Selected voice is different than the received voice in live API

[awnyshaheen]

Hi,
we use the mutlimodal live API with latest genai sdk v2.4.0

Environment details:

Programming Lanugage: python
OS: linux
Language runtime version: 3.12
Package version: v2.4
LLM Model: vertex/gemini-live-2.5-flash-native-audio
Voice: Achird
we noticed recently that every 10-12 sessions the model decides to pick different voice internally even though we selected specific voice

How to reproduce:
use same sdk, same model, same voice and initiate many sessions then you will notice suddenly it talks with different voice

Thanks
