Voice AI pricing per minute in 2026 across the platforms US, UK and Indian buyers actually evaluate — Vapi, Retell, Synthflow, Bland AI, ElevenLabs Conversational AI, Twilio Voice AI, AWS Connect, Deepgram Voice Agent and Caller Digital. Published rates, what they actually include, what gets billed separately, and the realistic fully-loaded per-minute cost on a production deployment.
Last updated: Q2 2026. Headline rates rounded to a useful precision; specific deployment quotes vary with AHT, languages, concurrency and CRM integration depth.
All rates below are headline 2026 published pricing or production-deployment estimates. Per-minute USD reflects US deployment; per-minute INR reflects India deployment. Where a vendor's quoted price excludes telephony, STT, LLM or TTS, the “Notes” column says what the fully-loaded cost looks like.
| Vendor | Category | Per-min USD | Per-min INR | Notes |
|---|---|---|---|---|
| Caller Digital | Voice AI platform (India-headquartered, global delivery) | $0.05–$0.09 | ₹3.40–₹6.60 | End-to-end per-call cost including telephony, STT, LLM, TTS, integration and supervision. Hindi + 13 Indian languages, English (US/UK), Spanish. Volume contracts below ₹3.40/min. |
| Vapi | AI-native voice platform (US, developer-led) | $0.05–$0.13 | ₹4.20–₹10.90 | Self-serve, modular. Quoted price is Vapi platform fee only — telephony (Twilio/Telnyx), STT (Deepgram), LLM (OpenAI/Anthropic) and TTS (ElevenLabs/Cartesia) are billed separately. Fully-loaded per-minute is $0.13–$0.32. |
| Retell AI | AI-native voice platform (US, developer-led) | $0.07–$0.31 | ₹5.90–₹26.00 | Self-serve tiered pricing. Includes STT, LLM, TTS, telephony in a bundled per-minute rate. Voice quality tier (ElevenLabs Turbo vs Standard) materially changes the rate. |
| Synthflow | AI-native voice platform (US, no-code) | $0.08–$0.15 | ₹6.70–₹12.60 | Subscription + per-minute on top. Starter ~$29/mo + $0.13/min; scale tiers reduce per-minute. ElevenLabs voice tier extra. |
| Bland AI | AI-native voice platform (US, developer-led) | $0.09 | ₹7.50 | Flat $0.09/min advertised for the standard pipeline. Custom voices, enterprise volume and higher-tier models negotiated. Telephony and number leases on top in many configurations. |
| ElevenLabs Conversational AI | TTS-native platform (US/UK), conversational layer | $0.07–$0.30 | ₹5.90–₹25.20 | Pricing tracks ElevenLabs voice tier. Turbo and Flash voices at lower band; Multilingual v2 and premium voices at upper band. Excludes telephony and LLM call costs. |
| Twilio Voice AI | Telephony infrastructure + AI assistants | $0.01–$0.04 (telephony) + AI add-ons | ₹0.90–₹3.40 (telephony) + add-ons | Telephony itself is the cheapest component. Twilio's AI Assistants and Voice Intelligence add separately metered usage. Build-on-Twilio total per-minute typically $0.18–$0.45 fully-loaded. |
| AWS Connect + Lex/Bedrock | Cloud contact centre + AWS AI services | $0.018 (Connect) + Lex/Bedrock usage | ₹1.50 + AI | Connect is per-minute infrastructure. Lex bots and Bedrock LLM calls billed separately. Real fully-loaded $0.10–$0.28 per minute on production conversational AI deployments. |
| Deepgram Voice Agent | STT-native, voice agent API | $0.0425–$0.08 | ₹3.60–₹6.70 | Bundled per-minute for STT + agent orchestration; LLM and TTS billed separately. Strongest in low-latency US English transcription. |
INR rates assume USD/INR ≈ 84. Specific deployments quote in local currency on contract. India deployments delivered by Caller Digital include local PSTN, Indian-language STT/TTS and DPDP/RBI/IRDAI compliance posture inside the per-minute rate.
A ₹4.80 (≈ $0.07) per-minute voice AI call breaks down across six infrastructure layers. Understanding the stack is what separates a fair price from a marked-up one.
| Layer | Cost / min (INR) | Share | Typical providers |
|---|---|---|---|
| Telephony (SIP / number) | ₹0.90–₹1.40 | 20–25% | Plivo / Exotel / Twilio India |
| STT (speech-to-text) | ₹0.40–₹0.80 | 10–15% | Deepgram Nova-3 / Sarvam / AssemblyAI |
| LLM (with prompt caching) | ₹0.30–₹1.20 | 10–18% | GPT-4o-mini / Claude Haiku 4.5 |
| TTS (text-to-speech) | ₹0.80–₹1.60 | 20–25% | ElevenLabs / Cartesia / Sarvam TTS |
| Integration + platform | ₹0.80–₹1.10 | 15–20% | CRM writes, analytics, orchestration |
| Supervision (1:12k calls/day) | ₹0.20–₹0.50 | 5–8% | Human QA on AI calls |
Quoted rates rarely tell the whole story. The four questions to ask before accepting any per-minute number.
Some platforms (Caller Digital, Retell, Bland) quote a bundled rate that covers all four layers. Others (Vapi, Synthflow, ElevenLabs) quote platform-only and bill the underlying providers separately. A $0.05 platform rate can be $0.18 fully loaded once layers are added.
ElevenLabs Conversational AI and platforms that route through ElevenLabs vary 3–5× in per-minute cost based on voice tier. A demo using Multilingual v2 sounds great; that same deployment running 3 million calls a month at premium tier costs 3× more than the same calls on Turbo.
Enterprise platforms typically reduce per-minute cost 25–55% at 250k+ minutes monthly. Some platforms add concurrency surcharges (over 50–100 concurrent calls) that materially change unit economics for peak-hour outbound campaigns.
LLM costs are falling 30–50% annually. A 12-month contract locked at today's GPT-4o-mini rate denies the buyer that downside. The right contract structure is a per-minute floor with a quarterly true-up against published LLM rates — protecting both parties.
Voice AI pricing questions buyers ask most in 2026.
Caller Digital lands at ₹3.40–₹6.60 ($0.05–$0.09) per minute fully loaded for Indian deployments — the lowest end-to-end cost in the table. Bland AI's $0.09/min flat is the lowest US platform price excluding telephony and number leases. Twilio Voice itself is cheaper at $0.01–$0.04/min, but that is pure telephony — adding voice AI on top brings the fully-loaded cost to $0.18–$0.45/min. Cheapest platform is not always cheapest deployment; the right comparison is total cost per recovered or converted call, not headline per-minute rate.
Vapi's platform fee is $0.05–$0.13 per minute depending on plan tier. That is platform orchestration only — Vapi does not include telephony, STT, LLM or TTS in its quoted rate. Realistic fully-loaded cost on a typical Vapi deployment is $0.13–$0.32 per minute: Vapi $0.05–$0.13 + Twilio/Telnyx telephony $0.013–$0.04 + Deepgram STT $0.0043/min + OpenAI/Anthropic LLM $0.02–$0.06/min + ElevenLabs/Cartesia TTS $0.05–$0.10/min. Volume contracts reduce platform fee but not the underlying provider costs.
ElevenLabs Conversational AI is tiered by voice model. Turbo and Flash voices land at $0.07–$0.12 per minute on the per-minute meter for the official 2026 published pricing. Multilingual v2 and premium voice tiers are $0.15–$0.30 per minute. The quoted rate excludes telephony, LLM call costs and any custom integration. Production deployments using ElevenLabs as the TTS layer (rather than as the full agent) typically pay $0.05–$0.10/min for the TTS portion only, billed inside a broader voice AI platform.
Retell AI's per-minute pricing is tiered from $0.07 (Starter, Turbo voices) to $0.31 (Production, premium voices with high concurrency). The rate is bundled — telephony, STT, LLM and TTS are included in the platform meter. Custom voices, BYO-model and high-concurrency tiers move the rate up. Most production deployments land at $0.13–$0.22 per minute on real call volume.
Twilio Voice's PSTN per-minute is $0.0085–$0.014 outbound US, $0.0085 inbound US, plus number lease at $1.15/month per local number. Twilio AI Assistants and Voice Intelligence add separately metered usage, typically $0.10–$0.20 per AI assistant minute. Build-on-Twilio total fully-loaded per-minute for a voice AI workflow runs $0.18–$0.45 — comparable to AI-native platforms once everything is layered. The buyer's choice is rarely 'cheaper or more expensive' — it is 'who orchestrates the AI conversation layer and at what total deployment cost.'
Because voice AI is not telephony — it replaces a human agent's conversational labour. Raw telephony moves the audio. Voice AI does the conversation: ASR, LLM reasoning, TTS, tool invocation, conversation graph, outcome capture, compliance audit. The fair unit-economics comparison is voice AI cost per call vs human-agent cost per call (₹9.20–₹14.50 per call on an Indian Tier-1 collections floor, $15–$30 per call on a US contact-centre seat). Voice AI lands at ₹3.40–₹6.60 per call in India and $5–$15 per call in the US — 40–70% cheaper than the human equivalent, not more expensive.
Three numbers determine the per-minute cost: average handle time (AHT), languages required, and CRM/system integration depth. A 90-second AHT Hindi collections call sits at ₹3.40–₹5.20/min. A 180-second English-Spanish US customer-support call sits at $0.12–$0.22/min. A 240-second multilingual outbound qualifying call with 4 CRM tool calls sits at the upper end. Ask the vendor for a quote on your specific workload — not their headline rate. Caller Digital's pricing model is published at /voice-ai-pricing-india with volume-tier breaks.
Headline per-minute rates are starting points. A 200,000 call/month workload with Hindi + 4 regional languages and 5 CRM tool calls per call has a specific number. Tell us the AHT, language mix and integration depth — we will quote in 24 hours.
