Frequently Asked Questions
How do I compare STT provider costs?
Enter each provider's current rate and use the same monthly minutes for every candidate. Review current billing and language coverage documentation, including model, region, minimum-charge, and rounding rules. There is no durable cheapest provider for every workload.
How accurate are these STT APIs?
Accuracy varies with language, accent, microphone, noise, vocabulary, and model changes. Compare every candidate with the same representative recordings, then confirm current language coverage and streaming features in the provider documentation.
Can I switch providers without losing my settings?
Yes — OpenTypeless stores each provider's API key and settings independently. Switch providers with one click from the settings panel.
