Speed up audio

Is it possible to implement a system to speed up the audio? If we can slow it down, I’m sure we can speed it up. Some audio recordings are quite slow and not at a natural speed.

You can adjust your audio pressing with 1x
press till you find your prefered speed. 1.5x or 2x.

but i like 1.25x it doesnt change pronunciation but like decrease the gaps between the voice.

javascript:(function(){document.querySelector(‘audio’).playbackRate=prompt(‘Audio Speed (0.5-4)’)})()

here is a bookmarklet i use. You can drag and drop to your bookmarks and u can type “0.5-4” (between this numbers) and it will play the audio in the speed you choose. If you want to change another speed just click again and type your speed.
