September 2022 Feature Releases

In this AI4 fireside chat, Regal.ai COO Sahil Mehta and TaskUs CCO Jarrod Johnson explore how enterprise organizations are deploying voice AI agents across customer experience, support, and sales. They share real-world deployments, discuss quality and ROI trade-offs, and outline best practices for aligning operations and product teams when adopting AI agents at scale.

Our engineering team breaks down how we improved our Voicemail Detection model by aligning the taxonomy with the actual audio, scaling labels, and choosing representations before adding model complexity.

New TCPA updates require interpreting opt-out intent and suppressing outreach across all channels. See how you can use Regal's AI Decision Node to stay compliant.

We ran the latest models from DeepSeek, Anthropic, Google and OpenAI through the Voice CX Benchmark. Here's which ones we're prioritizing for voice AI agents, and which ones we're passing on.

Last month, we shipped releases that improve your contact center operations by extracting business insights with Copilot and reducing wasted agent minutes with our new Voicemail Detection model. The result is more reliable, productive AI agents that can drive revenue for your business.

Copilot started as the place you asked questions. Over the last few months it has become the place where agents are improved, tested, and monitored.

Enterprises need voice agents that hold a natural, human-like conversation while moving each call toward its goal and staying within compliance boundaries. The Voice CX Benchmark scores models on exactly that: how well they progress the call turn by turn, how safely and clearly they communicate, and how quickly they respond.

Every qualifying voice call that runs through Regal gets two sentiment scores: one for the agent, one for the contact. Here's what actually produces those numbers.

Building a voice AI agent from scratch means writing prompts, wiring up actions, and defining guardrails before you can even test a call. Our upgraded agent templates skip that setup.

With Regal’s next-generation Voicemail Detection model, you can now classify voicemail, iOS or Google call screeners as separate categories with very high accuracy. This enables screener-specific handling, ultimately reducing missed agent connections.

Last month, we shipped releases that make it easier to build, monitor, and test agents in one interface. Copilot Canvas brings building, editing, and testing into one interface and it can work straight from your files. Multi-state sticky notes let your team document decisions directly on a live agent.

Copilot now lets your team upload files, like spreadsheets, scripts, and flowcharts, directly as inputs. This gives Copilot the context it needs from the start, making it easier to extend Copilot into new agent use cases as they come up.

How Regal AI Agents recognize, navigate, and continuously improve at getting through third-party IVR phone trees, from classification and the Press Digit action to node isolation and real-world test simulations.

Last month, we launched features that extend your management of AI agents via MCP and CCaaS platforms. Debug based on agent versions or simulation runs, and manage AI analysis data points via Copilot and Regal MCP. As a Five9 AI Agent Connect partner, Regal now has a dedicated integration API built for Voice AI agents.

Copilot Canvas brings agent building, testing, and monitoring into one interface, so you can edit, test, and track performance without leaving Copilot chat.

We've always been careful to never give frontier labs the right to keep or train on customer data. With open weight models, we can go further: when a customer invests in improving these models, that value accrues to them, not to a lab.

Last month, we shipped updates that make AI agents sound more responsive and easier to run at scale. Dynamic Voices lets your agent adjust its pace the second a contact asks for it, and Copilot now handles IVR and disposition management.

OpenAI launched GPT-Live, a new generation of voice models, and described it as a “full-duplex” model. We tested GPT-Live directly to see how the theory holds up in practice.

The Regal Observability Dashboard gives your team real-time visibility into AI agent performance — tracking hallucination rates, guardrail breaches, latency spikes, and more across every call, automatically.

Regal MCP connects your Regal platform to AI environments like Claude, Cursor, and ChatGPT. Your team can pull transcripts, inspect configurations, and trigger actions without switching context.

We reduced end-to-end voice AI response latency by 26% in three weeks by optimizing prompt structure for LLM caching: moving dynamic contact data out of the cacheable prefix so the model stops reprocessing instructions on every call.

This month, we shipped Regal MCP, which extends what your team can build, see, and improve. Regal MCP opens the platform to your external AI environment, so team members can take Regal actions directly from tools like Claude without switching context.

Behind a fragmented and ever-changing regulatory landscape is a simple goal: protecting people from unwanted or poorly timed outreach and giving them control over how they’re contacted. In practice, that responsibility translates into a set of checks that must be validated.

This number is a milestone that represents a fundamental shift in customer experience and how businesses grow. Curious what this number really looks like? We put it into perspective.

Every new LLM comes with trade-offs between latency, cost, and quality — and Regal tests all of them against real voice AI agents. Here's what we found when we ran Gemini 3.5 Flash through our benchmark.

This month, we shipped enhancements that help you quickly make proactive fixes and customize AI agents to your brand. Copilot does more troubleshooting work on your behalf and with headless WebRTC, you can embed Regal voice agents inside your own product UI.

After powering over 400 million calls, we've found that the contact centers that win with voice AI aren't just the ones that deploy first. They're the ones that learn fastest.

AI phone agents aren't just better phone trees. They are autonomous systems that can understand caller intent, retrieve relevant information from your CRM in real time, execute actions, handle objections and clarifications, and complete the conversation without human involvement.
