Ud., él, ella ha hablado  Uds., ellos, ellas han hablado

4. Repaso: Present Perfect Indicative
The present perfect indicative is used to say what has or hasn′t happened in a period of time up to the present or to talk about something that happened very recently. Use the present perfect indicative in Spanish when you would use the auxiliary verb ″have″ in English.
   No he hablado con tu suegra.       I haven′t spoken with your mother-in-law.
Use the preterite for past actions that are viewed as over and are not being connected to the present.
   Hablé con tu suegra ayer.       I spoke with your mother-in-law yesterday.

When an object pronoun is used with the present perfect indicative, it should always go before the conjugated form of haber. Unlike the present progressive, a pronoun cannot be attached to the participle.
     Florencia nos ha contado las buenas noticias.
     Me han invitado a la boda.
