will speak, will talk
Je vous en parlerai plus tard.
I'll tell you about it later.
Je ne vous parlerai plus jamais de mon gendre.
I will never speak to you about my son-in-law again.
I will speak.
Je n'ai parlé de toi à personne et n'en parlerai jamais.
I haven’t told anyone about you, and I never will.
— Souvenirs de Marnie (2014)
Je suis occupé, je vous parlerai plus tard.
I am busy; I will speak to you later.
— Piège de cristal (1988)
Je ne lui parlerai plus jamais.
I will never speak to him again.
