UTHealth/ Medstar TTNS Study allows research participants to log their TTNS use and voiding diary using verbal commands right from their Alexa-enabled device. Users will be asked questions regarding their TTNS use, including date and TTNS settings. Users will also have the option to tell the Alexa skill their 2-day voiding diary information. Finally, the Alexa skill has a built-in check if the answers to the diary questions just don't make sense.
