As an example, I add a couple of screenshots from Audible that are amazing.
People have asked Audible to improve it a few years ago and they have step by step improved and found a really nice perfect solution.
When we click on the audio speed, another window is opened, and we can select to a 0.05x precision.
That would be wonderful for language learning, so that we can tweak to our preferred speed and save a lot of time. Jumping from one speed to another from those available is not always so easy. Plus, speed choices are not even the same across devices.
iPad and iPhone are the same, it is the same iOS app.
On the webapp there’s no 1.1x and 0.66x is 0.6x.
If they would implement the Audible style would be very useful. Jumping from 1x to 1.25x or 1.5x is not a joke on difficult languages, there is no smooth progression to train gradually.
