General

Q: Translation isn't accurate — what can I do?

A: A few common culprits:

• Media volume too low: voicepie picks up audio less clearly. Turn it up.
• Noisy environment: Move to a quieter spot, or speak closer to the mic.
• Speaking too fast or talking over each other: Slow down a bit, wait your turn, break long sentences into chunks.
• Accent or unclear pronunciation: Use standard speech where possible, avoid slang, repeat important info if needed.
• Specialized terminology: Use more common words where possible. For critical terms, run them through translation alone first to confirm.
