How Vonage Uses CAMARA APIs to Improve Developer Experience

Vonage fully supports open standards like CAMARA to simplify access to network capabilities. Rather than standalone endpoints, we’ve embedded CAMARA APIs directly into our products to give developers more flexibility and a smoother experience. Alvaro Navarro offers real examples of how this approach enhances Vonage APIs.

Man in the Loop vs. LLM in the Loop

Vonage AI is rethinking speech-to-text benchmarking by combining human oversight with automation. The teams use large language models (LLMs) to generate consensus transcriptions from multiple STT outputs — which then enable scalable, unbiased, and context-aware evaluation.Yotam Luz compares this approach with traditional methods and the key insights from our experiments.
