Very neat new TTS engine, works in a wide variety of languages (e.g. English UK/US, German, Afrikaans) and with different inflections and voices.

Also works locally and (once the generator is downloaded the first time) super fast (on my pc takes around 10 seconds for generating a minute of speech in German). Since you will usually have shorter speech snippets will work even faster.

Can be used in client/server setup, through the local cli or as part of the mycroft engine. Neat!

Query the Openstreetmap database through natural language queries. Part of a master thesis currently, but already fun to play around with.

Pre-made models trained for natural language processing -- can summarize, generate, identify, answer questions, etc.

date-time parser for go. Similar to dateparse for python, just for Go - and I'm not sure if it supports as many natural formats, or languages.

Simple date-time parser, with nice unix-y philosophy.

Demo shows how it can be integrated into e.g. vim workflow for switching between different representations of dates,
and moving dates up, creating diaries with hundreds of entries, etc.

Written in python and intended for web scraping.

What's really nice is that is supports a lot of languages (english, french, spanish, russian, german, etc) without any need for switching in code.
