What is the best format for audiobook

I have an old smartphone (nexus 5, andriod 6) that i want to convert my audiobook that i owned to the lowest size possible so i can put it on that particular phone (only 16GB of storage) and still be audible. 


Please excuse if that is a noob question.

I believe this is the top 3 for speech/audiobooks currently:
1. xHE-AAC
2. Opus
3. HE-AAC v2

xHE-AAC is quite new and not many apps can open it. It's also the hardest to decode (=eats more battery). Comparing the other two, on my Android phone in Foobar2000 at least, Opus decodes faster than HE-AAC v2 (on my PC it's the opposite).
Based on this, Opus seems like the best choice, unless you can find a way to play back xHE-AAC and don't mind the higher CPU usage.

There are some even more exotic speech-centric formats out there--like a couple developed by MS and Google and also LC3, part of the new BT spec--but I don't know if there are any encoders available to the public, so I doubt that they can be of any use for this purpose.

Which players support it? You have to go that way, not finding the perfect codec and then have no playback support.

Do you really want to listen to a robot/synthesizer speaking to you for hours? At 32 kbit/s and 8 hours, you're looking at 110 MB of disk space. That is well within the budget.
