That Never Miss a Call
Codiste is an AI voice agent development company that builds human-like voice agents for inbound and outbound calls. They answer 24/7, qualify leads, book appointments and update your CRM, turning AI-powered customer service into revenue.
Every Missed Call Is a Lost Customer
- After-hour and weekend calls go unanswered.
- Hold times rise at peak times, and callers hang up.
- Hiring more agents to handle volume is slow and expensive.
- Rigid IVR menus frustrate callers instead of solving their problem.
AI voice agents answer instantly, at any volume, in your customer’s language.
Customers call when they are ready to act, and 78% buy from the first business that responds. When calls land after hours, at peak times or in a long queue, they go to voicemail and the customer calls someone else.
What Is an AI Voice Agent?
An AI voice agent is software that holds natural phone and voice conversations.
It uses automatic speech recognition (ASR) to hear the caller, an LLM with Natural Language Processing (NLP) to understand intent and decide what to do, and text-to-speech (TTS) to reply in a human-like voice.
Unlike an IVR or rule-based bot, it understands context, answers follow-up questions and completes tasks such as booking appointments or qualifying leads.

How Our AI Voice Agents Work
Every call runs through a real-time pipeline built for low latency, accuracy and control.
The call pipeline
Speech Recognition (ASR)
The caller’s speech is transcribed in real time, and the agent stops talking the moment the caller starts.
Understanding & Reasoning (LLM + NLP)
The agent identifies intent, tracks context across the conversation and decides the next step.
Actions & Integrations
Through APIs, the agent checks calendars, reads and updates CRMs and ERPs, and triggers workflows.
Voice Response (TTS)
The reply is spoken in a natural, brand-matched voice in the caller’s language.
Analytics, Security & Compliance
Every call is logged with a transcript and summary, protected by encryption and access controls aligned with HIPAA and GDPR.
Industry-Specific AI Voice Agents
Every industry has its own calls, compliance rules and workflows. Our voice agents are built with that domain knowledge. We also build voice agents for healthcare, legal, automotive, e-commerce and logistics.
