meanwhile elevenlabs also added some context to this issue
" Hi Markus,
Thank you for reaching out, I will be glad to look into this further for you.
This issue may likely be occurring when using extreme values for the ‘Stability’ and ‘Similarity’ setting parameters.
Keeping the ‘Stability’ value at 50% and the ‘Similarity’ value at 75% will provide the most consistent speech cadence.
If the issue persists, we also suggest keeping the ‘Style Exaggeration’ value at 0% as this feature can also cause inconsistencies.
Please let us know if you experience any further trouble after changing these setting parameters and we will be glad to look into this further for you.

but to really challenge this problem we need to iterate with different parameteric settings, which (at the moment) is not possible for us (only with help of your team). So a direct access to set the voice parameters would be highly appritiated! Maybe even a dynamic setting based on each voice query … so when talking to a LLM we would also want to sent voice parameters - so for long answers we can set different settings than for short answers.
I m out of office now for some days.
