作者：

Highlights：

• Spontaneous speech signals are analyzed for Alzheimer's disease diagnosis.

• Data are collected.

• Estimation of the mean square error surface of speech for Alzheimer's patients.

• Using the contour plots quantification of speech during Alzheimer's disease.

• For the first time this analysis is employed for Alzheimer's disease diagnosis.
