In the old days, we had to rely on bulky tape recorders that were intrusive and difficult to operate. The tape was expensive and the microphones were large and not very good. Even when the newer cassette recorders were introduced, you still had to make sure the tape was actually moving and that the small microphones weren’t just picking up noise. Today we have tiny digital voice recorders in our smartphones, or more importantly, standalone recorders with remarkably powerful microphones and in a compact size that can easily fit in a pocket or purse.

A voice recorder is a device that converts sound, such as speech and other sounds, into a digital file that can be moved from one electronic device to another, played back by a computer, tablet, or smartphone, and stored like any other digital file. Just as with any digital file, you can send copies to relatives, burn copies to CDs or DVDs and use the audio files as backgrounds for video or slideshow image presentations

One of the largest markets for digital audio devices is the business world where people use digital audio devices to take notes and dictate letters, memos, and other correspondence to assistants for transcribing. The development of digital voice recorders has been significantly influenced by the previous generations of dictating equipment from IBM, Dictaphone, and other manufacturers. But today’s electronic digital voice recorders have moved far beyond mere dictation into the world of high-quality sound recording.

All of these compact audio recording devices use flash memory. Some of them use various types of removable memory but some are limited to the built-in memory. Generally, the more expensive models have both built-in memory and the ability to store files on flash memory cards. Most of the voice recorders, no matter what the price, will record a whole days’ worth of recording time. One important feature that is absolutely necessary is the ability to connect the device to a computer to transfer audio files. This feature is present in nearly all the current digital voice recorders, but some of the very inexpensive ones may lack this feature.

So whether for meetings, interviews, speech improvement,  lectures, or learning a foreign language,  listed below are some of the best mini and voice-activated voice recorders that you can find currently on Amazon.
