Hi.Is it possible to activate audios in Spanish?
Perhaps set your Operating system's language to Espanol?
The strings used (for text to speech) are in English. Setting the system TTS engine to Spanish will only "speak" the English strings using Spanish phonetics. The whole of QGC as well as the autopilot would need to be localized (translated) for this to work properly.
