Conversion of m4a files to txt file format

The only way to achieve audio to text conversion  would be to use some voice transcription software or service, which are designed exactly for this purpose. MPEG-4 format is nowadays very common, so it is likely that it is supported in any such solution. The end result of such m4a to txt conversion would unfortunately not always be perfect and will quiet often require manual post-editing done by human.
