AI agent development company Belitsoft develops custom voice AI agents that can answer phone calls, understand what the caller wants, pick up on context and tone, and speak as naturally as a human.
If you do not want to build an AI agent from scratch, we help you choose the right AI agent development platform based on response speed, how good it can connect with your existing systems, your budget, and how your staff works, not just on who offers the most features.
What the Custom AI Voice Agent Solution Can Do
A voice AI agent works in real time - listens, understands the request, connects to your internal systems, completes the task, and confirms the result on the same call. It responds fast, does not talk over people, handles interruptions, and can complete tasks in your systems while staying on the call.
During the call, the Ai voice agent can book appointments, check billing, take payments, update records, and transfer to a human when request falls outside defined rules or confidence levels. The caller doesn't need to repeat information during the transfer. An AI voice agent passes the call to a human with the full context attached.
A voice AI agent lets you automate full customer conversations from lead qualification and product demos to onboarding, renewals, collections, or post sale support. A voice AI agent platform can scale to very high volumes, even up to one million simultaneous calls, after configuring telephony and cloud for that.
What Benefits Custom AI Voice Agent Brings
AI agents can cut support costs, and reduce missed calls by 50%, process 100% of inbound calls with a 30% transfer rate, achieve a 100% increase in resolution rate, ensure 100% consistent messaging tone and language, maintain sub-500 ms latency, and deliver an average response time under 7 seconds.
Voice AI agent deployment can automate 60%+ customer support across dozens of products in several weeks. Significant reductions in operational costs in labor-intensive areas result from cutting down wait times and boosting response efficiency, effectively multitasking during peak times and after hours, and reducing operating and staffing expenses. The result fosters stronger customer relationships and loyalty, boosting engagement, satisfaction, and long-term retention.
Custom AI Voice Agent Develop, Implementation & Support
We manage the entire cycle of agent creation, from requirement gathering and design to implementation, testing, and deployment, making seamless integration with existing business systems, smoothly and without unforeseen risks.
We identify which agent type best fits your industry-specific use cases, prepare high-quality data for training your LLMs, create ground-up model architectures, and fine-tune pre-trained foundation models.
We develop dialogue models and voice personalities, continuously monitor performance, and quickly address issues as they arise.
Our certified agentic AI experts serve trading, financial services, healthcare, and other verticals. Professional forward deployment engineer-led implementation ensures a smooth and secure deployment, fully managed. We help you avoid model lock-in, choose from the largest LLM providers, or bring your own model.
We analyze agentic Voice AI platforms' pricing model, measure response delays during call, test how easily the AI agent platform connects to your systems, and check how fast it's possible to adjust prompts, workflows, and rules. Then we select an AI agent platform that fits your call types, launch a small pilot, review recordings and metrics, and help you scale from there.
