Oz Radio: a live presentation paused for a spoken question Illustrative drawing: a live presentation paused for a question. A panel labelled "AI avatar" and "Slide 1 of 5" shows pause bars; below it is a strip of five slide thumbnails, with progress stopped partway through the first. A raised hand asks, in a speech bubble, "What is the difference between a model and an agent?". Slides 2 and 3 are highlighted and outlined, with an arrow down to the citation "From slides 2 and 3".

One question, three frames

    Voice question, transcribed: ‘What is the difference between a model and an agent?’

  3. AI avatar answering from the deck. Panels show the question and the start of the answer: A model is trained to predict the next likely word based on… The frame's label reads AI avatar, synthetic voice.

    Answers from the deck (From slides 2 and 3). The answer ends: ‘The key difference is that an agent can actually get things done, not just talk.’

Frames from one live demo session, 18 October 2026 (UTC). The question was spoken by a synthetic test voice; the presenter is an AI-generated photo avatar.

Present, narrate, podcast

Oz Radio turns PowerPoint decks into AI-presented training: an AI avatar presents your slides live, renders narrated videos, or hosts a two-avatar podcast.

In the live demo, raising your hand pauses the presentation; you ask by voice, and the answer comes from the deck.

Built on Azure AI Speech (Voice Live and batch avatar), Azure OpenAI and Azure Container Apps.

Where it stops

  • The public demo needs no sign-in, is time-boxed and is capped daily, behind hard server-side cost guardrails; its daily budget fails closed.
  • Voice and typed questions are available when the owner enables them.
  • It takes no uploads: it presents decks published for the demo. To present your own deck, deploy it from the source.
  • The frames show one session and one question, not a measure of answer quality.
  • Personal open-source sample, not a Microsoft product.

Let people interrupt

In this session it stopped for a raised hand, and its answer named the slides it came from: two habits I want from any agent.

Bring a workflow.
Let's examine the boundaries.

For conversations about enterprise agents, caller identity, human oversight, or the architecture behind them.
