To control the typing speed of a dialogue UI's subtitle text, inspect the Subtitle Text GameObject. The basic Scrolling Dialogue UI prefab uses Unity UI Text, so it has a UnityUITypewriterEffect component. Increase its Characters Per Second:

However, I recommend enabling TextMesh Pro Support. Then replace the Subtitle Text GameObject with a TextMeshProUGUI version, and add a TextMeshProTypewriterEffect:

Also configure Auto Scroll Settings, which I also highlighted above.
Remember to assign it to the Subtitle Panel Info's StandardUISubtitlePanel component:

If you only want to show the NPC's portrait, tick the Subtitle Panel Info GameObject's Only Show NPC Portrait checkbox, and unassign these two fields on the response menu:
