Numbers, attacks and comparisons.

What we measured on one laptop, what we threw at the agent, and how Auralis compares.

Measured, not promised.

Measured on one Apple M4 laptop with 16 GB of memory. Speed numbers use local models and no cloud keys unless a line says Groq.

Speed

Hindi is slower than English: first sentence of the answer 3.07 s against 1.89 s. The Groq figure comes from 10 turns; the other 20 fell back to the local model after the free tier ran out. These times start when the audio request is sent, not when the caller stops speaking. Read-back error (7.6% English word error, 7.1% Hindi character error) measures how a speech recogniser hears the voice, not how natural it sounds.

Every number, method and the commands to rerun them are in the project's results file, shared on request.

Attack your agent before anyone calls it.

One click sends 6 difficult callers at your agent. A second model grades each reply against a written expected behaviour.

A quick self-check, not a certification.

How Auralis compares.

A plain comparison with how hosted voice-agent platforms work. Our numbers are measured; theirs are quoted from their own public pages, with the month we read them.

  • Price per minute

    Auralis (local)

    No per-minute fee. You pay for your own computer's power; we have not measured that cost.

    Auralis (+ Groq)

    Groq charges by the token. We have used only its free tier, which runs out after a day of heavy testing; a paid tier is untested.

    Typical hosted voice-agent platform

    Vapi: $0.05 a minute for hosting alone, with speech, model, voice and phone costs added. Retell AI: $0.11 a minute in its default estimator (voice infrastructure $0.055, model $0.04, voice $0.015, phone $0).

    Vapi pricing, Oct 2026; Retell AI pricing, Oct 2026

  • Where audio and data live

    Auralis (local)

    On your laptop: audio, documents, voices and receipts. No cloud keys needed.

    Auralis (+ Groq)

    The caller's audio, and the question with the document passages it uses, go to Groq. Voice synthesis, watermark and receipts stay on your laptop.

    Typical hosted voice-agent platform

    On the platform's servers and those of the speech, model and voice vendors it routes to. Vapi's page names Deepgram, OpenAI and ElevenLabs.

    Vapi pricing, Oct 2026

  • Works offline

    Auralis (local)

    Yes, once the models are downloaded. The measurements here used no cloud keys.

    Auralis (+ Groq)

    No, it needs the internet. When Groq's limits run out it falls back to the slower local model.

    Typical hosted voice-agent platform

    No. It is a web service.

  • Consent-checked cloning

    Auralis (local)

    Yes. The speaker says a fresh sentence and code aloud; it is transcribed and a speaker check compares it with the sample. A consent record is kept and withdrawal deletes the voice.

    Auralis (+ Groq)

    Yes, the same checks. Cloning runs on your laptop.

    Typical hosted voice-agent platform

    Not checked.

  • Watermark and public verify

    Auralis (local)

    Yes. Every clip and reply gets an inaudible watermark and a signed receipt, and anyone can check a clip on the Verify page. Detected 70 of 70 times after MP3, WhatsApp-style and phone-line audio; speed or pitch changes can remove it.

    Auralis (+ Groq)

    Yes, the same.

    Typical hosted voice-agent platform

    Not checked.

  • Indian languages

    Auralis (local)

    Speech in 22 Indian languages with preset voices, and your own consented voice in Indian languages with DhVaani. Live agent replies are in English, Hindi and Hinglish.

    Auralis (+ Groq)

    The same voices. Groq's Qwen model answered Hindi, Marathi and Hinglish correctly in our checks.

    Typical hosted voice-agent platform

    Depends on the speech and voice vendor you plug in. Vapi's docs give language counts per provider, not a list of Indian languages.

    Vapi multilingual docs, Oct 2026

  • First response time

    Auralis (local)

    First sentence of the answer 2.23 s median (3.58 s at p95); full reply 3.02 s. 30 questions, 16 Oct 2026.

    Auralis (+ Groq)

    First sentence 2.52 s; full reply 2.81 s. The 10 turns Groq answered, 15 Oct 2026.

    Typical hosted voice-agent platform

    Twilio's guide sets a 1.1 s (1,115 ms) mouth-to-ear target for a cascaded voice agent. That is a published target, not a measured product, and its clock starts when the caller stops speaking, so it is not like-for-like.

    Twilio, Core Latency in AI Voice Agents, Nov 2025

Hosted-platform figures are quoted from Vapi's and Retell AI's own public pages and Twilio's guide as read on 17 October 2026; the pricing pages show no publication date, so the month is when we read them. Prices change, so follow the links. "Not checked" means we did not review those vendors' policies.

What Auralis does not do yet

  • WhatsApp is not live-tested

    Voice notes work against a simulated WhatsApp service. It needs a Meta test number before we can say it works on a real phone.

  • Phone calls: trial account only

    Outbound calls through Exotel were tested live once on a trial account. Receiving calls on your own number is untested.

  • Windows is untested

    A Windows set-up script exists, but nobody has run Auralis on a Windows machine with a graphics card yet.

  • No paid language-model tier yet

    The fast answers use Groq's free tier, which runs out after a day of heavy testing. Replies then come from the slower local model.

  • Tight on a 16 GB Mac

    With every model loaded, a 16 GB Mac can swap 3 to 5 GB to disk. The biggest Indian-language voice alone needs about 7 GB.

  • Indian-language voices are not live

    Indian-language preset and cloned voices take several seconds per sentence on a laptop, so they suit Studio renders. Live calls use English and Hindi preset voices.

Method and raw numbers are in the project's results file (shared on request). Try the Verify page yourself.

Why

Built for how India actually talks.

Three problems kept coming up. Each comes with numbers, and every number links to where it came from. Prices and dates were checked on 17 October 2026.

India is online in its own languages.

Much voice AI is still built English-first. The people it is meant to serve mostly are not.

What Auralis does

Auralis speaks in 22 Indian languages with ready voices, and can speak Hindi and other Indian languages in your own consented voice.

Hear the languages

A voice can now be copied. Trust has to be built in.

Cloned voices are used in scams, and India now has rules on labelling synthetic media and on handling personal data.

What Auralis does

Auralis asks for a spoken yes before it clones a voice, adds an inaudible watermark to its audio, and gives every clip a signed receipt that anyone can check.

How consent worksVerify a clip

Hosted voice agents are billed by the minute.

That is fine for some teams. A clinic or a college office should also have the option to own the whole thing.

  • $82 to $129

    per 1,000 minutes, Vapi's own estimate: about $0.08 to $0.13 a minute with hosting, speech recognition, a language model and a voice. Telephony is extra.

  • $0.11

What Auralis does

Auralis is free to run. The code is MIT-licensed and shared on request. It runs on one laptop, your data stays on your machine, and cloud models are optional. It adds no per-minute fee of its own. Phone calls still go through a phone provider.
