Frequently Asked Questions
Which STT provider is cheapest?
There is no durable cheapest provider for every workload. Enter the current rates for your candidate routes, include model and regional rules, and compare the result with the latest Groq, AssemblyAI, Deepgram, and other provider billing terms.
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.
