Abbreviations with "'s" are not pronunced properly

[Ananya21162]

Using any of the English voices, abbreviations followed by "'s" such as IBM's or MIT's are read as though the 's is not there.
To clarify, "IBM's mainframes" is read as "IBM mainframes". This only occurs if the abbreviation is in uppercase.

Phonemizer version
phonemizer-3.3.0

System
MacOS
Python 3.8.18

To reproduce
Please try with this nput to phonemizer: This repo has been authored by MIT's professor in the field of Machine learning.

This bug was reported in eapeak-ng and was fixed in their latest version. I am not sure why phonemizer is not using the latest epseak-ng and is there a plan to upgrade it?

Hello @Ananya21162 .

The phonemizer uses the version of Espeak that is provided by Brew (1.48). If you want a more recent version, you have to compile it from source. I don't know if you can use espeak-ng on a macos setup (@mmmaat can probably answer that).
