Is it among the recommended acts of fasting not to speak excessively?

Preserving the tongue from idle and useless talk is an important religious objective, and this is emphasized during fasting, so it is recommended for the fasting person to guard their tongue from disliked speech. Speaking much in the remembrance of Allah and the like is good and commanded, but that which has no religious benefit is blameworthy. The jurists have stipulated this, citing the Prophet's (peace be upon him) saying: "Whoever believes in Allah and the Last Day, let him speak good or remain silent," and his saying: "From the excellence of a person's Islam is his leaving alone that which does not concern him." Drawing closer to Allah by abandoning permissible desires during fasting is not complete except by abandoning what Allah has forbidden in all circumstances, such as lying, injustice, and aggression. The Prophet (peace be upon him) said: "Whoever does not abandon false speech and acting upon it, Allah has no need for him to abandon his food and drink," and "Fasting is not from food and drink; rather, fasting is from idle talk and obscenity." The Salaf emphasized that true fasting includes the fasting of the hearing, sight, and tongue from lying and forbidden things, and adorning oneself with dignity and tranquility.
