How Gnani.ai Can Connect to Business Systems
Gnani exposes public REST, SSE and WebSocket APIs for STT, TTS and voice-cloning. The documentation assumes integration with telephony infrastructure (telephony bridge, RTP tap or contact-center provider) for PSTN-level inbound/outbound calling; PSTN number provisioning or SIP trunking details were not found in the reviewed official docs.
Telephony-level call handling (SIP trunking, PSTN number provisioning, inbound/outbound dialing) is not documented — integrate using a telephony bridge/RTP tap or a contact-center provider to ingest/emit audio to Gnani’s WebSocket/REST endpoints (see Real-Time Compliance architecture).
APIs use X-API-Key-ID for authentication on every request and header-based configuration for realtime connections (e.g., lang_code, x-sample-rate for STT WebSocket).
Batch STT provides transcript_url pre-signed links for downloading full transcriptions; webhook callbacks are supported for job completion.
Common Gnani.ai Use Cases
Platform messaging and docs reference workflow automation, Agent Builder, and analytics pipelines. The speech-API docs provide the realtime and batch building blocks; full KB/retrieval and function-calling surfaces appear at platform level in adjacent components rather than in the speech-API corpus.
Real-time compliance and quality monitoring (stream audio → WebSocket STT → rule engine → webhook alerts).
Call analytics and LLM-powered post-call analysis using Batch STT outputs.
Interactive voice agents and IVR synthesis using realtime/streaming TTS.
Voice cloning to reproduce speaker characteristics for notifications or personalized outbound messages.
