+#Acted Emotional Speech Dynamic Database v1.0
+
+========================ABOUT========================================================
+AESDD v1.0 was created on October 2017 in the Laboratory of Electronic Media, School of 
+Journalism and Mass Communications, Aristotle University of Thessaloniki, for
+the needs of Speech Emotion Recognition research of the Multidisciplinary Media & 
+Mediated Communication Research Group (M3C, http://m3c.web.auth.gr/).
+It is a collection of utterances of emotional speech acted by professional actors.
+This version is the initial state of AESDD. The purpose of this project the continuous
+growth of the database through the collaborative effort of the M3C research group and
+theatrical teams.
+
+========================CREATION OF THE DATABASE=======================================
+For the creation of v.1 of the database, 5 (3 female and 2 male) professional actors were 
+recorded. 19 utterances of ambiguous out of context emotional content were chosen. The 
+actors acted these 19 utterances in every one of the 5 chosen emotions. One extra improvised 
+utterance was added for every actor and emotion. The guidance of the actors and the choice 
+of the final recordings were supervised by a scientific expert in dramatology.
+For some of the utterances, more that one takes were qualified.
+Consequently, around 500 utterances occured in the final database.
+
+UPDATE: Since the AESDD is dynamic by definition, more actors have been recorded and added, 
+following the same naming scheme as described in the Section "ORGANISING THE DATABASE"
+
+========================CHOSEN EMOTIONS================================================
+Five emotions were chosen:
+a (anger)
+d (disgust)
+f (fear)
+h (happiness)
+s (sadness)
+
+========================ORGANISING THE DATABASE==========================================
+There are five folders, named after the five emotion classes.
+Every file name in the databased is in the following form:
+xAA (B)
+
+where 	x is the first letter of the emotion (a--> anger, h--> happiness etc.)
+		AA is the number of the utterance (01,02...20)
+		B is the number of the speaker (1 --> 1st speaker, 2 --> 2nd speaker etc)
+		
+e.g. 'a03 (4).wav' is the 3rd utterance spoken by the 4th speaker with anger
+
+In the case where two takes were qualified for the same utterance, they are distinguished
+with a lower case letter.
+
+e.g. 'f18 (5).wav' and 'f18 (5)b.wav' are two different versions of the 5th actor saying the
+18th utterance with fear.
