In the realm of voice-enabled platforms, regulatory compliance is essential, particularly for speech-to-text (STT) APIs, which play a crucial role in managing sensitive data. As these platforms scale, selecting STT API providers with the appropriate compliance certifications becomes vital, aligning with industry-specific regulations such as GDPR, HIPAA, SOC 2, and ISO 27001. Important security measures for STT APIs include end-to-end encryption, role-based access control (RBAC), zero data retention policies, and transport layer security (TLS), all of which help protect data throughout its lifecycle. The shared responsibility model highlights that both STT providers and their clients must ensure data security and compliance, with clients managing data flows and access within their own systems. Gladia, as an example, emphasizes compliance by adhering to key standards and offering customizable data handling options, ensuring that sensitive voice data is processed securely and confidentially. For businesses, understanding and selecting relevant compliance standards is paramount to building trustworthy, scalable, and legally compliant voice-enabled products.
