However, Scratch does have a few blocks related to sound:
* Play sound: This allows you to play pre-recorded sounds that you upload into your project. These can be any sound files you find online or create yourself.
* Record sound: This block lets you record a sound directly into your project, but it's not a speech recognition tool.
So, Scratch itself doesn't have a fixed number of "speech sounds" because it relies on external sound files.
If you want your Scratch project to interact with speech, you would need to use:
* Third-party services: There are online speech recognition APIs (like Google Cloud Speech-to-Text) that you could use to integrate into your Scratch project, but this would require some advanced coding and potentially a paid subscription.
* Custom-built solutions: If you are very comfortable with programming, you could create a custom solution by combining Scratch with a programming language like Python, which has more robust speech recognition libraries.
Let me know if you have any other questions about Scratch or sound!
