The concept of audio forensic investigation might have become popular in recent years along with the forensic sciences. The work is done in the audio forensic investigation today based on the pioneering work of these scientists.

In modern cases, law enforcement or other legal professionals (eg, lawyers and prosecutors) or some forensic video companies such as Cognitech will turn into a forensic audio examiner to perform one of a number of services where audio is concerned.

While audio enhancement isn't specifically focused on speech, that is usually the intent behind cleaning up or enhancing audio for legal purposes. It's a means of reducing or filtering out unwanted noise from a poor recording in order to clear up the speech that's covered with noise or is a victim of poor recording methods.
