Charles H. Spurgeon on Psalms 114:1

A people of strange tongue. Mant translates this "tyrant land, "and has the following note: The Hebrew word here rendered "tyrant, "has been supposed to signify "barbarous"; that is, "using a barbarous or foreign language or pronunciation." But, says Parkhurst, the word seems rather to refer to the "violence" of the Egyptians towards the Israelites, or "the barbarity of their behaviour, "which was more to the Psalmist's purpose than "the barbarity of their language"; even supposing the reality of the latter in the time of Moses. The epithet "barbarous" would leave the same ambiguity as Parkhurst supposes to belong to the text. Bishop Horsley renders "a tyrannical people."
