What is Rev AI?
Rev AI is a speech-to-text API from the Rev family, built for developers who need to convert audio into text. It offers machine transcription of pre-recorded files as well as real-time streaming transcription, with proper grammar, punctuation, and formatting across 57+ languages. The company says its proprietary models are trained on a subset of a library of over 7M hours of human-verified speech.
Beyond transcription, the API includes word-level forced alignment for precise timestamps, language identification, sentiment analysis, topic extraction, summarization, and translation. Developers can integrate it through the API and SDKs, deploy in the cloud or on-prem, and use human transcription when higher accuracy is needed. The site also lists HIPAA, SOC II, GDPR, and PCI compliance, and 99.99% uptime.
