PickMyCall, built by Roojoom, delivers low-latency customer service with Amazon Nova Sonic
Use case typeVoice automationUpdated Jul 15, 2026
Roojoom upgraded its PickMyCall AI voice agent for SMBs by moving from a speech-to-text-to-speech pipeline to native speech-to-speech. The goal was to reduce latency, improve conversational flow, and support customer service tasks such as inbound call handling, lead capture, appointment scheduling, and call prioritization. Roojoom also used Amazon OpenSearch Service for search, observability, and vector database operations.
