Brief Summary
This study proposes to identify acoustic and perceptual markers related to upper motor neuron (UMN) degeneration and lower motor neuron (LMN) degeneration in the dysarthria of patients with amyotrophic lateral sclerosis (ALS) which involves the degeneration of both systems. ALS patients will be gathered in clinical groups according to electromyogram (EMG) and clinical signs observed in the bulbar site. UMN signs are defined as jaw clonus, gag reflex and pseudobulbar features (lability). LMN signs are defined as lingual atrophy and fasciculations. The dysarthria will be compared to dysarthria of patients involving an exclusive UMN system degeneration (in primitive lateral sclerosis) and an exclusive LMN system degeneration (Kennedy's disease). Patients will be compared to the controls who permitted to establish the standards of the "MonPaGe" tool. MonPaGe is a computerized tool based on a multidimensional and quantified assessment of voice and speech, by a set of targeted acoustic and perceptual criteria.

Outcome Measures
Primary Outcomes (1)
Number of patients in each patterns of dysarthria
Patterns of dysarthria will be determined with post hoc unsupervised machine learning method (cluster analysis) from following measurements: * Intelligibility: number of words recognized (score 0 to 15) * Maximum phonation time (TMP), (milliseconds), * Phonation: mean and standard deviation of fundamental frequency (Hz); jitter (%), shimmer (%);Signal to Noise Ratio (dB) * Intensity modulation capacities (score 0 to 4), * Articulation of consonants and vowels : global error score (score 0 to 53); qualitative profile of error; acoustic range variation (Hz), * Coarticulation (Hz), * Score of prosody, * Verbal Diadococinesis : accuracy (score 0 to 4) ; control (score 0 to 4) and flow rate (syllables/sec), * Speech flow rate (syllables/sec).

Eligibility Criteria
We will recruit 80 patients (40 ALS patients, 20 PLS patients and 20 KD patients). They will be recruited at the "centre de référence pour les maladies du motoneurone (Pitié-Salpêtrière). An initial EMG will be achieved during the usual diagnostic management
You may qualify if:
- Major patients diagnosed at the "centre référent des maladies du motoneurone" with ALS, PLS or KD,
- French motherhood language
- Mild to moderate severity of dysarthria according to the Perceptual Score of the BECD
- Without respiratory troubles according to the neurologist
- Without dementia.
You may not qualify if:
- None
