Visit Website ↗Kalem is an AI voice agent platform built to go live in about ten minutes, letting businesses deploy phone assistants that hold natural 24/7 conversations. Through direct speech-to-speech processing it keeps end-to-end response time under roughly 320ms, close to human pace, and supports switching languages mid-call.
It uses a BYOC model — bring your own OpenAI Realtime, Google Gemini Live or xAI Grok voice engine and SIP telephony — and integrates with CRMs, Zapier, Make, n8n and WhatsApp. Voices, tone, accents and system instructions are customizable. It offers 100 free minutes, then usage-based pricing (from $0.04/min on the Kalem engine). It suits developers and teams who want low latency and control over model and telephony.
