How to generate more MP3 files at the same time in Amazon Polly using Python code?

[makiwara]

Hi!

The programming language of Amazon Polly (TTS) is Python. However, I'm not very familiar with it yet.

I have a list with words and want Amazon Polly to pronounce them and save every word as a new mp3 file. (name could be the word's name)

My list is like:

"
apple
banana
peach
orange
...
"

On the following website there is a code provided by Amazon which result is more mp3 file so seems promising: (I inserted it at the end of my post)
https://aws.amazon.com/blogs/machine-lea...on-script/

My question is, how can I modify that code, so I can use it to generate the pronouncation for each word as a new mp3 file?

Thank you for your help! It means to me a lot!

Have a very nice day!
