 #### Speech Conversation as an AI Assistant
 
-An enhanced feature of `MiniCPM-o-2.6` is to act as an AI assistant, but only with limited choice of voices. In this mode, `MiniCPM-o-2.6` is **less human-like and more like a voice assistant**. In this mode, the model is more instruction-following. For demo, you are suggested to use `assistant_default_female_voice`, `assistant_male_voice`. Other voices may work but not as stable as the default voices.

+*Please note that, `assistant_female_voice` and `assistant_male_voice` are more stable but sounds like robots, while `assistant_default_female_voice` is more human-alike but not stable, its voice often changes in multiple turns. We suggest you to try stable voices `assistant_female_voice` and `assistant_male_voice`.*
