Having Voice Assistant listen on 2 languages

Sir just got my first M5Stack Echo after trying out a fire tablet as voice Assistant. The tablet version was working good but not needed in every place where I want to use a voice assistant.

The tablet version with Stream assist could listen for different wake words and then use different pipelines. So I could have a wake word to use for German language and another wake word to use Bulgarian language.

The M5 Stack Echo with esphome is only able to configure for 1 language pipeline, is there any way to use 2 languages with 1 M5 Stack Echo?

I plan the echo just for testing and want later to build my own voice assistant but that would have the same limitations.
