Speech Training Mode
When the DKT2020-FDSP is used in speakerphone mode, it adjusts to both the
telephone line’s and room’s acoustic properties. At the beginning of each
speakerphone call, the echo canceller must perform Speech Training by evaluating
both the FDSP user and the far-end user’s voice, background noise and line quality.
➤
To train the speakerphone
➤
The parties at both the local telephone and on the far end should take turns
speaking for approximately 10 seconds.
➤
To improve speaker quality
➤
If the conversation becomes unstable during the call, or there is clipped speech,
feedback or short silences, first try adjusting the volume. This forces the FDSP
phone into speech training mode. The LED will go on.
➤
If conversation is still unstable, press button 10 to activate half-duplex mode. You
can turn off button 10 at any time to reactivate full-duplex mode.
