Voice inconsistency - stuttering and filler sounds (aaaa, ehhh, hmmm)?

Hey everyone,

I’m building a customer service agent in Swedish and I’m experiencing some really inconsistent voice quality. Sometimes the agent sounds great and natural, but other times it stutters or makes weird filler sounds like “aaaa”, “ehhh”, “hmmm”, “ja…” mid-sentence.

It’s especially noticeable when:

  • Answering questions about products

  • Reading out phone numbers or addresses

  • Transitioning between topics

My setup:

  • Language: Swedish

  • Voice: [which voice are you using?]

  • Multi-state system with knowledge base

What I’ve tried:

  • Cleaning up my prompts

  • Being more explicit about pronunciation

  • Testing different times of day

Has anyone else experienced this? Is this a known issue with Swedish voices, or am I doing something wrong in my prompts?

Any tips would be super appreciated!

Thanks!
