Overview
Smallest AI's Voice AI Platform (Atoms) is an enterprise-grade platform for building and deploying AI voice and chat agents that handle real customer conversations with human-like fluency. Powered by proprietary AI models built in-house.
CORE TECHNOLOGY
Atoms is powered by three proprietary AI models developed by Smallest AI:
Pulse (Speech-to-Text): High-accuracy transcription optimized for Indian accents and multilingual conversations, including code-mixed speech like Hinglish.
Lightning (Text-to-Speech): Ultra-low-latency voice synthesis with human-like speech, custom voice cloning, and multiple Indian language voices with sub-200ms first-byte latency.
Electron (Small Language Model): Purpose-built for voice conversations, enabling intelligent dialogue management, context retention, and real-time decision-making within calls.
These models can also be deployed independently in a customer's VPC for enterprises requiring complete data sovereignty.
PLATFORM CAPABILITIES
Atoms is a no-code agent builder that allows enterprises to design, test, and deploy AI agents that function as AI employees - handling end-to-end workflows across support, sales, and operations using your business context, tools, and data.
Hyper-realistic voice agents supporting any language with complete conversation handling. Integrations into CRMs, contact center stacks, and business systems for automated task completion. Enterprise-grade performance with high accuracy, low latency, and continuous learning capabilities.
TARGET VERTICALS IN INDIA
BFSI: Automate collections, loan servicing, KYC verification, insurance claims, and policy servicing. Insurance: Policy renewal reminders, claims FNOL, lead qualification, and cross-sell campaigns. Telecom: Customer support automation, plan upgrades, complaint resolution, and retention campaigns. E-commerce and Retail: Order status, returns, delivery coordination, and post-purchase engagement. Healthcare: Appointment scheduling, prescription refills, patient follow-ups, and insurance verification.
DEPLOYMENT

Highlights
- One listing for Smallest AI's complete voice stack: deploy no-code Atoms voice and chat agents that handle end-to-end customer conversations, or consume the underlying proprietary models directly: Lightning (text-to-speech) and Pulse (speech-to-text). Mix and match across 20+ languages for support, sales, and operations with sub-second, human-like conversations, all under a single AWS subscription with consolidated billing.
- Production-grade real-time performance: Lightning streams broadcast-quality 44.1 kHz speech at ~100 ms latency with instant voice cloning from 5-15s of audio across 15 languages; Pulse returns first transcripts in ~64 ms with speaker diarization, PII/PCI redaction, and keyword boosting across 38 languages. Both are built for noisy, accented, far-field, and telephony audio, with HTTP, SSE, and WebSocket streaming.
- Enterprise-ready and consolidated on AWS: usage-based pricing with monthly or annual commits, private offers and custom MSAs for committed-use deals, and the ability to draw down existing AWS commitments. Deployable across AWS regions with data-residency options and in-VPC model deployment for full data sovereignty, backed by SOC 2 Type II and PCI-DSS. Ideal for trials, POCs, and scaling to production.

Pricing
Pricing is based on the duration and terms of your contract with the vendor, and additional usage. You pay upfront or in installments according to your contract terms with the vendor. This entitles you to a specified quantity of use for the contract duration. Usage-based pricing is in effect for overages or additional usage not covered in the contract. These charges are applied on top of the contract price. If you choose not to renew or replace your contract before the contract end date, access to your entitlements will expire.
Additional AWS infrastructure costs may apply. Use the AWS Pricing Calculator to estimate your infrastructure costs.

Dimensions summary
This listing groups pricing around four products you can buy as contracts. The Atoms Business Plan covers voice agents with included minutes, then charges per minute beyond that. Lightning TTS offers Business and Enterprise plans for text-to-speech, each with included minutes. Pulse STT works the same way for speech-to-text. The Electron SLM Plan covers the language model, with token usage billed through separate overage units measured in millions of tokens. Overage dimensions for Lightning TTS, Pulse STT, and Electron input, cached, and output tokens let you pay for usage past your committed amounts. Enterprise plans require contacting the vendor.
Top-of-mind questions for buyers
A voice agent minute measures talk time on a call. The plan includes 16,667 minutes. Once you pass that, each additional minute bills through per-minute overage. Model choice and architecture affect per-call cost, since cascading and speech-to-speech setups combine different hosting, transcription, and speech layers.
The Electron SLM Plan gives you access to the language model. Token usage bills through separate overage units, where one unit equals one million tokens. Input tokens, cached input tokens, and output tokens each have their own overage dimension, so each token type is counted and billed on its own.
The Lightning TTS Business Plan includes up to 115,730 minutes of generated audio. The Pulse STT Business Plan includes up to 399,800 minutes. Usage past these amounts bills through the matching overage dimension, measured per minute. The included amount and overage appear as separate line items on your invoice.
