FAQ
Questions about Google Cloud TTS alternatives
What is the best European alternative to Google Cloud Text-to-Speech?
KugelAudio is a German company building real-time text-to-speech in 39 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.
Can Google Cloud Text-to-Speech keep data in Europe?
Google offers an EU multi-region endpoint (eu-texttospeech.googleapis.com) that keeps data at rest and in use within Europe. The service still runs on Google Cloud. With KugelAudio’s Sovereign Cloud, AWS, Google Cloud and Microsoft Azure are not engaged.
How does pricing compare?
KugelAudio charges per generated minute: €0.035 for kugel-2-turbo and €0.07 for kugel-3. Google bills per character, for example $30 per 1M characters for Chirp 3: HD voices and $4 per 1M for Standard and WaveNet voices.
How fast is KugelAudio?
In our benchmark run, Kugel v3 reached a 91 ms median time to first audio, measured over WebSocket streaming from an EU data centre with connection setup excluded.
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.
