Deepgram vs Google vs Azure: Which Cloud Provider Wins at STT?
Blog post from Deepgram
The article provides a comprehensive comparison of Deepgram, Google Cloud, and Azure as speech-to-text (STT) providers, focusing on total cost of ownership (TCO), latency, compliance, and deployment flexibility. It emphasizes that choosing the right STT provider largely depends on existing cloud ecosystems, streaming architecture, and compliance requirements. Deepgram is highlighted for its flexible deployment options and simple pricing model, while Azure is noted for its strong government compliance capabilities. Google Cloud offers integration advantages for users already within its ecosystem but has limitations like geographic constraints for its Chirp 3 model. The article advises conducting independent tests on accuracy and latency using real audio data and considering all supporting services' costs. It also mentions that all three providers offer HIPAA compliance, but only Azure has explicit FedRAMP authorization for AI services. The guide stresses the importance of evaluating these providers based on actual production needs rather than relying on vendor marketing claims.
