What you get

Custom Voice Stack Assembly (Self-Rolled)

For sophisticated buyers who don't want a framework like Pipecat or LiveKit — they want individual components stitched together for maximum control. Voice as a core product capability, not a feature bought from a vendor. We pick the right STT (Whisper / Sarvam / AI4Bharat / custom), LLM (Llama / Mistral / GPT-4 via Ollama / Anthropic / hybrid), TTS (Coqui / ElevenLabs / AI4Bharat / custom), telephony layer (Twilio / Plivo / Exotel / custom SIP), and orchestration approach (state machine, LLM-driven, or hybrid). Then we build the whole assembly in your repo, no framework dependency. Highest complexity, longest timeline, deepest customization in the catalog.

Scope & Responsibilities

What's in scope (and what isn't)

Honest framing of the engagement. Self-hosted deployments give you control — and the ongoing infra bills come with that control.

Included in the fixed fee for this package.

Architecture design and infrastructure provisioning runbook

You own

What stays on your side

Costs we don't pay or pass through. You retain accounts and pay the bills directly.

Cloud infrastructure account (AWS / GCP / Azure / your own)
LLM API account and bills (OpenAI / Anthropic / Gemini / etc.)
STT API account and bills (Deepgram / Sarvam / Azure / etc.)
TTS API account and bills (ElevenLabs / Cartesia / Sarvam / etc.)
Telephony account and bills (Twilio / Plivo / Exotel / etc.)
Ongoing infrastructure operations (covered if you add the maintenance retainer)

Want us to take infra and ops off your plate too? Add an OSS Voice Maintenance Retainer (Rs 29,999 - Rs 99,999/month depending on tier). Or move to the Edesy managed platform where the per-minute rate includes all the infra and ops by default.
