  In this paper, we investigate the scalar-induced gravitational waves in
single-field non-attractor inflation for the Pulsar Timing Arrays data. Our
model comprises three phases of inflation: the first and third phases are
slow-roll inflation, while the second phase is a period of non-attractor
inflation. We analyze the model's predictions for various values of the sound
speed $c_s$ and examine the sharp transitions to the final attractor phase.
Furthermore, we study the model's predictions for NANOGrav observations and
future gravitational wave observations. We also calculate the non-Gaussianity
parameter $f_{NL}$ for the non-attractor setup with a general sound speed and
the sharpness parameter.
