What factor is NOT associated with spontaneous recovery from stuttering?

The factor that is not associated with spontaneous recovery from stuttering is the intensity of speech practice. Research indicates that spontaneous recovery is often linked to age of onset, length of time the stuttering persists, and gender.

Younger children tend to have a higher rate of spontaneous recovery, particularly if the onset of stuttering is at a very early age. The longer stuttering lasts, the less likely it is that spontaneous recovery will occur; thus, duration is a significant factor in this context.

Gender differences also play a role, as males tend to stutter more frequently and may experience lower rates of spontaneous recovery compared to females. However, the intensity of speech practice has not shown a direct correlation with the likelihood of spontaneous recovery. Intensive speech practice may help individuals improve their fluency over time but is not a determining factor in natural recovery from stuttering.
