Christians, I want to talk to Jesus Christ. How do I know it's Him talking instead of me talking to myself?

Hyacinth,God's word is spoken in the Holy Bible, [2nd Timothy 3:16-17] " All scripture is God breathed and is useful in teaching, rebuking, correcting and training in righteousness, so the man of God is thoroughly equipped for every good work." You can study scripture, it is Christ talking to you and giving you instruction, Make Jesus the Lord of your life, develop a personal relationship with him by "praying continually, giving thanks in all circumstances, this is God's will for you in Christ Jesus." [1st Thessalonians 5:17-18]

Christ did say that His sheep know His voice. You need to become His, follow Him and live His way of life and love to be able to discern His voice.

His word is in print, go read it, it will not be you talking to yourself
