Compute the fft of the record of my voice

This is my starting code:
a=audiorecorder(8000,8,1);
record(a)
% recording for some seconds, don't remember how many...
stop(a)
data=getaudiodata(a);
plot(data)
I obtained this.
How can I know the duration of the recording (because on the x-axis there are not the seconds...)?
Onother question: how can I compute the fft and find the frequency spectrum of this signal?
Thank you!

N = length(data);
Fs = 8000;
dt = 1/Fs;
t = dt*(0:N-1)';
figure;
plot(t,data);
