Gnani and ElevenLabs are pushing voice agents into Indian phone conversations, but a convincing demo is only the starting point. The real test is whether speech remains understandable on compressed 8kHz calls, whether agents handle code-switching and interruptions, and whether each deployment meets India’s consent, privacy, disclosure and sector-specific rules. Neither vendor’s marketing claims amount to regulatory approval or an independent performance certification.
Two overlapping products with different emphases
Gnani presents a full enterprise voice stack: automatic speech recognition (ASR), text-to-speech (TTS), language models, analytics, biometrics and integrations. Its comparison material lists more than 22 languages, mid-call language switching, inbound and outbound agents, CRM and telephony connections, voice authentication, and cloud, private-cloud, on-premise or air-gapped deployment. Gnani says it supports more than 200 enterprises, handles over 30 million voice interactions daily and trained on more than 14 million hours of telephonic audio. Those are company-reported figures.

ElevenLabs puts more emphasis on natural multilingual voices and conversational-agent orchestration. Its India offering advertises 12 Indian languages or accents, code-switched speech, guardrails, escalation, India data residency and telephony connections through Ozonetel, Exotel and Plivo for inbound, outbound and handoff workflows. In an Equal customer story, ElevenLabs says the assistant handles 600,000 calls per day for more than 300,000 daily users. That scale statement is also self-reported.

How Indian telephone conditions change the result
Studio-quality speech does not represent a typical Indian customer call. Public-switched telephone network audio is often limited to 8kHz, then degraded by GSM compression, packet loss and background noise. Speakers may switch between English and an Indian language in the same sentence, use regional dialects or pronounce product and place names in ways a general model has not seen.
That makes end-to-end behavior more important than a TTS demo. Measure the time from a caller’s final word to the agent’s response, how the system reacts when the caller interrupts, whether it detects silence correctly, and how much context survives a transfer to a human. Test with native-language reviewers and domain vocabulary such as loan terms, medicines, policy numbers or account identifiers.

What the published speech benchmarks actually show
Gnani’s STT comparison reports word-error rate (WER), where a lower percentage means fewer transcription errors. The figures below come from Gnani publications and are not an independent audit. The datasets and test conditions differ, so they cannot establish a universal vendor ranking.
| Test | Gnani | ElevenLabs | Other reported results | What it means |
|---|---|---|---|---|
| Gramvaani, Standard WER | 22.0% | 27.5% (ElevenLabs Scribe) | Microsoft 26.4%; Sarvam 23.4%; Deepgram Nova 34.0% | Gnani’s published comparison shows a lower error rate on this dataset. |
| Kathbath Noisy post | 17.5% | 19.1% | Not stated in the cited comparison | Another Gnani-published noisy-speech comparison; it uses a different dataset. |
WER does not capture every production failure. A transcript can be technically close yet omit a negation, confuse a customer number or mis-handle a language switch. Conversely, a slightly higher WER may be acceptable if the agent asks a precise clarification question and transfers the call safely. Run acceptance tests on de-identified recordings from the intended region and use outcome measures such as successful authentication, completed service requests, transfer accuracy and complaint rates.

India’s regulatory test is layered, not a single “AI-call” rule
Whether an AI call is lawful depends on the workflow, the data collected and the sector involved. Gnani’s buyer guide identifies the Digital Personal Data Protection (DPDP) framework, Reserve Bank of India (RBI) requirements, Insurance Regulatory and Development Authority of India (IRDAI) requirements, and Telecom Regulatory Authority of India (TRAI) consent and do-not-disturb (DND) obligations as potentially relevant. An inbound support call, an outbound sales campaign, collections, KYC, healthcare and insurance can therefore require different controls.
Tell the caller it is AI
Gnani’s guide states: “One more rule applies everywhere: a voice agent discloses that it is AI, in the opening line of the script.” Put that disclosure before authentication or the collection of sensitive details, in the language the caller is using. Do not present a synthetic agent as a human employee.

Govern every form of call data
Recordings, transcripts and call metadata are personal data in the guide’s description. A voiceprint used for authentication is treated as sensitive biometric data. Define the lawful purpose, access roles, retention period, deletion process and storage locations before connecting the number. India data residency can constrain where recordings and transcripts are processed or backed up; it does not by itself prove that a deployment satisfies DPDP or a sector regulator.

Control consent, DND and calling windows
Confirm consent capture, DND suppression, permitted calling hours and opt-out handling with the telephony and compliance teams for the target use case. A vendor’s product page is not a regulatory authorization. Keep an auditable record of the script version, consent event, number screening result, agent actions and any human escalation.

What to compare before choosing a platform
| Decision area | Questions to answer in a pilot |
|---|---|
| Voice and language | Does the selected voice sound natural for the target region, and can it switch languages mid-call without losing names or numbers? |
| Recognition on telephony audio | What is the error rate on your de-identified 8kHz recordings, with noise, accents and code-switching? |
| Latency and interruption | Can callers barge in, correct the agent and receive a response quickly enough for a normal conversation? |
| Telephony and CRM | Are inbound and outbound numbers, call recording, disposition codes and CRM context available through your existing providers? |
| Handoff | Does a human receive the transcript, intent, authentication state and unresolved issue without forcing the caller to repeat everything? |
| Deployment and residency | Can the provider meet your cloud, private-cloud, on-premise or air-gapped requirement, and where are audio, transcripts and backups stored? |
| Biometrics | If voice authentication is used, what consent, access control, revocation and fallback process protects the voiceprint? |
| Cost | What is the unit price for minutes, completed calls or other usage, and what is the total cost per successfully resolved case? Public prices are generally not disclosed. |
A defensible pilot plan
- Classify the workflow. Document whether it is support, sales, collections, KYC, healthcare, insurance or another regulated activity, then map the relevant consent and calling restrictions.
- Prepare representative audio. Remove identifying details from real calls while preserving 8kHz quality, background noise, regional accents, code-switching and domain terms.
- Write the opening and fallback scripts. Include the AI disclosure, purpose, recording notice where required, opt-out path and a clear route to a human.
- Measure the whole conversation. Track WER, latency, interruption recovery, intent accuracy, authentication errors, transfers, repeat explanations and completed outcomes—not just voice naturalness.
- Test failure deliberately. Use silence, overlapping speech, anger, ambiguous answers, unexpected language switches, network degradation and requests outside the agent’s scope.
- Audit the evidence. Verify retention, deletion, access logs, residency, vendor subprocessors and the export of transcripts and call metadata before production approval.
Bottom line for buyers
Gnani and ElevenLabs may make Indian-language phone agents sound substantially more natural than older menu-driven systems, and both report large-scale deployments or enterprise use. The published WER figures are useful starting evidence, not a guarantee for your customers’ calls. Choose only after a controlled pilot demonstrates acceptable noisy-line recognition, latency, code-switching, human handoff and auditability—and after legal and compliance owners approve the exact calling workflow.
