As my voice changes or if I grow, how will that affect my ability to use the FCV Sentinel app?

Since we use Forced Cough Vocalization (FCV) sound signatures, if your voice changes for any reason, your ability to complete a FCV Check may be affected. If these changes are permanent (i.e., growth, surgery, etc.), it will be necessary to repeat the Baseline setting process. 

In these isolated cases, please contact customer service to help you address the matter.
