I’m not sure what you mean by “oral” here.

In Jainism, “oral” could refer to:

• Oral tradition (how Jain teachings were memorized and passed down)
• Oral vows (promises taken by speaking them)
• Oral practices like reciting sutras, stavans, mantras

Please tell me a bit more, for example:

• “oral teachings in Jainism”
• “oral sex in Jainism”
• “oral recitation of Navkar Mantra”

Then I can answer properly, in a simple and clear way.
