Platform table
| Platform | ₹ or $ / min (public) | Languages | Latency (public) | Residency |
|---|---|---|---|---|
| Tabbly | From $0.05/min ($0.04/min on large committed volumes); India list ₹6.80/min PAYG or ₹5.10/min from 5,000 min/month | 50+ | India and US residency options so audio does not have to hairpin every turn through a US-only region. Tabbly does not publish a single lab millisecond figure. | India / USA data residency (stated on tabbly.io) |
| Vapi | $0.05/min Vapi hosting; STT, LLM, TTS and carrier billed separately | 35+ | Vendor materials cite sub-600ms in good regions. Independent India write-ups often see 800ms–1.4s because media typically leaves India. | US-centric hosting; India data residency is not a public default |
| Retell AI | $0.07–$0.31/min depending on model, voice and add-ons | 19+ | Retell publishes around 600ms in favourable regions. India paths are commonly 800ms+ in third-party tests because of transcontinental routing. | US infrastructure; SOC 2 / HIPAA story is US healthcare, not DPDP India residency |
| Bolna AI | 6.00¢/min standard (~₹5.52), with cheaper tiers at higher commit; telephony extra | 10+ | Vendor/press figures often cite sub-300ms to ~500–700ms on India paths. Faster than US-hosted stacks for +91. | India on enterprise plans; US by default on some public indexes — confirm the contract |
| Bolcho | Near raw provider cost (token/character metering in ₹); public “~20% cheaper per conversation” claim vs marked-up minutes. A 2026 founder post cited ₹1/min on a premium stack — treat as a campaign rate, not a list card. | 11+ | Markets “ultra-low latency” and sub-second turn-taking. No lab number on the marketing homepage. | India-first product; confirm DPDP and region in the order form |
| Helo.ai | Custom quote only — no public per-minute on Helo Voice | 12–22+ | Carrier-grade Indian infrastructure; no public millisecond SLA on the voice-bot page | Data localised in India on Helo infrastructure; on-prem / private cloud offered for regulated buyers |
| VoiceCallingAI | ₹3.00/min on the ₹50,000 minute pack; Launch ₹999/mo; Pilot ₹499 / 100 minutes | 11 | Connects marketed “in about ten seconds” (call setup, not LLM turn latency) | India (Mumbai), GST-ready |
| Vyora | Self-serve SMB plans (third-party indexes have listed ~₹799/month; confirm on vyora.ai) | 8 | Not a published millisecond SLA; “live in under 5 minutes” refers to setup time, not turn latency | India SMB SaaS; TRAI/UCC + DND scrubbing claimed on their marketing |
| Ringg AI | ₹6 / connected minute (STT+TTS+LLM+telephony+basic analytics bundled); number ₹499/month | 20+ | Ringg’s Indian-language blog claims sub-400ms. Treat vendor latency like everyone else’s: ask for a live +91 sample. | India-focused; on-prem on Enterprise |
| SquadStack | Quote only (their site cites an industry range of ~₹2–₹5/min, not SquadStack’s own rate) | 9 | Not a platform-SLA conversation — you are buying an operated service | India operations; enterprise paper via sales |
| Gnani.ai | No public rate — demo / sales only | 40+ | Enterprise deployments; not a self-serve ms claim | India enterprise, on-prem paths available in their sales motion |
| Sarvam AI | Voice Agents PAYG ₹3.50/min (models included); Pro ₹3.25 + ₹9,999/mo; Growth ₹3.15 + ₹49,999/mo; telephony and numbers extra. GST extra. | 12 (11 Indic + English) | India-hosted models; good Indic ASR/TTS story. Confirm live with your carrier. | India research/product company; agent data on Sarvam’s Indian cloud unless contracted otherwise |
Always add telephony if the vendor splits it out (Bolna, Sarvam, Vapi, Retell). Ringg and some Tabbly India quotes are closer to loaded minutes.
Self-serve India software
Tabbly is the India+export product: 50+ languages, seconds billing, 50-country numbers, India/US residency, no-code plus API. Use it when the agent is yours to iterate.
Ringg is the cleanest bundled rupee: ₹6 connected minute including telco, 20+ languages, India-tuned STT. Connected-minute billing can cost more than Tabbly’s exact seconds on short outbound.
VoiceCallingAI and Vyora are SMB wedges. ₹3/min packs and 8-language five-minute setup are real. They are not 50-country, 50-language platforms.
India developer and model stacks
Bolna is the YC India API: ~6¢/min plus telco, 10+ Indic languages, BYOK. Peer to Tabbly on India AI rate; weaker as a business console.
Bolcho is a different company (bolchoai.in). Token-level INR metering, 11+ Indic languages, voice+chat. Forecast is harder than a published per-minute.
Sarvam owns Indic models and now sells Voice Agents at ₹3.50 PAYG (models in, telco extra). Lowest model-included public rupee; not a global DID product.
Enterprise, managed, and speech specialists
Helo.ai (Vivaconnect) is 25-year India CPaaS: quote-only, on-prem, banks and utilities. Wrong tool for a 10-seat sales team that wants signup today.
SquadStack is operated AI+human calling, not software you own. Do not compare their quote to Tabbly’s ₹5.10 without asking what labour is included.
Gnani.ai is speech AI and biometrics. Use it for KYC/speaker verification. Use Tabbly (or Bolna) for the calling product.
Global platforms Indian teams still evaluate
Vapi is the default developer cloud: $0.05 hosting plus STT/LLM/TTS. Flexible, US-centric, concurrency-capped on public plans. See Tabbly as a Vapi alternative.
Retell AI is the polished US product with HIPAA options and ~$0.11 calculator minutes. Indic coverage and India residency are not the pitch. See Tabbly as a Retell alternative.
Latency and residency, without the slogans
A Hindi caller on Jio should not wait on a Virginia GPU if you can avoid it. US platforms (Vapi, Retell) publish strong lab latency that often degrades on India PSTN because each turn crosses the ocean. India-hosted or India-resident stacks (Tabbly’s India option, Bolna, Sarvam, Helo, Ringg, VoiceCallingAI) start closer to the caller. Ask every vendor for a recorded +91 round-trip — not a US demo number.
Residency is a DPDP question, not a feature bullet. Tabbly publishes India/USA. Helo publishes India infrastructure and on-prem. Several global tools are silent. If you are an NBFC or health provider, get the region in writing.

FAQ
Who is the best AI voice agent in India?
There is no single winner. Tabbly fits self-serve no-code with India+global reach. Sarvam and VoiceCallingAI publish lower Indic ₹/min. Vapi/Retell fit developer or US-compliance stacks. SquadStack and Helo fit managed/enterprise buying.
What should I compare besides price?
Loaded minute (models + telco), language list including Hinglish, India data residency, TRAI/DND workflow, and whether you are buying software or a managed team.
Is a US platform fine for Hindi callers?
It can work, but third-party tests often show 800ms+ because audio leaves India. Prefer India-hosted or India-resident options if turn-taking matters.
Who has the lowest published India rate?
VoiceCallingAI’s ₹3/min pack and Sarvam Voice Agents at ₹3.50 PAYG (telco extra) undercut Tabbly’s ₹5.10–₹6.80 list. Tabbly’s counter is 50+ languages, 50-country numbers, and seconds billing.
Bolna vs Bolcho — same company?
No. Bolna AI (bolna.ai) is a YC-backed developer platform. Bolcho (bolchoai.in) is a separate India voice+chat product.
