Adding voice to Scratch projects can make them more engaging and interactive. By using the text to speech blocks in Scratch, you can have your projects speak words or phrases. You can also use a microphone to record your own voice and add it to your projects.
There are many benefits to adding voice to Scratch projects. For one, it can help to make your projects more accessible to people who have difficulty reading. Additionally, adding voice can help to create a more immersive experience for users.
