Microsoft’s Copilot Studio now supports real-time, interruptible voice agents for Dynamics 365 Contact Center.

Microsoft has launched real‑time voice agents in Copilot Studio, now generally available in Dynamics 365 Contact Center. These agents enable fluid, low‑latency speech‑to‑speech interactions that feel more like real conversations than traditional scripted IVRs. Context seamlessly carries over when humans take over, reducing customer repetition. At launch, voice agents support common workflows like billing, payments, and account management, and extend beyond deterministic templates to dynamic, adaptive conversations.

Key Points:

  • Real‑time voice agents are generally available in North America.

  • Speech‑to‑speech agents support interruptions and adapt mid‑conversation.

  • Context carries over smoothly when escalating to human agents.

  • Over 80% of Fortune 500 firms already use Copilot Studio.

Takeaway: With real‑time voice agents, Copilot Studio bridges structured IVR and flexible conversational AI, enabling seamless, context-rich voice support that scales enterprise customer service.

Async’s open benchmark reveals widespread mispronunciation of non‑standard text like dates, numbers, currencies in streaming TTS.

Async—formerly known as Podcastle—has published an open benchmark examining how well commercial streaming TTS systems handle non‑standard text such as dates, phone numbers, and currencies under real production settings. It tests over a thousand sentences and more than 2,200 non‑standard tokens across 31 categories, using providers' streaming APIs without preprocessing. The benchmark uses a scoring model validated by human agreement and exposes surprisingly high failure rates, particularly in number normalization. Async’s own model, Async Flash v1.0, leads in both unit‑ and sentence‑level accuracy. The full dataset, methodology, and audio samples are openly available for the community to explore and expand.

Key Points:

  • Tests span 1,000+ sentences and 2,200+ non‑standard tokens across 31 categories

  • Evaluates via real streaming APIs with zero text preprocessing

  • Scoring uses Gemini 2.5 Pro with >90% human agreement

  • Async Flash v1.0 ranks best in unit‑level and sentence‑level accuracy

Takeaway: Even top streaming TTS engines struggle with everyday non‑standard text—numbers, dates, currencies—which can harm user trust in voice interfaces; explicit, transparent benchmarks help developers address these hidden weaknesses.

This tutorial shows how Deepgram’s Python SDK supports transcription, TTS, async audio workflows, and text analysis in one integrated example.

In this hands‑on tutorial, Asif Razzaq walks developers through using Deepgram’s Python SDK to build a complete voice‑AI workflow. Starting with setup and authentication, the article guides you through using both synchronous and asynchronous clients to handle transcription, speech generation, and text intelligence. Along the way, it shows how to work with real audio inputs and integrate features like summarization and tone detection for richer applications.

Key Points:

  • Sets up Deepgram authentication and both sync and async Python clients.

  • Demonstrates transcription of real audio using SDK’s listen capabilities.

  • Shows text‑to‑speech generation from text using Deepgram’s TTS features.

  • Applies text intelligence: summarization, sentiment, topics, intent analysis.

Takeaway: A practical, all‑in‑one example that brings Deepgram’s speech, TTS, async audio handling, and text‑analysis tools together in Python—ideal for rapid prototyping and voice‑AI workflows.

3CLogic Unveils Smarter Voice AI Tools

3CLogic launches proactive outbound agents, multimodal voice inputs, and automated AI evaluations for service ROI.

3CLogic just supercharged its Voice AI Hub by introducing intelligent outbound agents, multimodal interfaces, and automated evaluation tools. These additions mark a shift from passive notifications to proactive, conversational resolution with visual precision. The new outbound agents can initiate and complete tasks like appointment rescheduling or missing-details follow‑up interactively. Multimodal capabilities empower users to mix spoken and typed inputs—typing email addresses, scanning options, or approving workflows on screen for faster, accurate resolutions. To close the feedback loop, 3CLogic’s AI Agent Evaluator automatically scores every interaction using a customizable questionnaire, bringing transparency and governance into AI performance measurement.

Key Points:

  • Outbound Voice AI agents initiate and resolve customer issues proactively.

  • Multimodal AI lets users type or select info during voice calls for accuracy.

  • AI Agent Evaluator auto-scores agent interactions with configurable questionnaires.

  • All tools integrate natively within CRM or service management platforms.

Takeaway: With proactive voice agents, visual‑voice interactions, and built‑in performance scoring, 3CLogic moves enterprise voice AI into measurable, governed reality—delivering real‑world automation that amplifies both customer satisfaction and ROI.
