Allow slower playback other than 0.5 or 1.0

[evandrocoan]

The default slower audio only allows 1.0, but it is not enough because the default slow speed is still too fast for some languages.

It would be a line to allow slower speeds other than 0.5 and 1.0, such as 0.1 and 0.5.

I hope to change this line from 1.0 : 0.5 to 0.5 : 0.1 will be enough: https://github.com/blmage/duolingo-tts-controls/blob/0cabed3db0425c3eeaa84d63ce884cb4aca027ac/src/tts.js#L40-L43

I could not test it because I could not build the extension:

I managed to edit the extension minified code, changing Yo=e=>Za(Ua,Da===e?1:.5) to Yo=e=>.1 inside ui.js. However, the user interface only allows up to 0.5 as the minimum. But 0.5 works fine for the slower audio, as the original audio is already slower.

Thanks for the suggestion! This should be available in version 2.7.0 soon.

I could not test it because I could not build the extension:

This is because the extension uses FontAwesome Pro icons, and installing the corresponding package requires a private token (if needed at some point, I may consider solutions to work around this limitation).

However, the user interface only allows up to 0.5 as the minimum.

This is a hard limit from the Howler.js library used by Duolingo, which does not allow rate values below 0.5.

Thanks for the fast response and for adding it to the stable version. I opened a feature request on Howler.js to allow values below 0.5 to the slider. Let's wait and see what they think about it.
