Guava is a voice agent API platform for building and deploying production-grade voice interfaces. It provides a comprehensive toolkit for developers to create capable voice applications with low latency, multilingual support, and deterministic behavior. The platform integrates proprietary ASR, TTS, and language models, and offers a Python SDK with structured task checklists that replace open-ended prompts, ensuring predictable call flows. Guava supports agentic tenacity—cross-session context, re-contact strategies, and multi-channel handoffs—making it suitable for real-world environments like contact centers, hospitals, and financial services. It also features production telephony with inbound/outbound calls, SMS, call transfer, and DTMF, eliminating the need for third-party glue code. Guava is designed for enterprise compliance, with SOC 2, PCI DSS, and HITRUST certifications, and can be deployed in the cloud, on-premises, at the edge, or embedded.
