We have learned some basic sound and voice processing. We also explore several sound and speech modules to integrate into your IoT project. We built a program to read sound intensity level at the first. Then, we build programs with utilizing EasyVR and EMIC 2 modules for voice commander and Text-To-Speech program. The last topic, we make our Raspberry Pi board speak something.
The next chapter we will learn how to integrate our IoT project with cloud technology as back-end computing center.
