Google’s agent, by the second

Here is how Dialogflow and Frequency differ.

Dialogflow CX is Google's agent builder on Google's own speech and models, billed per second of audio, with a free trial and a Mumbai region. Its phone gateway stops at US numbers. We sell the whole call for callers in India: Hindi, Gujarati, Tamil, Telugu and English on our own GPUs, one price a minute in rupees, and the phone line inside it on pay as you go.

Dialogflow CX is a serious builder. Flows for the parts of a call you want to control, Playbooks for the parts you want a model to handle, and Google’s speech and voices behind both. If your company already lives on Google Cloud, it fits.

The gap is the phone. Its Phone Gateway supports US numbers only. For a call in India you bring a SIP trunk through your own session border controller, and the carrier’s minutes are yours to arrange and pay for.

We sell the whole call. Our speech recognition, our model and our voice run on our own GPUs in India. The model is the open Gemma 4 26B. On pay as you go, the phone line and +91 numbers are inside the rate, and every call’s result lands on your webhook.

How we read these numbers

Dollar prices converted at ₹94.96, the ECB reference rate on 16 October 2026. The rate.

Each bar is one minute as Dialogflow’s own pages price it, layer by layer, beside ours from our price list. A hatched end is a part of the call their price leaves out and publishes no number for, so it has no length.

  • Dialogflow CX, Flows: platform, per second of audio ₹5.70 ($0.001 / 1 second)
  • Dialogflow CX, Playbooks: platform, per second of audio ₹11.40 ($0.002 / 1 second)

Google prices voice agents per second of audio, so a minute is 60 of them: $0.001 × 60 = $0.06 on Flows and $0.002 × 60 = $0.12 on Playbooks, which is ₹5.70 and ₹11.40 at the ECB rate. Listening time and the full spoken reply are both billed, rounded up to the nearest second. The page does not itemise speech recognition, the voice or the model, so each bar is the platform rate as printed. The phone line is not in it.

From cloud.google.com/products/conversational-agents/pricing, checked . Ours from our price list.

The chart shows the plan you choose above beside the price it pairs with: our T1 and T3 beside Dialogflow’s volume price, our T5 beside its pay-as-you-go price. Without that choice, every bar is listed.

What it costs

Google bills voice agents per second of audio. Flows are $0.001 / 1 second and Playbooks $0.002 / 1 second. As a minute, that is $0.06 and $0.12, or ₹5.70 and ₹11.40 at the ECB rate. Both the time the agent spends listening and the full length of its reply count, rounded up to the nearest second. If the caller cuts the agent off, the whole reply is still billed.

Ours is ₹5 a minute on pay as you go, with the line inside. A 1,000-minute month is ₹5,000. When your volume is steady, the volume plan brings it to ₹1 a minute. We bill in 10-second blocks, and a call nobody answers is free. The pricing guide shows how to forecast a month from your own call lengths.

Who runs each part of the call

Dialogflow CX is Google's platform on Google's own speech and models, priced per second of audio. Outside the US, the phone line is yours to bring. We are the models and the platform, with the line inside the price.

Which to pick

Which is right for you?

Sometimes it's them. We'll say so.

Choose Dialogflow if…

  • You already run on Google Cloud and want the agent next to your data stores and your SBC.
  • Your security review asks for HIPAA, ISO 27001, SOC 2 or FedRAMP High.
  • You need Bengali, Marathi, Kannada or Malayalam today. Dialogflow's language list has them.
  • You want deterministic flows and generative playbooks in one builder, with $600 and $1000 of trial credit.

Choose Frequency if…

  • Your customers are in India and call +91 numbers. Ours come with the product.
  • You want one price per minute, in rupees, with the phone line inside it.
  • You want the call to run on GPUs in India, not only the data at rest.
  • You make a lot of calls. Our agents cost ₹1 a minute on the volume plan.

Where Dialogflow is ahead

Dialogflow’s language list is longer than ours today: Bengali, Marathi, Kannada and Malayalam are on it, and we have them marked as coming. Its compliance page lists HIPAA, ISO 27001, SOC 2 and FedRAMP High. A new account gets $600 of trial credit on Flows and $1000 on Playbooks. And it has a Mumbai region for the agent and its data at rest, though Google’s AI/ML Data Location commitment covers only US and EU locations.

We cannot transfer a live call to a person yet, and a new workspace starts with 5 calls at a time, raised when you ask.

Moving

Moving your agent across is easy.

Bring the agent you have. Most of it carries across.

  1. Step 1

    Open the sandbox.

    Look around with no sign-up. We ask for an email only when you test a call.

  2. Step 2

    Bring your prompt.

    Paste the prompt you already wrote into Agent Studio, and pick a voice and a language.

  3. Step 3

    Talk to it. Go live.

    Test it in your browser or on your own phone, then go live the same day.

Open the sandbox

Moving a flow across

A Dialogflow flow is a graph of pages and routes. That maps onto a node-based agent here: each page becomes a node, each route a branch, and Agent Studio can draft the first version from a few of your recordings. A playbook becomes a prompt-based agent: paste the instructions, pick a voice and a language. Your webhooks move to one signed webhook per call, with the transcript and the outcome in it. The India API guide walks through the rest.

Then put both on your own phone, with your real script and the English words your callers drop into Hindi, and listen.

Questions

Here is what people ask before switching from Dialogflow.

What does a 1,000-minute month cost on Dialogflow CX?

At $0.001 / 1 second on Flows, 1,000 minutes of audio is $60, about ₹5,698 at the ECB rate, before your SIP trunk and the carrier's minutes. On Playbooks it is twice that. On our pay-as-you-go plan the same 1,000 minutes cost ₹5,000, with the phone line included.

Does Dialogflow CX speak Hindi?

Yes. Hindi is on its language list with every feature ticked, and Google's Chirp 3 HD voices include Hindi (India). Hindi, Gujarati, Tamil, Telugu and English are live in our speech recognition and our voice, and the agent moves into English mid-sentence the way callers do.

Can I get an Indian phone number through Google?

Not through Dialogflow. Its Phone Gateway is limited to US phone numbers. For India you bring a SIP trunk from your own session border controller or a partner integration. We sell +91 numbers, or you connect the Plivo number you already have.

Does my call stay in India?

On Dialogflow, the agent and its data at rest can sit in Mumbai (asia-south1), but Google's AI/ML Data Location commitment covers only US and EU locations. Every call with us runs on our own GPUs in India.
