A typical speech enhancement system is similar to a traditional amplification system, consisting of a microphone, digital signal processor, amplifier, and speaker.
The significant difference is that it divides the room into different areas, and the microphones in one area are only connected to the speakers in other areas.
Although standard desktop microphones with voice enhancement systems can be used, ceiling microphones are a better solution.
Firstly, the microphone must have a very compact polarity mode to avoid receiving sound from the speaker, otherwise feedback will be generated and the speech enhancement system will fail.
Secondly, the pickup area of each microphone must be accurately oriented to pick up the desired human voice.
Common hanging omnidirectional or cardioid microphones cannot provide enough Speech enhancement without feedback, and even most array microphones are insufficient in this regard.
