PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic apparatus, an information processing apparatus and an ultrasonic diagnostic program capable of non-invasively performing voice analysis even by a doctor other than an otolaryngologist specializing in acoustic analysis. According to the present invention, a generator, a receiver, and a velocity calculator are provided, the generator is configured to generate ultrasonic waves, and the receiver is the larynx/tracheal wall of a subject. Is configured to be capable of receiving the ultrasonic waves reflected by the, and the velocity calculation unit is configured to analyze the received ultrasonic waves based on Doppler mode, and to calculate the velocity at which the larynx/tracheal wall vibrates. The larynx/tracheal wall has a value of (area S1 in plan view of the larynx/tracheal wall of the subject)/(area S2 in plan view of the larynx of the subject) of 1 to 50. There is provided an ultrasonic diagnostic apparatus, which is an area just below the skin defined to be.
