However, you might want to say:
* "Hablo en español cada día en clase" - This is a more natural way to say it in Spanish.
* "Siempre hablo en español en clase" - This emphasizes that you always speak Spanish in class.
* "Uso español en clase todos los días" - This focuses on using Spanish in class.
The best way to phrase it depends on the context and the level of formality you want to use.
