MITADS - new corpora to import about deepspeech-italian-model

[Mte90]

Thanks I was thinking to do a ticket with those :-D

I was thinking to add also the new speech of the president.

About Trilussa we need to check, as Poet he was wiring a lot of stuff in roman dialect and for our needs is not suitable.
Anyway we should check for content that is like discussion or wrote in first person, so journalism stuff is perfect.

The file to add those stuff is for wikisource: https://github.com/MozillaItalia/DeepSpeech-Italian-Model/blob/master/MITADS/assets/wikisource_books.txt

In the italian wikimedia community they are discussing to move that new stuff in the website so we have to wait a bit.

• 34983
• 49231
