A free program for Android, by Submersive Bytes.
This app is an easy-to-use, pocket audio recorder (dictaphone). With this, you can easily record your voice, even if you have no knowledge of speaking or recording. It is a handy tool to have for speech recognition and voice dictation.
The application allows you to choose the recording duration and even the number of words to be recorded per sentence.
If you have no idea how to speak or no voice, then the program will provide a selection of common sentences.
In order to be able to save your voice recordings, you will need to grant the application the necessary permissions.
