完美的语音清晰度

The basic audio bandwidth is 3.5 kHz. This is what we are all familiar with on the telephone. Overall, 80 percent of the sound frequencies involved in speech transmission are beyond the capabilities of the public telephone standard.

7 kHz quality means a clear improvement in clarity and intelligibility. However, this still covers less than 50% of the audible frequency range. Critical frequencies that are needed for consonant differentiation are still missing.

Enhanced HD Voice by Commend transfers the audio signal at a bandwidth of 16,000 Hz, thus capturing the entire frequency spectrum of the human voice. As a result, voice communication and emergency calls are transmitted at a level of clarity literally unheard-of so far.
