Gemini 3.5 Live Translate: Can it support a 4-hour meeting and text-only translation output?

I’m currently testing Gemini 3.5 Live Translate in Google AI Studio for real-time translation during long meetings.

My use case is a meeting that lasts around 4 hours. The speaker will speak in English, and I need Gemini to translate the speech into another target language continuously throughout the whole meeting.

Could you please help clarify the following points?

  1. Is it feasible to use Gemini 3.5 Live Translate continuously for a 4-hour meeting in Google AI Studio?
  2. Are there any session duration limits, token limits, rate limits, or context-window limitations that could interrupt the translation during a long meeting?
  3. I’m using a Google AI Pro account. Does this plan provide higher limits for this Live Translate use case in Google AI Studio, or are the limits still based on the underlying project/model quota?
  4. For my use case, I only need the translated text/transcript to be displayed. I do not need the translated voice/audio output. I already turned off “Echo Target Language”, but the translated voice is still being played back. Could you please confirm whether this is expected behavior, a limitation of the current Google AI Studio UI, or a bug?

This is important for us because we would like to use Live Translate for long internal meetings, but we need to confirm whether it can run reliably for approximately 4 hours and whether audio output can be fully disabled.

Thank you in advance for your support.
