HI.
If you will not be tolerated by someone unless you SPEAK everyday, I think second one is correct.
In Japanese, "話かない" is wrong because conjugation of a verb "hanasu" are "話さない","話します","話す","話せ"," 話そう".
If you will not be tolerated by someone unless you WRITE everyday, not "話" but "書".
conjugation of a verb "kaku" are "書かない","書きます","書く","書け"," 書こう".
