Worked example
If the tool says to check the entered values, the multiplier is empty or outside 0.25× to 4×.
Type a number in that range or press a preset button and run it again.
Voices that sound watery, flanged or stuttering usually mean the multiplier is too extreme or the source was heavily compressed. Try 0.85× instead of 0.5×, or start from a WAV or a 256 kbps file rather than a 64 kbps voice memo.
If you expected a deeper or higher voice and nothing changed, that is by design: the tool changes tempo and keeps pitch. It is not a pitch shifter, so use it for pacing, not for disguising a voice or retuning a song.
A long recording that stalls or fails in a phone browser is usually running out of memory, because the whole file is processed locally. Cut the lecture into 10 to 15 minute pieces first, process each at the same multiplier, and join them afterwards.
If a message says the media tools could not be prepared, the browser could not load the processing engine, typically because of a blocked or unstable connection on first use. Reload the page, check the network, and try again. In every case, keep the original file untouched, so that you can always start again from a clean source, whatever the cause.

What should I listen for in the exported audio?
