01 — Capabilities

Six Voice Capabilities

Inbound, outbound, ASR, TTS, multilingual, and call center integration — all on-premise.

Inbound Call Handling

AI voice agents answer incoming calls, identify intent, handle FAQs, route complex queries, and schedule appointments. Natural conversation — no IVR trees. 24/7 availability.

Outbound Engagement

Proactive follow-up calls, appointment reminders, satisfaction surveys, and lead qualification. Personalized scripts with T1 human review before graduation to autonomous calling.

ASR — Speech to Text

Whisper-based automatic speech recognition. Real-time transcription, speaker diarization, keyword spotting, sentiment detection. Processes every audio file on your GPU locally.

TTS — Text to Speech

Natural voice synthesis powered by Qwen3-Omni. Custom voice cloning for brand consistency. Multilingual output with accent control. Sub-200ms latency on-premise.

22+ Indian Languages

Hindi, Tamil, Telugu, Bengali, Marathi, Gujarati, Kannada, Malayalam, Punjabi, Odia — native-quality voice with accent-appropriate ASR and TTS models. Plus 100+ global languages.

SIP/VoIP Integration

Drop-in replacement for legacy IVR infrastructure. SIP/VoIP integration, call routing, real-time agent assist, WebRTC for browser-based interfaces. No telephony rip-and-replace.

02 — How It Works

From Call to Resolution

Every call follows the same pipeline — intake, understand, respond, learn. All on your hardware.

01
Intake

SIP/VoIP receives the call. Audio streams to your local ASR engine.

02
Transcribe

Whisper-based ASR converts speech to text in real time. Speaker diarization active.

03
Understand

LLM identifies intent. RAG retrieves context from your knowledge base. MCP pulls live data.

04
Respond

TTS generates natural voice response. Sub-200ms round-trip. Accent-matched output.

05
Log & Learn

Full transcript stored. Sentiment scored. Analytics agent surfaces patterns and gaps.

End-to-end latency: Under 200ms from caller utterance to AI response on a single NVIDIA RTX 4090. Enterprise A100 deployments sustain this at 1000+ concurrent calls.

Callers speak naturally — the AI agent routes, answers, or escalates. Live demo available in your language.
05 — The Difference

Cloud Voice APIs vs ATC Voice

Cloud voice services charge per minute and send your audio to external servers. ATC Voice runs on your hardware at zero marginal cost.

Cloud Voice APIs

  • Audio data sent to external servers for processing
  • Per-minute pricing that scales with call volume
  • 200–800ms latency (network round-trip)
  • Internet dependency — outage kills all voice
  • Generic voice models, no accent customization
  • Limited compliance options for regulated industries
  • Vendor lock-in to specific cloud provider

ATC Voice (On-Premise)

  • All audio processed locally on your GPU hardware
  • Zero per-minute costs — fixed infrastructure investment
  • Sub-200ms latency (local inference, no network hop)
  • Works offline and air-gapped if needed
  • Custom voice cloning, accent-matched TTS
  • DPDP Act compliant by architecture, not policy
  • You own the models, the code, and the recordings
06 — Use Cases

Who Uses ATC Voice

FAQ

Frequently Asked Questions

How is sub-200ms latency achieved on-premise?

Streaming ASR (Whisper-based) overlapped with LLM inference (vLLM with continuous batching) and streaming TTS. Combined audio-in to first-audio-out latency lands at 150 to 200 ms on a single A100 GPU.

How many concurrent calls can ATC Voice handle?

A single A100 80GB GPU handles roughly 30 concurrent voice sessions at sub-200 ms latency. Scales linearly across additional GPUs; reference deployments handle 1,000+ concurrent calls.

Which telephony stacks does ATC Voice integrate with?

SIP (Asterisk, FreeSWITCH), WebRTC, Twilio Voice, Exotel, and Plivo via SIP trunks. PSTN integration available through certified telecom partners in India.

What languages and accents are supported?

100+ languages with native ASR and TTS. Indian-language coverage includes Hindi, Bengali, Tamil, Telugu, Marathi, Gujarati, Kannada, Malayalam, Punjabi, Odia, and Assamese with regional accent tuning.

Can it handle code-switching (Hinglish)?

Yes. Indian voice agents commonly mix Hindi and English (Hinglish) within sentences; ATC Voice ASR and TTS are fine-tuned on code-switched corpora to handle this natively.

Is call recording and transcript storage compliant?

Yes. Recordings and transcripts are stored on your infrastructure, encrypted at rest, with role-based access and DPDP-aligned consent prompts at the start of every recorded call.

Can ATC Voice make outbound calls?

Yes — for collections, surveys, appointment reminders, and renewal nudges. Outbound dialling respects DND registers and includes per-campaign frequency caps and human-handoff thresholds.
