Where can I find a collection of samples of Mandarin spoken words, annotated with pinyin and tones? I recently built the following app that lets you listen to a Chinese word and asks tests your tone hearing ability:

https://tones.strokes.ovh/

I'd like to extend it, but in order to get there I need a collection of Chinese sound samples, annotated with pinyin and tones - and ideally, also Chinese characters related to the sample.

Where could I find such a collection?
Some websites or apps you may need:

IOS app, not test.
Hope it's helpful
