However, it's possible "Soua" is a name or a word in a different language.
To figure out the correct pronunciation, you need more context:
* Is it a name? If so, you could try asking the person how to pronounce their name.
* Is it a word in another language? If you know what language it's from, you could search for it online or consult a dictionary.
Without more information, it's impossible to give you a definitive answer.
