Abstract: A digital voice recording device includes a storage unit, a display unit, and a processing unit. The processing unit includes a recording module, a storing module, a marking module, and a playing module. The recording module converts audio into digital signals, and records the digital signals into an audio file. Each audio file is associated with a document including textual content of the audio file. The storing module stores the audio file and the document. The display module displays the document. The marking module creates a plurality of flags for the audio file. Each flag is associated with a time point in the audio file, and is assigned an identifier. The playing module identifies an identifier of a flag to acquire a time point in response to a user input, and begin playing the audio file from the acquired time point.
