It is the same way His disciples did not speak in ministry when Jesus was on earth.
Matthew 10:19 But when they deliver you up, take no thought how or what ye shall speak: for it shall be given you in that same hour what ye shall speak. 20 For it is not ye that speak, but the Spirit of your Father which speaketh in you.
So they were speaking but the words were coming from the Father through the Holy Spirit.
See how it is the same for the Holy Spirit when He speaks? As it was not really His disciples that were speaking, the same goes for the Holy Spirit speaking the words through them because the words came from the Father.
Now that Jesus has ascended into Heaven, the Holy Spirit does not speak from Himself, but speaks the words from Christ. This truth is found in all Bible versions in John 16:13
John 16:13 Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come. KJV
John 16:13 When the Spirit of truth comes, he will guide you into all the truth, for he will not speak on his own authority, but whatever he hears he will speak, and he will declare to you the things that are to come. ESV
John 16:13 But when he, the Spirit of truth, comes, he will guide you into all the truth. He will not speak on his own; he will speak only what he hears, and he will tell you what is yet to come. NIV
John 16:13 Howbeit when he, the Spirit of truth, is come, he shall guide you into all the truth: for he shall not speak from himself; but what things soever he shall hear, these shall he speak: and he shall declare unto you the things that are to come. ASV
John 16:13 But when He, the Spirit of truth, comes, He will guide you into all the truth; for He will not speak on His own initiative, but whatever He hears, He will speak; and He will disclose to you what is to come. NASB 1995
So the Holy Spirit will not speak of Himself, nor on His own authority, nor on His own, nor speak from Himself, nor speak on His own initiative, but speaks only what He hears as He relays the words of Christ to us in serving as the Spirit of Christ.
