/min
What's Included
Real-time STT, LLM, and standard TTS
AI orchestration with barge-in, memory, and tool calls
Full media control and real-time API triggers
Voice transport and TTS playback billed transparently at cost
Built-in Agent memory and retrieval (RAG-style grounding)
*Standard TTS is included in the $0.16/min runtime. Premium TTS available for a small additional per-minute cost.
**Voice transport (SIP/PSTN/WebRTC) is billed at standard rates.
***Most customers see an all-in rate of ~$0.163–$0.168/min for standard SIP/PSTN usage with standard TTS.
Platform Comparison
DIY stacks piece together STT, LLM, TTS, and orchestration from multiple vendors, reprocessing audio and context at every step. SignalWire runs it all in one runtime.
Category
SignalWire
DIY Stack (Vapi, Telnyx, LiveKit, etc.)
AI Runtime
One flat rate ($0.16/min for full-stack AI voice).
Multiple vendors: LLM, STT, TTS, logic with each billed separately.
Voice Infra + TTS
Telecom and TTS passed through at cost.
Separate contracts and fees across providers (SIP, WebRTC, TTS).
Setup Complexity
No integrations required, hosted SDK and APIs.
Orchestrate 4–6 APIs for voice, media, AI, routing, memory and more.
Billing
Single invoice with transparency, bundled pricing.
Fragmented invoices with unpredictable usage costs.
Operations & Scaling
Fully hosted, runs in containers or serverlessly. No infrastructure or token limits.
Dev time to deploy, scale, and monitor usage across APIs. Hidden costs from token spikes.
Price Predictability
Transparent per-minute rate includes media, logic, and AI.
Per-minute cost is unclear; token usage varies by vendor and model.
Context & Memory
Built-in Memory and local RAG included via Datasphere.
Requires custom vector DBs (e.g., Pinecone) and external LM tools to manage memory or context grounding.
Voice Transport
Billed at standard rates, additive to AI runtime.

¹ Based on inbound SIP transport and standard TTS playback (~$0.008/min passthrough). Includes full AI runtime: STT, LLM, orchestration, and media.
² Blended estimate based on public pricing for Deepgram (STT), OpenAI GPT-4o (LLM), ElevenLabs (TTS), Telnyx (SIP), and Vapi (orchestration layer). Assumes average usage across standard 2-minute calls with minimal retries.
Real-world rates often exceed this due to token spikes, retries, or premium voices.

Pricing Notes
Standard TTS is included in the $0.16/min runtime. Premium TTS (ElevenLabs, Rime, etc.) is available for an additional per-character cost.
Voice transport (SIP/PSTN/WebRTC) is billed at standard rates on top of the AI runtime — see breakdown below.
Most customers see an all-in rate of ~$0.163–$0.168/min for standard SIP/PSTN usage with standard TTS.
No token limits, no infrastructure overhead. Flat rate includes LLMs, STT, orchestration, and media logic.
