Brief Summary:
The purpose of this study is to see whether participants with persistent developmental disfluency who report fluctuational disfluency due to vocal cord tension on a day to day basis of can achieve a more normalized fluency by identifying dietary allergen responses and subsequently eliminating these dietary triggers from their daily consumption.

Arm Intervention/treatment
Experimental: Food allergy and vocal cord tension
To determine if dietary allergen responses and frequency and severity of vocal cord tension.
Other: Food Allergy Testing and Elimination Diet
Food allergy testing and elimination diet

Primary Outcome Measures :
  1. Dietary Factors and Disfluency: Variations in Severity of Vocal Cord tension [ Time Frame: 1 Year ]

    Initial fluency samples are taken prior to treatment protocol of study.

    Food sensitivity panel will be assessed for potential allergans. Allergan responses are graded from 0 being no response to food allergen to 3 being the strongest response and subsequent removal of sensitive allergan from diet. Speech sample and disfluency severity will be evaluated qualitatively again via the SSI-3 on repeat office visit at fixed interval scale. Erickson S-24 repeated at end of study and final conclusions made.
