Would it be possible to make the AI voices speak year numbers at the end of sentences? When they’re in the middle of the sentence or just before a comma, they’re spoken out just fine. Just a few examples
“En torno al 1100 Tiwanaku desapareció…” works fine
“El 17 de agosto de 1825,…” works fine
“…apenas 30 años de edad Antonio José de Sucre el 29 de diciembre de 1825.” 1825 is not said by the AI voice
