Hello,

Thank you for your feedback and providing a video of the observed behavior.

Kendo UI for jQuery NumericTextBox applies the WAI-ARIA pattern for Spinbutton. When a spinbutton should have min and max values, they are available for screen readers by setting aria attributes as follows:

• The spinbutton element has the aria-valuemin property set to a decimal value representing the minimum allowed value of the spinbutton if it has a known minimum value.
• The spinbutton element has the aria-valuemax property set to a decimal value representing the maximum allowed value of the spinbutton if it has a known maximum value.

When min and max properties for a NumericTextBox are set, then aria-valuemin and aria-value max are applied to the component and they are read by Narrator - Dojo snippet with NumericTextBox without and with min and max. When there is no min and max range for a NumericTextBox, these attributes are not set and they should not be read by Narrator. Reading them as 0 by Narrator, when there are no such attributes is a Narrator issue. This may be verified also by following the Spinbutton pattern example. Click on the Open in CodePen button on the example and then remove the aria-valuemin="1" and aria-valuemax="31" for the Day spinbutton and wait for it to load the updated example. As a result when the Day splitbutton is clicked, Narrator reads "minimum 0 and maximum 0" as on the video.

I hope this is helpful.
