Why a Voice Activated Recorder is a Great Bargain

Jan 18, 2017 | Voice Recorders | 2 comments

A voice activated recorder is a neat device that starts and stops recording automatically depending on whether there is audible sound around it.

How is that useful? In several ways:

Better memory management

Let's say you are in the middle of a classroom lecture and the professor stops to write something or maybe you're interviewing an important contact, and they step out of the room to take a call.

A normal voice recorder will continue recording while you wait but a voice activated recorder will go on standby and resume recording only when the lecture/interview resumes .

This means the voice recorder's memory is better utilized by eliminating silent gaps on the recording.

No manual switching on/off

The situations described in the examples above are not uncommon. You often have to pause or stop recording during a session for a number of reasons.

In a normal voice recorder, you would have to do this manually, but in a voice activated there is no need to press buttons after you have switched it on, leaving you free to focus on the speaker.

This also eliminates the distracting 'beep' that accompanies start/stop/pause functions in most recorders.

No long silences on the recording

Because a voice activated recorder pauses automatically when the speaker is quiet, you end up with a cleaner recording without those annoyingly long periods of silence that you have to skip during playback later.

Better battery life

The auto-pause functionality of voice activated recorders improves battery life because the voice recorder switches to standby-mode when it's not recording.

When you combine these benefits with excellent audio quality, you get a voice recorder that is perfect for lectures, interviews, meetings, and dictations too!
