Hi @Ahron268938
Welcome. Good to have you with us. 
Cool ideas. Lots to do but it’s all manageable.
Tools
This tech chain seems similar to this popular guide by a Tim who I think used to work at Core electronics. Maybe have a look at it for inspiration. 
This github repository also uses a similar tech stack.
This repository is NOT under a open source license which means you cannot clone it and use the code freely. However, it is there for you to read and learn from :).
If you do learn anything from this GitHub repository don’t forget to reference HimanchalChandra (author) as a source.
Audio
I’m going to assume your working in python here based on the rest of your tool-chain.
There are two paths here and it depends on your project requirements.
- Do you want your final project to be able to identify ANY OBJECT in general? This would mean you need some kind of “text to speech engine.”
- Do you want your final project to be able to identify a pre-planned list of object. The way I would accomplish this is asking my most American friend record samples of him/her reading aloud from your list. Then playing back those recordings on demand with some audio library.
Which one of the above sounds more like the direction you want to head?
