Summary
Highlights
The video introduces the speech recognition or speech-to-text extension for Scratch, noting that it was developed for Scratch 3 but not released officially. It aims to show how to use this feature.
To use the extension, viewers need to click a link in the description to open a special Scratch GUI created by machinelearningforkids.co.uk. This GUI offers several new and cool extensions.
Users must click on the 'Speech to Text' extension within the custom GUI. This extension is exclusively for Google Chrome. Once clicked, it provides three blocks: 'listen and wait to get the input', a 'head block', and a variable to display the result.
The video demonstrates a simple test: when the green flag is clicked, the program asks for microphone permission. After granting it, the 'listen and wait' block will convert spoken words to text, displaying them in a variable. An example demonstrates speaking 'youtube' and seeing it appear as text.
A basic program is created to illustrate the blocks in action. A sprite changes costume based on recognized speech, such as 'dog' or 'cat', showing the speech recognition working effectively.
The video highlights other experimental extensions available in the custom GUI, including AI extensions, a bad bird detector, and integrations for hardware like Arduino and Raspberry Pi. It's crucial to note that projects using these unofficial extensions must be saved locally and can only be opened and used within this specific Scratch GUI; they will not work correctly in the normal Scratch editor.
