Villa were beaten 2-1 at Blackburn in the Barclays Premier League on Saturday after David Dunn scored an 88th-minute penalty.
"I feel so much pride when I wear the armband," the Bulgarian told AVTV. "When you lead a club and team like Villa, it's just a great honour. It's a big responsibility.
"But I don't run away from that - I relish it and enjoy it. It's a good thing. Sometimes you have to be vocal on the field and in the dressing room - the lads need encouragement from time to time - and that's my responsibility.
"It was frustrating at the weekend but in general what we have at the moment is a desire to win and a desire to put things right again. We'll bounce back."
Villa face a tough visit from Manchester City in their next game on Monday.
