Dictation and Emoji not working

Question

I am using OS X El Captain 10.11.6 (French edition).

For unknown reason, the function Start Dictation (Démarrer la dictée) et Emojis and Symbols (Emoji et Symboles) don't work anymore.

I followed the recommandation in this question: Dictation just stopped working. But, nothing works.

I have just updated to 10.11.6. But, it's not better.

What can I do? How to reset the settings?

NOTE:

• The microphone work (the bars are moving in de Preferences panel).
• When I choose Start Dictation (or fn fn) nothing appends (no microphone picture).
• When I choose Emojis and Symbols nothing appends too.

Answer 1

I encountered this problem, it was fixed in a later macOS update.
