A speech displaying system and method can display playing progress by waveform and synchronously display text of a speech file using rolling subtitles when playing the speech file. After the speech file is loaded via a loading module, a sentence unit determining module partitions content of the speech file into a plurality of sentence units to produce a list of sentence units. A subtitle highlighting speed calculating module calculates a speed of highlighting every single letter or character contained in the subtitles in the sentence unit index for a sentence unit. A subtitle rolling module displays content of the list of sentence units. When the speech file is played, the subtitles in the sentence unit index are clearly marked, and every letter or character of the subtitles is highlighted. A waveform displaying module marks positions of sentence pauses and playing progress on an oscillogram for the speech file by lines.
