When would you choose translated voice over original audio?

TCVoiceAI supports two ways to run a bilingual call. Translated voice replaces both sides' original speech with translated speech. Original audio keeps both real voices live while building bilingual History without spoken translation.

I built both because some calls need immediate spoken translation, while others benefit from keeping natural voices and reviewing the conversation later.

Which mode would you trust first for a customer or team call, and what would make you switch?
