(Preferably a Bostonian accent, else a New England, or then "Neutral")

A normally reclusive settler has trained her dog to bark and howl the tunes of some popular songs.

Nadia: Is somewhat disheveled and not used to dealing with people, due to her normally reclusive habits. She has been living far off the beaten track with only dogs for company.

Nadia has found that she can train at least one of her dogs (Muttmutt) to "sing" along with the songs on the radio.
She also found out that people will pay to see things like that, so she has forced herself to come to the "big city" to show off her dog's talent and make some money.

When addressing the audience from the stage she comes across as uncomfortable but deals with it by saying what she wants in a loud, authoritative and clipped tone.
