Our Capabilities

End-to-End Voice AI Services

From AI inbound agents to outbound campaigns and CRM integrations — we build voice automation that handles real customer calls.

AI Inbound Call Handling

Deploy voice AI agents that answer every inbound call instantly — greet callers, understand intent, resolve queries, and escalate to a human only when needed.

Speech-to-Text & NLU

Powered by OpenAI Whisper and advanced NLU models, our agents understand natural speech — accents, interruptions, and complex queries — not just keyword triggers.

AI Voice Agents

Build human-like voice agents using ElevenLabs TTS and GPT-4o — agents that hold full, context-aware conversations, remember prior turns, and adapt in real time.

Outbound Call Automation

Launch automated outbound call campaigns for lead follow-ups, appointment reminders, payment nudges, and re-engagement — at scale, without a single rep dialling.

CRM & Tool Integrations

Sync every call, transcript, and outcome bi-directionally with HubSpot, Zoho, Salesforce, or any CRM — so your team always has full context without manual logging.

Call Analytics & Reporting

Track call volumes, resolution rates, agent performance, escalation triggers, and conversion rates through real-time dashboards — know exactly what's working.

Why Choose Mind Stack Labs

Start Your Project

Does the voice agent sound robotic?

Not at all. We use ElevenLabs text-to-speech — the industry's most natural-sounding voice synthesis. Callers regularly can't tell they're speaking to an AI, especially after we fine-tune the voice to match your brand tone.

Can the agent handle complex or unexpected queries?

Yes. GPT-4o handles natural, open-ended conversations. When the agent encounters something truly outside its scope, it smoothly hands off to a live agent — with full context passed over so the caller never has to repeat themselves.

What languages and accents does it support?

Our agents support 30+ languages out of the box via OpenAI Whisper and ElevenLabs. We tune each deployment for regional accents and dialects relevant to your customer base.

Will I own the voice agent after delivery?

Yes. You receive complete ownership of all scripts, prompts, flows, and integrations. Everything is fully documented and handed over — with an NDA and IP assignment agreement included.
