Spanish phonemizes "á" as "ˈa asɛntwˈaða"

[DrBrule]

Describe the bug
In Spanish, the system phonemizes a lone "á" as "ˈa asɛntwˈaða," (a acentuada) essentially describing the letter rather than transliterating it as a normal speech participle.

Phonemizer version
3.3.0
System
Ubuntu 22.04, python3.10

To reproduce
Phonemize some text with "á" as a standalone word.

Expected behavior
Should phonemize as "a" or something similar.

Additional context
Is this perhaps an issue with espeak? Using es-la and es gives almost the same result, with the word "acentuada" include.
