Community testers poring over recent Copilot preview builds have noticed a visual overhaul for Erin, the [assistant’s third avatar](https://www.testingcatalog.com/microsoft-working-on-adding-animated-avatars-to-copilot-voice-mode/). The lava-like blob introduced earlier this year now appears as a stylized red-capped mushroom that fits the softer palette already used for Mika and Aqua.

Strings referencing a fourth avatar, Ellie, have appeared as well. At present, only Ellie’s background loads; the animated figure is absent, hinting that asset work is unfinished and that a release window remains undefined. The slow pace seen with prior avatars suggests deployment could still be months away.

The same builds reveal two additional voices in Copilot’s voice mode: Alder and Elm. A small group of users already see these options, and broader availability is expected once server-side flags roll out more widely. These voices sit alongside the existing set and can be toggled in the assistant’s voice settings panel.

For Microsoft, incremental avatar and voice additions reinforce a strategy of giving [Copilot](https://www.testingcatalog.com/tag/microsoft-copilot/) clearer personality across Windows, web, and mobile clients without altering its underlying language model every cycle. The discoveries stem from standard APK and package teardown methods widely used by the reverse-engineering community, an approach that has become a regular early-warning system for forthcoming Copilot capabilities.
