We’ve simplified and accelerated speech recognition for AI Assistants by enabling native Azure Speech-to-Text (STT) support, no customer API key required.
The “azure/fast” configuration integrates Azure STT directly into the Telnyx AI stack, providing lightning-fast transcription with sub-200ms latency and exceptional accuracy across a wide range of languages and dialects. Azure’s multilingual support makes it especially powerful for global users. For example, our tests show that Azure provides the highest-quality Arabic transcription currently available within the Telnyx platform.
This update removes integration friction and accelerates real-time voice AI performance. By eliminating the need for API key management, developers can deploy enterprise-grade, multilingual voice AI assistants faster and more securely. Azure’s advanced transcription models also enhance accuracy in complex or accented speech, ensuring smoother, more natural interactions.
This improvement reinforces Telnyx’s position as the full-stack conversational AI platform, delivering performance, flexibility, and global language reach from a single infrastructure.
