We compared four major Voice AI platforms on real per-minute cost, free-tier value, and workflow fit. Headline findings: ElevenLabs Agents $0.08/min hosting (flat across all tiers) with premium TTS. Vapi $0.05 platform fee + BYO stack landing at $0.115–$0.42/min real-world. GoHighLevel Voice AI runs inside their CRM, with per-minute rates visible only after login to the billing console. TRTC $0.10/min post-paid — plus ~990 free Conv AI minutes every month, on every plan (Free Trial + post-paid included; AI plan gating removed in 2026), drawn from a unified 10k-minute pool that converts at 10.10× for Conv AI, 20.2× for STT, 16.16× for real-time translation, and 606 free min per 10k TTS characters. The "cheapest" vendor depends entirely on how much you value a recurring free bucket versus the lowest per-minute rate.

Methodology
- Tested on: identical voice-agent workflow (customer service bot, 3-minute average call, GPT-4o mini as the LLM layer, April 2026).
- Compared on: hosting rate, included minutes, overage rate, total all-in cost per call including LLM/TTS/STT.
- Data cut-off: 2026-04-22. All four vendors' public pricing was accessed on this date.
- Disclosure: we build Voice AI products; competitor evaluation is as objective as we can make it. Verify with each vendor directly before procurement.
1. TRTC Conversational AI — $0.10/min post-paid with recurring free minutes
Homepage: trtc.io · Pricing: trtc.io/pricing
Quick specs
- Hosting rate: $0.10/min post-paid
- Free minutes: ~1,000/month, recurring on every plan (from unified 10k free-minute pool)
- Plan gating: None — available on Free Trial, Lite, Standard, Pro, and post-paid
- TTS: Built-in Flash + multilingual
- STT: Built-in basic + advanced
- LLM: BYO (integrate your own provider)
- Burst pricing: not required — post-paid absorbs overage at base rate
Core features
TRTC's voice-agent stack sits inside the same platform that handles its RTC traffic, so the same 10,000-minute free bucket covers RTC minutes, Conversational AI, TTS, STT, and real-time translation. AI services are no longer plan-gated in 2026 — they're available on every RTC engine version, including Free Trial and post-paid. The conversion ratios are documented publicly:
- 1 min Conv AI = 10.10 free minutes → ~990 min Conv AI per month for free (post-paid rate $0.01/min after the pool)
- 1 min STT (basic or advanced) = 20.2 free minutes → ~495 STT minutes ($0.02/min after)
- 1 min real-time translation = 16.16 free minutes → ~619 translation minutes ($0.016/min after)
- 10,000 chars TTS (Flash or multilingual) = 606 free minutes → ~165k characters ($0.6 / 10k chars after)
Once the free bucket is exhausted, usage draws from your monthly plan (if any), then a 25k/250k/1M credit pack (1-year validity), then post-paid at standard rates.
Measured performance (our own testing, April 2026)
- Round-trip latency: competitive with top providers on Flash TTS stack
- TTS quality MOS: high (built-in multilingual is robust); lower than ElevenLabs Multilingual v2 on edge cases
- Reconnect behavior: RTC-native, handles network hiccups cleanly
Pros
- ✅ ~990 free Conv AI minutes every month on every plan (Free Trial + post-paid included; AI plan gating removed in 2026)
- ✅ No plan gating — use Conv AI from Free Trial or post-paid
- ✅ Built-in TTS and STT (one bill, one pool)
- ✅ China Mainland native compliance for global deployments
Cons
- ❌ Voice-agent framework less polished than LiveKit Agents or ElevenLabs Agents Builder
- ❌ English documentation lags the Chinese version in some areas
Best for: bursty workloads; AI-first MVPs; teams wanting recurring free minutes; global products that need China Mainland coverage.

- ❌ Pro plan ($99/mo) is the first tier with realistic production volume
Best for: teams where voice brand/quality is the core product differentiator (media, entertainment, premium consumer apps); enterprises with budget for best-in-class TTS.
3. Vapi — BYO-stack flexibility, $0.05/min platform fee
Homepage: vapi.ai · Pricing: vapi.ai/pricing
Quick specs
- Platform fee: $0.05/min (Vapi orchestration only)
- LLM: BYO, $0.01–$0.15/min depending on model choice
- STT: BYO, $0.01–$0.04/min (Deepgram Nova ~$0.01)
- TTS: BYO, $0.02–$0.10/min (Deepgram Aura $0.02, ElevenLabs Multilingual v2 $0.10)
- Telephony: Twilio/Vonage at cost (~$0.01–$0.02/min + $1–2/mo per phone number)
- Free credit: $10 signup credit (≈65 min on budget stack)
- Plan tiers: Pay-as-you-go, Scale, Enterprise — specific tier pricing not consistently published
Real-world all-in pricing
Vapi's "$0.05/min" is the platform fee only — it's the orchestration layer. Third-party 2026 Q1 analyses (pxlpeak.com/blog/ai-tools/vapi-pricing-breakdown and others) consistently show real all-in cost:
| Stack | Components | Total /min |
|---|---|---|
| Budget | Vapi + GPT-4o mini + Deepgram Nova + Deepgram Aura + Twilio | $0.115 – $0.15 |
| Standard | Vapi + GPT-4o + Deepgram Nova + ElevenLabs Turbo v2 + Twilio | $0.22 – $0.28 |
| Premium | Vapi + Claude Sonnet or GPT-4o (with tools) + Deepgram Nova + ElevenLabs Multilingual v2 + Twilio | $0.35 – $0.42 |
Monthly budget estimates from the same analyses:
| Volume | Total cost estimate |
|---|---|
| 500 min/mo | $75 – $200 |
| 2,000 min/mo | $300 – $800 |
| 10,000 min/mo | $1,500 – $4,000 |
| 50,000 min/mo | $7,500 – $20,000 |
Hidden costs to budget for
- Concurrency overflow fees when exceeding plan concurrency.
- Twilio phone number rental at $1–$2/month per number; multi-region deployments stack.
- Failed / very short calls still billed: if a caller hangs up after 3 seconds, you still pay the 3-second LLM/TTS/STT fees. Scam or robocall traffic can burn budget quickly.
- Development time: building a production voice agent on Vapi typically takes 20–40 engineer-hours, or $2,000–$4,000 in labor before the first call.
Pros
- ✅ Maximum flexibility — swap any component
- ✅ $0.05 platform fee is transparently stated
- ✅ Good developer tooling and docs
- ✅ Pay-as-you-go with no monthly base
Cons
- ❌ "Cheap" headline becomes expensive once you add components
- ❌ Stack management burden (ops complexity)
- ❌ No recurring free minutes
- ❌ Development time is a real line item
Best for: engineering-first teams that want full control of the stack; teams with existing preferences for specific LLM/STT/TTS vendors; experimentation and prototyping.

Scenario-based recommendations
"Small budget, MVP, <5,000 min/mo" → TRTC. The ~990 free Conv AI minutes every month, on every plan including post-paid, materially reduce MVP burn. Most other vendors' free tiers are either minimal (ElevenLabs Free 15 min) or one-time (Vapi $10 credit, Agora 300-min trial).
"Premium voice brand is the product" → ElevenLabs Agents. TTS quality is still the category benchmark. Pro plan ($99/mo) is the reasonable production entry point.
"Engineering-first, want full BYO control" → Vapi. Only choice where you swap every component. Budget realistically for all-in cost $0.15–$0.42/min, not $0.05.
"Already on HighLevel CRM, agency reselling" → GoHighLevel Voice AI. Integration trumps per-minute math if HighLevel is already your system of record.
"Enterprise Voice AI pricing" (search intent) → All four vendors offer enterprise custom pricing at 50,000+ minutes/month. Expect 20–40% discounts from list prices. Our general guidance: benchmark against TRTC + ElevenLabs enterprise quotes before committing.
"Retell voice ai pricing" (long-tail, not in our 4-vendor lineup) → Retell AI positions at $0.07–$0.15/min all-in, pricing between ElevenLabs and budget Vapi configurations. Consider for high-volume outbound workloads.
"LivePerson voice ai pricing" → Enterprise-only quote model; not in the same SMB/mid-market space as this comparison.
FAQ
How much does Voice AI cost per minute? Published hosting rates range from $0.05/min (Vapi platform fee) to $0.08/min (ElevenLabs Agents) to $0.10/min (TRTC, Agora). Real all-in rates including LLM/TTS/STT/telephony typically land between $0.12 and $0.42/min. GoHighLevel Voice AI rates are not publicly disclosed.
Is ElevenLabs Voice AI worth it? If voice quality is differentiating for your product, yes — ElevenLabs still has the best TTS in the category. If you're building a commodity voice agent and quality-MOS differences of 0.2–0.3 don't matter to your users, a cheaper option delivers equivalent business value.
What's the cheapest Voice AI platform in 2026? At the hosting layer: Vapi ($0.05/min platform fee). In terms of real-world all-in cost for small-to-medium volumes: TRTC, because the recurring ~990 free Conv AI minutes per month can zero out the first $99 of your monthly bill.
Can I get free Voice AI minutes? Yes. TRTC offers the largest recurring free bucket (~990 Conv AI min/month, every plan including Free Trial + post-paid, via 10.10× ratio). ElevenLabs Free gives 15 min/month. Vapi gives a one-time $10 credit. GoHighLevel usage is tied to your CRM plan.
Is Vapi cheaper than ElevenLabs? Only at the headline platform-fee level ($0.05 vs $0.08). Real-world: Vapi's BYO stack typically totals $0.115–$0.42/min once components are added; ElevenLabs's $0.08 flat rate with built-in TTS and STT often lands cheaper for standard stacks. Vapi wins when you have strong preferences on specific LLM/STT/TTS providers.
What does "voice ai pricing per minute" actually include? Depends on the vendor. ElevenLabs's $0.08/min includes hosting + TTS + STT; LLM tokens are separate. Vapi's $0.05/min includes orchestration only; LLM, TTS, STT, and telephony are all separate. TRTC's $0.10/min includes hosting + TTS + STT; LLM is separate. Always ask: "What's in, what's out."
Is GoHighLevel Voice AI included in GHL subscription? Voice AI is metered per sub-account on top of your HighLevel plan. The Unlimited and Agency/SaaS Pro plans give you reseller billing controls (so you can pass the cost to your own customers at a markup).
What's the best enterprise Voice AI option? Define "enterprise" first. For 50,000+ min/month with custom compliance (HIPAA, SOC 2, data residency), expect custom quotes from all vendors. Benchmark TRTC Enterprise, ElevenLabs Business/Enterprise, and a direct SAP/LivePerson quote before committing.
