Burki orchestrates the full voice AI stack — telephony, STT, LLM, and TTS — and lets you swap any provider per assistant. Use BYO keys to pay providers directly at wholesale rates.
Voice AI quality depends on more than one model. A production call touches telephony, streaming audio, speech-to-text, language reasoning, text-to-speech, tools, webhooks, and often a CRM or ticketing system. Burki lets you compose those layers instead of forcing every assistant into a single bundled provider path.
Teams use this flexibility to tune each assistant for a specific business need. A healthcare intake assistant may prioritize compliance, transcript quality, and deterministic routing. An outbound sales assistant may prioritize fast turn-taking, CRM updates, voicemail handling, and low per-minute cost. A support assistant may need reliable knowledge-base access and clean handoffs to a live team.
