Alternatively, in the languages I speak:

Welche Sprachen sprechen Sie? (Deutsch/German)

¿Qué idiomas habla usted? (Español/Spanish)

Quelle langue parlez-vous? (Français/French)

EDIT: These sentences are now up to date.

      /\ that’s the more formal way of addressing either a single person or multiple (yeah, this formal pronoun is a bit weird and can be read multiple ways). If you wanna address a group of people more informally: “Welche Sprachen sprecht ihr?”.
