8 of the Best Voice Recorders for Online Lectures and Classroom

With almost all children online at some point in the day, voice recorders allow teachers to post lessons for their students to access at any time. This not only helps slow-learners listen, watch and read at their own pace, but it also allows the quicker students to move ahead. Here are eight of the best voice recorders for classroom Lectures.

This is my top pick because I think it is very suitable for classroom teaching. Even when we get back in the classroom, you can record lessons that your students can listen to again and again if they want. Your computer may record your voice, but this gives very good quality sound and is easy to transfer with the built-in USB connection.

This is another good recorder for classroom lectures and online lessons, especially if you want an abundance of features. I don’t need all the features it provides, but, for the money, this is a good choice. It also has a built-in USB port that eliminates cables and recharges the batteries automatically.

1. Olympus WS-853 →

This is my favorite because it is a handy little machine with a great selection of features. You never have to worry about recharging because it automatically recharges when you are using the built-in USB port. You can adjust the quality of sound, but the auto-adjust feature is excellent as you can see in the video below. If you are recording your students’ presentations, it will automatically adjust for loud and soft voices, so all the presentations are clear.

Olympus WS-853
The stereo mic is unique with two directional microphones that are at 90-degree angles. This allows for true stereo sound, and when the presentation is played back, it sounds like you are in the classroom.

It requires two AAA batteries, and if they are rechargeable, you can do it right inside the machine. The battery life is huge at 110 hours, so you can take it on trips or out for the day without worrying it will crash. Your recordings are saved, so even if the batteries die, it will not affect what you already have.

Olympus WS-853
The size is 4.4 x 0.71 x 1.5 inches and the weight is 2.56 ounces. The screen size is 1.5 inches and the memory is 8GB. It plays back excellent MP3 audio.

2. Sony ICD-UX570 →

This model comes close to being my favorite, and it has many useful features, some of which I don’t need. As with the above device, you can plug it directly into your computer, and it will charge while you work. No more cords and connection plugs.

Sony ICD-UX570 Digital Voice Recorder
At full charge, the battery lasts about 27 hours, which is one of the shorter timeframes on this list. It is is 1.43 x 4.31 x 6.13 inches and weighs 1.76 ounces.

It has a stereo microphone as well as voice operated recording. You can select the amount of sound you want to capture with three settings: normal, narrow focus and wide/stereo. I use narrow focus when I am giving a lesson and wide/stereo when I am recording something outdoors when I want to include the ambient sound or in a group discussion when everyone’s voice needs to be heard.

The US570 has improved sound quality compared to previous Sony models. This means each sound is clear and distinguishable. It has a very slim design, so you can carry it in a pocket or bag. The quick-charge feature is useful if the batteries die when you least expect it. With a three-minute charge, you get one hour of recording time.

How to Choose a Voice Recorder for School: FAQ

Recorders provide high-quality playback audio in a lightweight and compact device. Here are some things to think about before you make a purchase.

What about storage capacity?

8MB is the most common storage capacity, but you can get much more capacity if you need it. For example, if you are teaching a second language, you may need files for each student. In this case, you would look for a larger storage capacity such as 32MB or even 128MB.

What about storage capacity?

Is it essential to have a backlit screen?

It is not essential, but it is desirable especially if you plan to record at night. It’s also useful if you are presenting in a darkened room.

Will you only be recording your own voice or will you be recording student’s and other teacher’s voices?

If you plan to record lectures or concerts in a large room, you may like to select a model that filters out ambient sound. The higher the bits per second (bps), the clearer the sound.

Is it all right to buy the cheapest one?

It is not all right to buy the cheapest one if you have a choice. It may work well for a while, but it will wear out quickly and could cause problems when you least expect it.

Digital voice recorders are one of the best tools a teacher can have. In fact, if you get one, you may wonder how you got along without it. It is especially useful for online teaching but will save you a lot of time even in the classroom if you have to deliver the same lesson to several classes.
