Hidden Preview Voice tab and voice data training option spotted in Claude apps

Anthropic's Claude apps contain a hidden Voice tab labeled "Preview" and a new option to share voice data for training, according to a post by Testing Catalog (@testingcatalog) on X. The tab suggests Claude may offer an upgraded voice experience.

The report says it is still unclear whether Anthropic is developing its own voice models. The source reports the sharing option and the hidden tab only; it does not describe how the voice data would be used or whether Anthropic has confirmed either feature.
