Geschweifte Klammer neben Baumgraph
Hallo,
Ich möchte 2 senkrechte, beschriftete, geschweifte Klammern neben den Baumgraph setzen. Die erste soll den Bereich 1 bis 2 abdecken. Die zweite den Bereich 2 bis 3.

{\begin{tikzpicture}[->,>=stealth',shorten >=0.5pt,auto,node distance=3cm,
thick,cloud node/.style={cloud,draw,cloud puffs=10,cloud puff arc=120, aspect=2, inner ysep=1em}, circle node/.style={circle,draw}, square node/.style={rectangle,draw}]
\node[cloud node] (ExCloud) {Exemplar cloud};
(1) {1};
\node[below of=ExCloud,yshift=+1.5cm] (average) {Average of the 50 recent exemplars};

\node[circle node] (Ex) [below of=average] {Exemplar};
(2) [below of=a] {2};
\node[square node] (T1) (b) [below left of=Ex] {More talented speaker};

\node[square node] (T0) (b) [below right of=Ex] {Less talented speaker};
