Hmm…try taking out the alias and also mine have the entity_id inside data_templates. Not sure if it makes a difference.

whoishome:
  sequence:
    - service: tts.google_say
      data_template:
        entity_id: media_player.living_room_speaker
        message: >
           Martin is at {{ states.device_tracker.hass_martin_android.state}}. Anke is at {{states.device_tracker.hass_anke_android.state}}
