# SpeechToTextButton Appearance

The [SpeechToTextButton](https://www.telerik.com/kendo-angular-ui-develop/components/buttons/speechtotextbutton) provides predefined appearance options such as different sizes, border radii, fill modes, and theme colors. If you omit an appearance property, the active Kendo theme supplies its default value.

Apart from the default vision of the SpeechToTextButton, these alternative styling options enable you to configure each individual aspect of the appearance of a SpeechToTextButton.

* [Size](https://www.telerik.com/kendo-angular-ui-develop/components/buttons/speechtotextbutton/appearance#size)
* [Roundness](https://www.telerik.com/kendo-angular-ui-develop/components/buttons/speechtotextbutton/appearance#roundness)
* [Fill Mode](https://www.telerik.com/kendo-angular-ui-develop/components/buttons/speechtotextbutton/appearance#fill-mode)
* [Theme Color](https://www.telerik.com/kendo-angular-ui-develop/components/buttons/speechtotextbutton/appearance#theme-color)
* [Custom Styling](https://www.telerik.com/kendo-angular-ui-develop/components/buttons/speechtotextbutton/appearance#custom-styling)
* [Active State Styling](https://www.telerik.com/kendo-angular-ui-develop/components/buttons/speechtotextbutton/appearance#active-state-styling)

The following example demonstrates all the available appearance options of the SpeechToTextButton in a single, configurable demo.
