Depending on what type of cochlear implant and individual hearing loss the person may or may not be able to understand the speech through cochlear implant. Depends on how brain interprets sound and if brain can then improve hearing. It is not just about how loud the sounds are but how the different frequencies put together to be able to understand speech. Each person and case could be totally different if cochlear implants helps understanding of speech or sounds.
