfaces, such as serial port, parallel port, SPI, I2C, etc., which can exchange data and communicate with other devices. The voice module is usually connected to other devices through a specific audio interface (such as the 3.5mm audio interface), and the audio signal input and output through the interface.
