ANDROID Where can I find the old HiFi voices for HERE Maps

Hello,

I am looking for an archive of the HiFi voices for HERE Maps - Android.
I am aware that the newer versions of HERE Maps no longer support HiFi voices (for TTS function and street names). HERE Maps once supported HiFi voices in the past.

My plan is to download an old BETA.apk (from when it still had HiFi voices working). Then I will stop the app from automatically updating to the new version. In this way I can keep the HiFi function.

However, I still need to find the HiFi voices. Can someone please tell me where to find them. If someone has the English and Spanish HiFi voices, can you please share them with me. Also, please tell me where I need to copy/paste the HiFi voices (what folders).

I want to try to have TTS function and install it on my car - Android Head Unit (KitKat 4.4.4).
Also, will the new maps work with the old version, or do I need to find old maps as well?

Any help will be great.

Thanks,
