This project aims to develop an objective diagnostic instrument for ADHD through an automatic voice-analysis system, which uses as input the natural speech of the participants. The underlying voice-analysis procedure was developed by J. Langner at Humboldt University of Berlin (Langner 2003). It ignores the semantic content of spoken words and extracts prosodic and sound features from the speech.
Aims of the study:
- deliver optimized multivariate logistic regression models of prosodic and sound properties of speech for ADHD.
- observe sensitivity and specificity of the voice-analysis procedure.

A behavior disorder originating in childhood in which the essential features are signs of developmentally inappropriate inattention, impulsivity, and hyperactivity. Although most individuals have symptoms of both inattention and hyperactivity-impulsivity, one or the other pattern may be predominant. The disorder is more frequent in males than females. Onset is in childhood. Symptoms often attenuate during late adolescence although a minority experience the full complement of symptoms into mid-adulthood. (From DSM-IV)
A propylamine derivative and selective ADRENERGIC UPTAKE INHIBITOR that is used in the treatment of ATTENTION DEFICIT HYPERACTIVITY DISORDER.
A methylphenidate derivative, DOPAMINE UPTAKE INHIBITOR and CENTRAL NERVOUS SYSTEM STIMULANT that is used in the treatment of ATTENTION DEFICIT HYPERACTIVITY DISORDER.
A dextroamphetamine drug precursor that also functions as a CENTRAL NERVOUS SYSTEM STIMULANT and DOPAMINE UPTAKE INHIBITOR and is used in the treatment of ATTENTION DEFICIT HYPERACTIVITY DISORDER.
The d-form of AMPHETAMINE. It is a central nervous system stimulant and a sympathomimetic. It has also been used in the treatment of narcolepsy and of attention deficit disorders and hyperactivity in children. Dextroamphetamine has multiple mechanisms of action including blocking uptake of adrenergics and dopamine, stimulating release of monamines, and inhibiting monoamine oxidase. It is also a drug of abuse and a psychotomimetic.
