[D] What are some MNIST/CIFAR level tasks in NLP and Speech Peocessing ?

Hi,

I'm am from the computer vision domain and working on optimisers. I am currently trying it on different **toy** settings to understand it's pros and cons in practice.

What are the mnist/cifar equivalent tasks/datasets for NLP and Speech (maybe, still used in few papers)? A big help if you could direct me to a repo.
