FAQ
Questions about ElevenLabs alternatives
What is the best European alternative to ElevenLabs?
KugelAudio is a German company building real-time text-to-speech in 26 languages, hosted in the EU. The EU Sovereign Cloud option engages only EU companies as subprocessors, and it is included on every plan rather than sold as an enterprise add-on.
How hard is it to switch from ElevenLabs?
KugelAudio exposes an ElevenLabs-compatible subset of the HTTP and WebSocket API. Change the base URL to https://api.kugelaudio.com/11labs, use your KugelAudio API key and voice IDs, and pick an output format. Existing ElevenLabs SDKs and integrations keep working.
Is there an ElevenLabs alternative that avoids the US CLOUD Act?
Yes. KugelAudio is a German GmbH under EU law with its IP in Europe. Under the Sovereign Cloud agreement, AWS, Google Cloud, Microsoft Azure and Lambda are not engaged, so no provider with a US parent processes your data.
How does KugelAudio compare to ElevenLabs on quality and latency?
In a blind A/B test with 339 human evaluations on German samples, KugelAudio ranked first with a 78.0% win rate, ahead of ElevenLabs v3 and Multilingual v2. Kugel v3 reached a 91 ms median time to first audio versus 126 ms for Flash v2.5 and 431 ms for Multilingual v2.
How much audio does voice cloning need?
KugelAudio clones a voice from under one minute of audio. ElevenLabs professional voice cloning documents a minimum of 30 minutes and recommends two to three hours, plus several hours of fine-tuning.
Can I run the models on my own infrastructure?
Yes, within days. The models run in your data centre behind your firewall with the same SDK and API as the hosted service, handling up to 192 concurrent calls per GPU.
