Recording audio narratives is necessary when creating Google Slides presentations, if you plan to use it in the Internet and if the user would like to hear your comments on the content. It is also a great option for teachers who want to create visual manuals and presentations for their students. It is easier for students to understand the material with audio commentary. However, Google Slides does not have an inbuilt tool for audio recording, which is why, in this post, I am going to tell you which free online tools can be used to record your voice.
Preparation of audio files for narratives
- Audio files that you can use in Google Slides. Google Slides supports several file formats: MP3, MPEG, WAV, .OGG, and .OPUS. We recommend using voice MP3 for your narratives.
- Saving files on Google Drive. Save all your audio files in one folder with the presentation itself. If you use a large number of audio files, create a folder named “Audio files” or “Narrations” for them.
- Access to audio files. Open the access to audio files in “View” mode. If you don’t do that, your narratives might not be able to be played by users who do not have access to the audio files.
Review of web services for audio recording
Now, let us look into services that you can use to record voice free. You can use online services that work in browsers, browser expansions for Google Chrome, smartphone record voice app like “Voice Recording,” or record audio on computer (Windows or MAC). But the simplest way is via web services since they do not require software installation, can be used on different devices (personal computers, tablets, smartphones), and often do not require signing up.
