What Is a Protected Speech-to-Text Workflow Tool?
A protected speech-to-text (STT) workflow tool is a platform designed to convert spoken language into text while adhering to strict security and privacy standards. Unlike standard transcription services, these tools offer features like end-to-end encryption, zero-data-storage policies, on-premise deployment options, and compliance with regulations like HIPAA and SOC 2. They are engineered to handle sensitive information by minimizing data exposure, providing auditable access logs, and often including features like PII redaction. These tools are essential for enterprises in regulated industries that need to process audio data without compromising confidentiality or security.
