    Speech Material

    Clinical CCi-MOBILE

    Percentage correct mean speech recognitions scores with clinical processor and CCi-

    MOBILE research platform. Error bars represent SEM. N = 8.

    On all measures of test material, the CCi-MOBILE platform achieves

    equivalent speech recognition performance to the clinical processor

    FDA guidelines

    “…we have determined that your study does not fall within

    the scope of the IDE regulation, and an IDE application is not

    required to be submitted to FDA for your proposed study.”

    FDA – Feb., 2017

    CCi-MOBILE platform is meant for “non-clinical” experimental

    investigation of research ideas

    Platform does not fall under the scope of an FDA IDE

    Your organization must have IRB approval from your respective

    institution to conduct any human testing.

    CRSS-CILab submitted an Overview Summary of CCi-MOBILE

    to FDA to assess FDA-IDE status; their response:
