"...speech intelligibility is not always compensated by just amplifying it." In fact, depending on the acoustics of the room, it may just amplify the problem. I had a client with a small multi-purpose space who tried to use it for presentations. He couldn't be understood due to the long reverb time, so he tried using a portable system. It only made the problem worse. After we installed wall and ceiling acoustic panels, he could do presentations unamplified with better speech intelligibility than he had ever experienced in the room. He was delighted with the outcome.
